This manual contains the most current and authoritative information and knowledge on intellectual disability, including best practice guidelines on diagnosing and classifying intellectual disability and developing a system of supports for people living with an intellectual disability.  Written by a committee of 18 experts, Intellectual Disability: Definition, Classification, and Systems of Supports, 11th Edition is based on seven years of work on: (1) a synthesis of current information and best practices regarding intellectual disability; (2) numerous reviews and critiques of the 10th edition of the AAIDD definition manual; and (3) feedback from the field regarding a series of articles published by the Committee. This is the first official AAIDD definition manual with the terminology “Intellectual Disability.”

User's Guide
This practical User's Guide to the 2010 AAIDD Intellectual Disability: Definition, Classification, and Systems of Supports manual informs clinicians, educators, policy makers, and program managers how to implement the various components of the AAIDD definition system in their specific job settings. The authors discuss the contemporary relevance of the supports-based AAIDD definition in the context of issues ranging from special education practices and IDEA mandates, to diagnosing individuals with higher IQ and conducting retroactive diagnoses. Policy makers and program managers will benefit from discussions on how the supports paradigm can improve quality outcomes, and how the current system incorporates the consensus in the field to utilize a supportsbased approach.

Praise for the 11th Edition

“The 11th edition of the AAIDD Definition Manual continues our progress in both describing a person with an intellectual disability in several dimensions, not solely based on IQ or Adaptive Behavior, and integrating further the concept of supports into the definition and practice.  Refinements based on an extensive feedback system, both in the field and in peer-reviewed literature are incorporated making the 11th edition the most advanced tool of its kind.” 
Steven M. Eidelman, Professor and Co-Director, National Leadership Consortium, University of Delaware
"An excellent, up-to-date reference enthusiastically recommended for college library collections and teh resource shelves of aspiring and practicising psychologists."
