Developmental Language Disorder

What is developmental language disorder (DLD)?

Developmental language disorder is a persistent difficulty with language itself: understanding it, using it, or both. It interferes with learning, understanding and using language, and it is not explained by another condition such as hearing loss or autism, or by a lack of exposure to language. It can affect speaking, listening, reading and writing.⁠¹

It is not about intelligence. An international expert panel agreed that a DLD diagnosis does not require a gap between verbal and nonverbal ability.⁠⁵ In a UK population study, children with average and low-average nonverbal scores had language problems of the same severity, and the same effect on school progress.⁠³

On terminology: DLD has also been called specific language impairment (SLI), language delay and developmental dysphasia, and you may still see those terms in older reports.⁠¹ The CATALISE consensus recommended “language disorder” for language problems likely to last into middle childhood and beyond that affect everyday life or learning, and “developmental language disorder” when there is no known biomedical cause.⁠⁵ When language problems come with another condition, such as autism or Down syndrome, clinicians say “language disorder associated with” that condition.⁠⁶

How common is DLD, and why is it so often missed?

DLD is common, and often unrecognized. The National Institute on Deafness and Other Communication Disorders (NIDCD) puts it at about 1 in 14 children in kindergarten.⁠¹ A UK population study screened 7,267 children in their first year of school and estimated language disorder of unknown origin, which is DLD, at 7.58 percent: roughly two children in a class of 30.⁠³ A US study of 7,218 kindergartners in the upper Midwest found 7.4 percent, 8 percent of boys and 6 percent of girls.⁠²

For comparison, CDC’s current estimate for autism is about 1 in 31 (3.2 percent) of 8-year-olds.⁠⁷ Yet in the US kindergarten study, the parents of only 29 percent of the children identified had ever been told that their child had a speech or language problem.⁠²

What are the signs of DLD at different ages?

Signs vary with a child’s age and with which parts of language are affected, and some children are first noticed when reading, writing or the vocabulary of school subjects begins.⁠⁶ A child with DLD often has a history of being a late talker.⁠¹

Signs of DLD in toddlers and preschoolers

• Late to put words together into sentences.⁠^1,6
• Slow to learn new words, and difficulty making conversation.⁠¹
• Difficulty following directions, not from stubbornness but because the words are not fully understood.⁠¹
• Frequent grammatical errors, especially on verb endings such as the past tense, and on small words such as articles and pronouns.⁠^1,6

Signs of DLD in school-age children

• Difficulty following classroom instructions and understanding questions.⁠^6,8
• Searching for words, often with filler words such as “um” while they look for the right one.⁠⁶
• Stories told out of order, or without parts a listener needs.⁠⁶
• Trouble with figurative language, jokes and words with more than one meaning.⁠^1,6
• Poor reading or spelling, and disorganized writing with frequent grammatical errors.⁠^1,8
• Math word problems that are hard because of the language in them.⁠¹

Signs of DLD in teenagers

• Limited use of complex sentences, and difficulty finding the right words.⁠¹
• Trouble with hints and things that are not said directly, such as metaphors.⁠⁸
• Difficulty keeping up with fast conversation, slang and acronyms among friends.⁠⁶
• Avoiding conversations with peers.⁠⁶
• Difficulty with the words of particular school subjects, such as science or history.⁠⁶

Some children seem to recover, then struggle again. As schoolwork gets harder, difficulties can resurface: a child who no longer makes verb errors in conversation may still make them in writing. Clinicians call this illusory recovery.⁠⁶

Receptive and expressive language: the two sides of DLD

Language has two sides: receptive language, understanding what is said, and expressive language, putting words together to say something.⁠⁸ An assessment can find a receptive disorder, an expressive disorder, or both, which is called mixed receptive-expressive.⁠⁶

What receptive language difficulty looks like

Receptive difficulty is trouble understanding what is said. It can look like:

• Difficulty following directions and answering questions.⁠^6,8
• Slow to understand new words, especially action words and abstract words.⁠⁶
• Missing the point of a story when it depends on linking sentences and reading between the lines.⁠^5,6
• Missing the meaning of jokes, idioms and words with more than one meaning.⁠⁶
• Missing meaning carried by small grammatical parts, such as word endings.⁠⁶

