What it is
Intellectual disability involves differences in intellectual functioning (learning, reasoning, problem-solving) and adaptive functioning (everyday practical and social skills), beginning in the developmental period. Every child is an individual with strengths, and with the right individualized support, children with intellectual disabilities learn, grow, and participate meaningfully. The goal is independence and inclusion.

Evaluation & testing
Intellectual disability is identified through a comprehensive evaluation combining measures of intellectual functioning (a cognitive test) and adaptive behavior (real-world skills), plus developmental history. It's one of IDEA's categories, so eligible students receive an IEP with individualized goals and services.
