The International Dyslexia Association's (IDA) mission is to create a future for all individuals who struggle with dyslexia and other related reading differences so that they may have richer, more robust lives and access to the tools and resources they need.

The IDA is the oldest organization dedicated to the study and treatment of dyslexia. It is also committed to providing complete information and services to address the full scope of dyslexia and related reading and writing challenges. 
Today IDA membership exceeds 10,000 teachers, other professionals, individuals with dyslexia, and parents. The mission of IDA continues to be the same as the mission embraced by the early Orton Society pioneers – seeking to study and treat dyslexia for the benefit of those with dyslexia and their families. In the words of two Orton Society pioneers, Margaret Byrd Rawson and Roger Saunders:

“Dyslexia: The differences are personal; the diagnosis is clinical; the treatment is educational; the understanding is scientific; and the Orton Dyslexia Society serves the united whole.”