What expressive language difficulty looks like

Expressive difficulty is trouble putting language together. It can look like:

• Shorter sentences and a slower-growing vocabulary than peers.⁠⁶
• Word-finding difficulty, or leaning on general, all-purpose verbs.⁠^5,6
• Grammatical errors on verb endings, the past tense, small function words and pronouns.⁠⁶
• Stories that are hard to follow because events are out of order or parts are missing.⁠⁶
• Difficulty expressing ideas, feelings and experiences.⁠⁶
• Trouble naming objects, or learning songs and rhymes.⁠⁸

Problems with understanding carry a poorer outlook. In the CATALISE panel’s consensus, prognosis appears particularly poor when receptive language is impaired, and it is also poorer for toddlers with comprehension problems.⁠⁵ They are also easy to misread: a child who does not follow an instruction they did not understand can look as if they are misbehaving.⁠¹

Is it a late talker or DLD?

Many toddlers who are late to talk catch up; some do not. Many late talkers have language skills in the typical range by age 3 to 5, which makes a language disorder hard to diagnose before about age 3.⁠⁶ It is hard to predict which late talkers go on to have lasting problems, partly because some school-age children with language disorder were not late to talk.⁠⁵

Signs that raise the chance of lasting problems, from the research the CATALISE panel summarized:⁠⁵

• Not combining words at 24 months.⁠⁵
• Problems understanding language, not only using it.⁠⁵
• Not communicating with gestures.⁠⁵
• A family history of language or literacy problems.⁠⁵
• At age 4, problems across several areas of language rather than one.⁠⁵
• Language problems still present at age 5 or older, which are likely to persist.⁠⁵

By contrast, preschoolers whose only difficulty is pronouncing sounds generally do well.⁠⁵ CDC’s advice is not to wait: if a child is not meeting one or more milestones, has lost skills they once had, or you have other concerns, talk with the child’s doctor and ask about developmental screening.⁠⁹

How is DLD different from a speech delay?

A speech delay is about producing sounds; DLD is about language. A preschooler whose only difficulty is pronouncing sounds often responds well to therapy and does not meet the criteria for DLD.⁠⁵ DLD is different: it interferes with learning, understanding and using language, and a child with DLD can have difficulty following directions because they do not fully understand the words spoken to them.⁠¹ Sound errors that continue past age 5 usually come with other language problems, so they call for a check of the child’s wider language skills.⁠⁵

Why does DLD get mistaken for something else?

Because the language difficulty is invisible and the behavior it produces is not. A child who struggles with language may avoid interactions and be seen as shy, may not follow directions they did not understand and be seen as disobedient, or may become frustrated and act out.⁠¹ The same child can also be labeled differently depending on who they see: DLD by a speech-language pathologist, dyslexia by a teacher, auditory processing disorder by an audiologist, or ADHD by a pediatrician.⁠⁵

Is it DLD or ADHD?

It can be both. DLD can occur alongside ADHD, and one diagnosis does not rule out the other.⁠⁵ In US children, the co-occurrence of ADHD and DLD is estimated at about 22 percent.⁠⁶ ADHD is diagnosed by a doctor or psychologist who asks about the child’s behavior at home, at school and with peers, while a speech-language pathologist’s assessment looks at language itself.⁠^1,10

Is it DLD or a behavior problem?

A child who cannot explain themselves has fewer ways out of a hard moment. Children with language disorders are at higher risk of emotional and behavioral difficulties, and their behavior is easily misread.⁠⁶ Among children aged 5 to 13 formally identified with emotional and behavioral disorders, one study found 81 percent had a language disorder.⁠⁶ When a child is struggling at home or at school, NIDCD advises finding out whether language is part of the problem.⁠¹

Is it DLD or dyslexia?

They overlap and often occur together. Dyslexia is a difficulty with reading and spelling; DLD is a difficulty with spoken language. One US study found that 54 percent of children with DLD also had dyslexia, and 71 percent of children with dyslexia had DLD.⁠⁶ Children with dyslexia often have language weaknesses beyond sounds, and a tutorial on the overlap advises targeting a child’s own strengths and weaknesses rather than the label.⁠¹²

Is it DLD or autism?

