The purpose of the study is to explore whether certain types of intellectual or cognitive tests are reliable, valid, and sensitive to improvement in evaluating treatment responses among individuals with intellectual disability.

Children with Down syndrome often have delays in expressive communication, but we still don’t know enough about how these skills grow and change over time. Because of this, families and professionals often lack clear answers about whether children are “meeting milestones” or when extra support might be needed.
By learning about your experiences, we hope to create a more accurate and meaningful way of monitoring communication development to help families and providers support each child more effectively.
