Each state has a state Assistive Technology Act Technical Assistance and Training (AT3) Center. These centers were originally funded by the National Institute on Disability and Rehabilitation Research (NIDRR) as part of the Assistive Technology Act of 1998. To locate an AT Act Center in your state, consult the State Tech ACT Projects.
The Association of Assistive Technology Act Programs (ATAP) includes most of the projects, but membership is voluntary. The mission of ATAP is "to set the national direction and advocate for AT Act programs. ATAP will promote and support quality performance of the State AT programs."
