Supervisory training for teachers: multiple, long-term effects in an education program for adults with severe disabilities

We evaluated a means of training special education teachers in supervisory strategies for improving specific teaching-related performances of their paraprofessional, teacher assistants. Using classroom-based instruction and on-the-job monitoring and feedback, seven teachers were trained to systematically observe the data collection and teaching performances of their assistants as well as to provide contingent feedback. The supervisory training for teachers, evaluated using a multiple-probe design across groups of assistants, was accompanied by improvements in data collection performances among seven of eight assistants. Improvement in other teaching skill applications also occurred. The improved performance among the assistants was maintained across a 17-month follow-up period. The supervisory training seemed to have multiple benefits in that the teachers' own teaching-related performances improved once teachers were trained to systematically observe and provide feedback to their assistants. The need for continued research is discussed to evaluate the benefits of supervisory training to improve and maintain other important areas of staff performance.
