This manual describes a program for training direct service staff to teach adaptive skills to people who have severe disabilities. Research has demonstrated that the Teaching-Skills Training Program improves on-the-job work performance of staff while teaching clients, requires a small amount of trainer and trainee time (typically less than one work day), is well accepted by direct service staff, and results in significant gains in adaptive skill development for clients. Following the introductory chapter 1, which defines the purpose of the manual, chapter 2 discusses the program's four sets of teaching skills: (1) teaching program steps in the appropriate order; (2) using a least-to-most assistive prompt strategy; (3) reinforcing client behavior, and (4) error correction. Chapter 3 introduces the program's three main components: classroom-based training, on-the-job monitoring and feedback, and supervision and maintenance. Chapters 4 through 6 provide detailed guidelines for staff development in each of these three components. Among eight appendices are information on a related videotape, sample client teaching programs with task analyses, a behavioral teaching terminology quiz, a teaching skills observation form, and a teaching skills supervisor feedback checklist.
