This report describes the Teacher Work Group Project to help teachers of students with severe disabilities learn about new teaching practices and implement them in the classroom. Teacher Work Groups (TWGs) were formed at week-long summer institutes and the groups subsequently met during the school year to apply the strategies and learning in the classroom, with the support of project staff. The TWG Project brought together groups of educators in Oregon, Idaho, Ohio, Washington, and Kentucky. Over 3 years the TWG project supported about 265 teachers in 36 groups. The work groups were found to be an effective strategy for providing local support for continued learning, innovation, and change. This report outlines the project rationale, the project design, results of implementation, and program administration. Materials included in the report include: a list of project objectives and the status of each objective and activity; a list of TWG presentations and workshops; a list of 14 publications related to the TWG project; descriptions of the Elementary/Secondary Systems modules; evaluation summaries from institutes and selected workshops; the Teacher Work Group Questionnaire; and a demographic summary of TWGs.