Autism is a separate diagnosis, and many autistic children also have a language disorder. When language problems occur with autism, they are called language disorder associated with autism rather than DLD.⁠^5,6 In US samples of 8-year-old autistic children, between 23.6 and 63.4 percent had a language disorder.⁠⁶ Difficulty with the social use of language is a hallmark of autism, but it also occurs in children who are not autistic.⁠⁵

Is it DLD or a language processing disorder?

The name can depend on who describes the problem. ASHA notes that the terms for a disorder in processing auditory information, which include auditory processing disorder and language processing disorder, vary with the professional describing it, and that central auditory processing disorder may co-occur with a language disorder and has to be told apart from it.⁠¹¹ Children given an auditory processing diagnosis often have language problems that need expert evaluation.⁠⁵

What causes developmental language disorder?

No single cause is known. DLD is a neurodevelopmental disorder that comes from complex interactions between genes and the environment that change brain development, and the exact causes are unknown.⁠¹ It runs in families: 50 to 70 percent of children with DLD have at least one family member with the disorder.⁠¹

Risk factors found more often in children with language disorders include a family history of language disorders or dyslexia, being a boy, being a younger sibling in a large family, and fewer years of parental education. They do not predict the outcome for an individual child, and having them does not rule out a DLD diagnosis.⁠⁵

Can bilingual children have DLD?

Yes, but learning two or more languages does not cause DLD, and it does not harm a child who has it. DLD affects all the languages a child speaks, and a multilingual child with DLD does not struggle more than a child with DLD who speaks one language.⁠¹ Using more than one language at home does not confuse or delay a child, and parents can speak the languages they are most comfortable using.⁠⁸

A child who scores low on an English test because they have not yet had enough English does not have a language disorder; DLD is considered only when the child does not have age-appropriate skills in any language.⁠⁵ So an assessment looks at every language the child uses, with an interpreter where needed, and few standardized tests exist in the US for children who use languages other than English.⁠⁶

When should you ask for a language evaluation?

Ask if your child is not meeting language milestones, or if you think there could be a problem with the way your child plays, learns, speaks, acts or moves.⁠¹³ Where to start depends on age:

• Lost skills. If your child has lost skills they once had, do not wait: talk with your child’s doctor and ask about developmental screening.⁠⁹
• Under 3. Contact your state’s early intervention program yourself. You do not need a doctor’s referral, and the evaluation is free.⁠^13,14
• Age 3 and older. Call any local public elementary school, even one your child does not attend, and ask for an evaluation through the school system.⁠¹³
• School-age children and teens. A parent can request an initial evaluation from the school, and a written request gives you a dated record. The school must evaluate within 60 days of your consent, or within your state’s timeline.⁠¹⁵
• At any age. A hearing check belongs in the process, to rule out hearing loss as part of the problem.⁠⁶

RelatedSchool evaluation request letterEarly intervention vs private therapy

How is developmental language disorder diagnosed?

A speech-language pathologist (SLP) diagnoses DLD. When a doctor, teacher or parent suspects it, an SLP evaluates the child’s language, compares it with that of same-age peers, identifies the specific difficulties and plans treatment.⁠¹ An evaluation usually includes:

• A case history: birth, medical and developmental history, any family history of speech, language or reading problems, the languages the child uses, and the concerns of parents and teachers.⁠⁶
• A hearing screening, if one was not already done.⁠⁶
• Observation of the child, and questionnaires for parents and teachers.⁠¹
• Standardized tests and informal measures of vocabulary, grammar, understanding, conversation and storytelling.⁠^1,6
• A look at reading and writing, because spoken and written language are closely connected.⁠⁶
• A check of the structure and movement of the mouth for speech.⁠⁶
• Sometimes other professionals, such as a psychologist for thinking skills, to rule out other conditions.⁠⁶

The result can be a language difference rather than a disorder, or a diagnosis of a receptive, expressive or mixed language disorder, with a description of its severity and recommendations.⁠⁶ ASHA advises against requiring a gap between IQ and language scores before a child can receive language services.⁠⁶ The DSM-5 calls the diagnosis language disorder and no longer requires nonverbal IQ in the typical range, and the UK population study concluded that access to services should not depend on it.⁠³

Some children are not diagnosed until middle or high school.⁠⁸

What treatment helps DLD, and how strong is the evidence?

