Company founded
1876
Since 1876, the American Association on Intellectual and Developmental Disabilities (AAIDD) has been providing leadership in the field of mental retardation. AAIDD (formerly AAMR) is the oldest and largest interdisciplinary organization of professionals (and others) concerned about mental retardation and related disabilities. Over 7,000 members in the U.S. and 55 other countries have chosen AAIDD as their association. Over the years, we've developed and refined a mission statement and a sense of purpose, which is summarized in our 13-point Principles. Join the leaders. Join AAIDD today. We need your voice.
