The described inservice program was designed to bring together teachers to collectively address overall school problems. The project was based upon the belief that school improvements could be best effected by providing teachers the opportunity to actively participate in the design and implementation of changes in school functioning. Emphasis was placed on helping the staff acquire skills in problem solving, goal setting, decision making, planning, information gathering, problem analysis, and resource identification. An example is given of a team of teachers who identified specific problems encountered by regular class teachers in dealing with mainstreamed students. Their recommendations are outlined, and subsequent improvement of the situation is described. (JD)