Speech and language therapy, aimed at the areas the assessment identifies. Treatment is provided or overseen by a licensed speech-language pathologist, at home, at school, in clinics or in hospital outpatient settings.⁠¹ Its goal is to build language skills in context, so that everyday communication and access to schoolwork improve.⁠⁶ What it targets changes with age:

• Preschoolers: grammar, vocabulary, conversation and storytelling, and early literacy.⁠^1,6
• School-age children: following directions, understanding the words teachers use, organizing information, and speaking, reading and writing, tied to the curriculum.⁠^1,6
• Teenagers: strategies that work around language difficulties, direct teaching of subject vocabulary, and learning to speak up for themselves in class.⁠⁶
• Adults: technical vocabulary for a new job or course, and workplace writing.⁠¹

How strong is the evidence for DLD therapy?

• Therapy in general. An older meta-analysis of trials in children with speech and language delay or disorder found therapy may be effective for speech sound and expressive vocabulary difficulties, with mixed evidence for expressive grammar and little evidence available for difficulty understanding language. Therapy lasting more than 8 weeks was a possible factor in good outcomes.⁠¹⁶
• Parents as part of therapy. In the same analysis, no significant differences were found between therapy given by trained parents and therapy given by clinicians.⁠¹⁶ A meta-analysis of 18 studies of children aged 18 to 60 months with language impairments found that interventions delivered by trained parents improved both understanding and expressive language.⁠¹⁷
• Who delivers it. A 2019 review found good evidence for direct, individual therapy by an SLP for children with pervasive or complex language disorders, while children with milder difficulties can progress when an SLP plans the work and trained, supported and closely monitored staff deliver it.⁠¹⁸
• Timing. Early treatment can improve the skills of many preschoolers, and children who start school with significant language delays, and even older children, can still benefit.⁠¹

An approach to avoid. Auditory integration training is promoted for auditory processing problems, dyslexia and learning disabilities, and ASHA’s review concluded it has not met scientific standards for efficacy.⁠⁶

Why the name matters. The CATALISE panel agreed on one term because inconsistent labels for children’s language problems were affecting access to services as well as research.⁠⁵

What does speech therapy for DLD look like?

The first visit. Expect a case history, questions for you and often for teachers, observation of your child, a hearing screening if one was not already done, and formal and informal language tasks.⁠^1,6 The results describe which areas of language are affected and how much, with recommendations.⁠⁶

The sessions. Therapy may be one-on-one, in small groups, or in the classroom or community.⁠⁸ Group sessions let children use new skills in natural conversation, and some assessment and therapy can be done by telepractice, under rules that vary by state.⁠⁶ How often and how long depends on the child’s goals, and more sessions do not always mean better results.⁠⁶ Many plans include you: SLPs can train parents and caregivers to carry the work into daily life.⁠⁶

How progress is measured. Clinicians track progress with standardized tests and with informal measures, benchmarks and progress reports, and keep monitoring after therapy ends, because difficulties can resurface as language demands grow.⁠⁶ At school, an IEP has to say how progress toward each annual goal is measured and when you receive progress reports.⁠¹⁵

How can parents help a child with DLD at home?

Parents and caregivers can help a child with a language disorder communicate better. ASHA’s public information site suggests:⁠⁸

• Talk and read together every day.⁠⁸
• Name objects, signs and actions as you go through the day.⁠⁸
• Encourage your child’s questions and conversation, and answer their attempts to communicate.⁠⁸
• Speak in the language or languages you are most comfortable using.⁠⁸
• Choose interactive activities over screen time.⁠⁸

Ask your child’s SLP to show you specific techniques. Clinicians use expansions, repeating what a child said and adding grammar or detail, and recasts, repeating it in a different form, and SLPs can train family members to use techniques like these at home.⁠⁶ For young children with language impairments, interventions delivered by trained parents improved language in a meta-analysis of 18 studies.⁠¹⁷

