Developmental language disorder (DLD): what NIDCD says about the SLP’s role
NIDCD says that if a doctor, teacher, or parent suspects a child has developmental language disorder (DLD), a speech-language pathologist can evaluate the child’s language skills, and that treatment services “are typically provided or overseen by a licensed speech-language pathologist.” This page quotes NIDCD only.

What DLD is
NIDCD states: “Developmental language disorder (DLD) is a communication disorder that interferes with learning, understanding, and using language.” And: “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 adds: “Learning more than one language at a time does not cause DLD.”
Evaluation
NIDCD says an evaluation generally includes direct observation of the child, interviews and questionnaires completed by parents or teachers, assessments of learning ability, and standardized language tests. It states: “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.”
On learning disabilities: “DLD is not the same thing as a learning disability.” NIDCD calls DLD a risk factor for learning disabilities.
Treatment and settings
NIDCD states: “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.”
- For young children, NIDCD says early treatment can help them acquire missing elements of grammar, expand their understanding and use of words, and develop social communication skills.
- “For school-age children, treatment may focus on understanding instruction in the classroom”.
- “Adults entering new jobs, vocational programs, or higher education may need help learning technical vocabulary or improving workplace writing skills.”
