FTCE Exceptional Student Education (ESE) K-12 Practice Test 2026 - Free ESE Practice Questions and Study Guide

The correct answer is the American Association on Intellectual and Developmental Disabilities (AAIDD). This organization is well-known for its extensive work in the field of intellectual and developmental disabilities, specifically in establishing standards for definitions and classifications. They publish comprehensive manuals that outline the criteria for diagnosing and understanding various intellectual disabilities, which are crucial for professionals working in special education and related fields.

The other organizations mentioned play important roles in the broader realm of special education and advocacy but do not specialize in defining and classifying intellectual disabilities in the same way that AAIDD does. For instance, the National Association of Special Education Teachers focuses more on the professional development and support of educators in special education. The Council for Exceptional Children is dedicated to improving educational outcomes for individuals with exceptionalities but does not publish specific definitions and classifications for intellectual disabilities. The American Psychological Association contributes to the field of psychology and publishes resources related to psychological assessments and practices, but it does not specifically focus on the classification of intellectual disabilities like AAIDD does.