DLD at school: evaluations, IEPs and classroom support

Almost everything in a classroom runs on language. In the UK population study, 88 percent of children with language disorder at school entry were not making expected academic progress.⁠³ Children who start school with oral language problems are at risk of reading problems, so reading is worth watching closely.⁠⁵

Special education for DLD: IEPs and 504 plans

Under federal special education law, a speech or language impairment, including a language impairment that adversely affects a child’s educational performance, is a disability category.⁠¹⁵ Children with language disorders who qualify receive services through an IEP under that category; younger children may qualify under developmental delay, and older ones often under specific learning disability. Educational performance is not limited to grades.⁠⁶

Either a parent or the school can ask for an initial evaluation, and once you consent it must be completed within 60 days or your state’s timeline. Schools must look for children who may need special education even when they are passing from grade to grade, and services under an IEP are provided without charge.⁠¹⁵ A student with a speech or language impairment who does not qualify under the law may be eligible for a 504 plan.⁠⁶

RelatedSchool evaluation request letterIEPs and 504 plans

Classroom support for DLD: what is recommended and what is tested

Advice for teachers on DLD is widespread online: break down instructions, use short simple sentences and slow down, pair spoken instructions with visuals or written ones, pre-teach key vocabulary, and give extra time to process and respond.⁠¹⁹

A 2026 systematic review found only 11 peer-reviewed studies of whole-class approaches for students with DLD; they showed gains in oral language, vocabulary, grammar and understanding idioms. Many of the commonly recommended strategies have not been tested across a whole class or the school day; the ones that match tested approaches are vocabulary teaching, visuals, changing the language of instructions, and modeling.⁠¹⁹ The reviewers recommended that teachers and SLPs work together and track whether a strategy is helping the student.⁠¹⁹

Does DLD go away?

No. DLD usually continues into adulthood, and its signs change with age. A young child might use ungrammatical sentences, while a young adult might avoid complex sentences and struggle to write clearly.⁠¹ Language problems still present at age 5 or older are likely to persist, with little evidence that the gap closes over time.⁠⁵ Children who improve with therapy typically do not catch up with their peers, and their language growth may level off in early adolescence.⁠⁶

That is not a reason for pessimism. People can benefit from treatment whenever it begins, and many adults develop strategies for managing DLD that improve their social, family and work lives.⁠¹

What happens with DLD in the teenage years and adulthood?

School and work. School demands rise in the teenage years, and therapy for adolescents tends to teach ways around language difficulties and how to speak up for themselves in class.⁠⁶ Fewer students with spoken language disorders finish high school or earn a college degree than their peers.⁠⁶ In a UK study of 84 young adults with a history of DLD and 88 peers, at an average age of 24, those with DLD had lower qualifications and more often worked in nonprofessional jobs, but similar proportions were employed, incomes were broadly comparable within the same types of job, and a smaller but not trivial share had good educational and employment outcomes.⁠²⁰

After high school. College and training programs do not provide support automatically: students have to disclose their disability and provide current documentation, and the supports differ from those in school. SLPs can be part of transition planning in high school.⁠⁶

Mental health. In a meta-analysis of 8 cohorts, children with language impairments were about twice as likely as their peers to show clinical levels of emotional, behavioral and ADHD problems later in childhood and adolescence, though the studies were few and varied.⁠²¹ In a UK follow-up from 16 to 24 years, anxiety stayed higher than in peers, and depression symptoms were higher at 16, fell after compulsory schooling and rose again by 24; the researchers pointed to support during the transitions from adolescence to adulthood.⁠⁴ Children with language disorders are also at higher risk of bullying.⁠⁶

Adults. By adulthood, people with DLD are six times more likely to be diagnosed with reading and spelling disabilities, and four times more likely to be diagnosed with math disabilities, than those without DLD.⁠¹ In a small study of 17 men with severe receptive DLD in childhood, followed into their mid-thirties, the language disorder persisted, with severe literacy problems and more unemployment and fewer close relationships than their siblings.⁠²² Adults starting a new job, training program or college course may need help with technical vocabulary or workplace writing, and treatment can still help.⁠¹

Who pays for DLD evaluation and therapy?

