This trainer's guide is designed specifically to provide training to individuals with mental retardation or other cognitive disabilities on their rights under titles II and III of the Americans with Disabilities Act (ADA). Written in simple language and supported by drawings that make the material more accessible, the training is meant to give trainees a basic understanding of certain key ADA concepts. Specifically, information is provided on: (1) rights under ADA; (2) recognizing discrimination; (3) what to do in a situation where discrimination happens; and (4) follow-up activities that can be done with local self-advocacy groups. The guide includes a training narrative, trainer's notes and instructions for all activities, 38 masters for making overhead transparencies and for making copies of the Trainee Handbook, and masters for making copies of an ADA help checklist, resource lists, ADA information coupons, and certificate of completion. Each section outlines learning goals and includes a mini-review of the information provided. Two audiocassettes are included for training individuals who also have visual impairments. (CR)
