They may recommend a formal assessment and evaluation.It may be difficult to assess very young children for intellectual disability.If it appears your child might have an intellectual disability, the school will have your child tested by the school's psychologist (without charge).
However, simply having some developmental delays does not meet the full criteria for intellectual disability.
A common example would be a child with Down syndrome.
If you have any concerns about your child's social, emotional, physical, or intellectual development, talk to your child's doctor.
Sometimes a child is too young to be properly assessed.
Other times, the child may not be able to complete tests.