• Under 3: early intervention. Evaluation and assessment, service coordination and the family service plan are provided at public expense with no fees to parents. States may charge sliding-scale fees for some services, and a family the state finds unable to pay receives all services at no cost.⁠¹⁴
• Age 3 and older: public schools. Special education and related services under an IEP are provided without charge.⁠¹⁵
• Medicaid. Children under 21 enrolled in Medicaid are covered through EPSDT for medically necessary services to correct or reduce health conditions, including services outside the state’s plan.⁠²³ Medicaid’s services for speech, hearing and language disorders are provided by or under the direction of a speech pathologist, on referral from a physician or other licensed practitioner.⁠²⁴
• Private insurance. Marketplace plans cover habilitative and pediatric services as essential health benefits, but the specific services vary by state, and large self-insured employer plans do not have to cover them. Check your plan’s speech therapy benefit.⁠²⁵

How do you find a speech-language pathologist for DLD?

Look for a licensed SLP who works with children’s language, not only speech sounds. A full evaluation covers understanding and expression, reading and writing, every language the child uses, and what parents and teachers see, and progress is tracked with tests and reports over time.⁠⁶ Questions worth asking:

• Do you assess understanding as well as speaking, and check reading and writing?
• How do you assess a child who uses more than one language?
• How do you involve parents and teachers?
• How do you measure progress, and how often do you report it?

   The page: “Developmental language disorder (DLD) is a communication disorder that interferes with learning, understanding, and using language. These language difficulties are not explained by other conditions, such as hearing loss or autism, or by extenuating circumstances, such as lack of exposure to language. DLD can affect a child’s speaking, listening, reading, and writing. DLD has also been called specific language impairment, language delay, or developmental dysphasia. It is one of the most common developmental disorders, affecting approximately 1 in 14 children in kindergarten. The impact of DLD persists into adulthood”; “DLD is a neurodevelopmental disorder. Neurodevelopmental disorders are caused by complex interactions between genes and the environment that change brain development. The exact causes of the brain differences that lead to DLD are unknown”; “50 to 70 percent of children with DLD have at least one family member with the disorder”; “Learning more than one language at a time does not cause DLD … For multilingual children, DLD will impact all languages spoken by a child. Importantly, learning multiple languages is not harmful for a child with DLD. A multilingual child with DLD will not struggle more than a child with DLD who speaks only one language”; “A child with DLD often has a history of being a late talker … Although some late talkers eventually catch up with peers, children with DLD have persistent language difficulties”; younger children may “Be late to put words together into sentences. Struggle to learn new words and make conversation. Have difficulty following directions, not because they are stubborn, but because they do not fully understand the words spoken to them. Make frequent grammatical errors when speaking”; older children and adults: “Limited use of complex sentences. Difficulty finding the right words. Difficulty understanding figurative language. Reading problems. Disorganized storytelling and writing. Frequent grammatical and spelling errors”; “Language difficulties may be misinterpreted as a behavioral issue. For example, a child who struggles with language may avoid interactions, leading others to think that the child is shy. A child may not follow directions because they don’t understand the instructions, but others may interpret this as misbehavior. A child who struggles to communicate may become frustrated and act out. When a child is struggling at home or in school, it is important to determine if language difficulties may be part of the problem”; “If a doctor, teacher, or parent suspects that a child has DLD, a speech-language pathologist … can evaluate the child’s language skills … Direct observation of the child. Interviews and questionnaires completed by parents and/or teachers. Assessments of the child’s learning ability. Standardized tests of current language performance. These tools allow the speech-language pathologist to compare the child’s language skills to those of same-age peers, identify specific difficulties, and plan for potential treatment targets”; “DLD is not the same thing as a learning disability. Instead, DLD is a risk factor for learning disabilities since problems with basic language skills affect classroom performance … Difficulties with language comprehension can make mathematical word problems challenging. Some children with DLD may show signs of dyslexia. By the time they reach adulthood, people with DLD are six times more likely to be diagnosed with reading and spelling disabilities and four times more likely to be diagnosed with math disabilities than those who do not have DLD”; “This does not mean that, as children develop, they grow out of the problem. Instead, the condition is apparent in early childhood and will likely continue, but change, as they get older. For instance, a young child with DLD might use ungrammatical sentences in conversation, while a young adult with DLD might avoid complex sentences in conversations and struggle to produce clear, concise, well-organized, and grammatically accurate writing”; “Early treatment during the preschool years can improve the skills of many children with language delays, including those with DLD. Children who enter kindergarten with significant language delays are likely to continue having problems, but they and even older children can still benefit from treatment. Many adults develop strategies for managing DLD symptoms. This can improve their daily social, family, and work lives”; “Treatment services for DLD are typically provided or overseen by a licensed speech-language pathologist. Treatment may be provided in homes, schools, university programs for speech-language pathology, private clinics, or outpatient hospital settings”; “people can benefit from treatment regardless of when it begins”; early treatment can help young children “Acquire missing elements of grammar. Expand their understanding and use of words. Develop social communication skills”; school-age treatment “Following directions. Understanding the meaning of the words that teachers use. Organizing information. Improving speaking, reading, and writing skills”; “Adults entering new jobs, vocational programs, or higher education may need help learning technical vocabulary or improving workplace writing skills”.

