A developmental delay refers to a child who has not gained the developmental skills expected of him or her, compared to others of the same age. Delays may occur in the areas of motor function, speech and language, cognitive, play, and social skills.
Signs and symptoms of delay in children vary depending on the type of area affected. 

Assessments can:

1. Help identify possible developmental problems and the need for further evaluation
2. Recognition of the child's strengths and deficits
3 Identification of the children's eligibility for programs (such as early intervention programs)
4. Help in planning appropriate interventions.
