When working to identify significant delays or disorders that may qualify a child for special education services, you combine your data with observations.

Explanation:

The team that is put together by the school will use assessments and testing for the child in question. Observation of the child is the most important because the team can visibly see what is going on with the child during class, playtime, and the child alone. Seeing the child's performance themselves help them to understand more about the delay or disorder the child may have.