Statement 2: “The term ‘language disorder’ is proposed for children who are likely to have language problems enduring into middle childhood and beyond, with a significant impact on everyday social interactions or educational progress”. Statement 3: “Many toddlers who have limited vocabulary at 18–24 months catch up”; “Children who fail to combine words at 24 months appear to have worse outcomes”; “Prognosis is also poorer for children with comprehension problems, those who do not communicate via gesture”; “A positive family history of language or literacy problems is an additional risk factor”; “the prediction from late language emergence to subsequent language disorder at school age is surprisingly weak: in part because many late talkers catch up but also because some school-aged children with language disorder were not late to talk”; “in 4-year olds, the greater the number of areas of language functioning that is impaired, the higher the likelihood that the problems will persist into school age”; “there is generally a good prognosis for preschoolers whose problems are restricted to expressive phonology”; “Language problems that are still evident at 5 years and over are likely to persist”; “Children who start school with oral language problems are at risk of reading problems and poor academic attainment … with little evidence that the language gap closes over time”; “Prognosis appears particularly poor when receptive language is impaired”. Statement 4: language needs from limited exposure to the school language “should not be regarded as language disorder, unless there is evidence that the child does not have age-appropriate skills in any language”; “multilingualism does not lead to language problems”. Statement 6: differentiating conditions include brain injury, cerebral palsy, sensorineural hearing loss, Down syndrome, “autism spectrum disorder (ASD) and/or intellectual disability”, referred to as “‘Language disorder associated with X’”. Statement 8: “a large discrepancy between nonverbal and verbal ability is not required for a diagnosis of DLD”. Statement 9: co-occurring conditions “include attentional problems (ADHD), motor problems (developmental coordination disorder or DCD), reading and spelling problems (developmental dyslexia)”; “the same child may be regarded as having DLD by a SLT/P, dyslexia by a teacher, auditory processing disorder by an audiologist, or ADHD by a paediatrician”; children given an auditory processing diagnosis “often have co-occurring language problems which require expert evaluation”. Statement 10: risk factors “include a family history of language disorders or dyslexia, being male, being a younger sibling in a large family and fewer years of parental education”, which “are not robust predictors of individual children’s language status or outcome”. Statement 11: “general all-purpose verbs”; children who “interpret one sentence at a time, without drawing the necessary inferences”; “Phonological errors of this kind are common in early development, but can persist and, when numerous, impair intelligibility of speech”; “Phonological problems in preschoolers that are not accompanied by other language problems … often respond well to specialist intervention … they would not meet our criteria for DLD”; “Where phonological problems continue beyond 5 years of age it is important to assess the child’s broader language skills, as persisting phonological difficulties are usually accompanied by other language problems”; pragmatic difficulties “are hallmarks of the communicative problems seen in ASD, but are also found in children who do not meet criteria for autism”.
