Supervising the work performance of support staff is a process that is often misunderstood. Although there are several reasons why confusion exists about how to supervise, there is one very common reason: knowing what makes a good supervisor. This course will focus on defining a supervisor's job, as well as how to assist staff in providing the best supports and services possible for people with disabilities. Interactive exercises, detailed case examples, and instructive information make this course helpful for applying this knowledge whenever you may need it. The main goal of this course is to prepare supervisors with knowledge and skills to improve inadequate staff work performance, to support and maintain good staff performance, and to help staff enjoy their work. The American Association on Intellectual and Developmental Disabilities (AAIDD) first developed this course based on results of over three decades of applied research on staff training and supervision. Drawing upon the information presented by Reid, Parsons, and Green in The Supervisor Training Curriculum by the American Association on Intellectual and Developmental Disabilities, this course is part one of three for this curriculum. It is designed for training supervisors, both current and prospective, to take an evidence-based approach in their training, supervising, and motivating of support staff. This first course begins with an explanation of how to make performance expectations clear for staff by using specific methods and tools. The ideal audience for this course includes supervisors, both current and prospective, working in any setting that provides supports and services for people with intellectual or related disabilities.
