This third report of the Commission on Public School Personnel Policies in Ohio follows up on its first report (SP 006 262) which recommended that school districts build flexible staffing arrangements into their own school organizations. This report centers on descriptions of flexible staffing arrangements made in the Ohio schools. Flexible staffing is defined as a group of teachers working cooperatively to determine the learning needs of a group of students and to determine plans to help those needs. The two common patterns of flexible staffing are described as team teaching and differentiated staffing (in which there is a variety of roles on each instruction team). The report reviews problems of cost, physical facilities, in-service training, and implementation strategies. Appendixes include information sources, project summaries, and a superintendents' survey.
