This is a report on Phase I of a two-phase project identifying the requirements of administrators, teachers, and school board members for implementing an individualized instruction program, identifying such programs in the United States, and selecting 48 for site visits. A preliminary questionnaire was administered to 21 Oregon public school superintendents and the data, with data from interviews with 38 members of the target audience, were used to construct a second questionnaire covering seven major areas--effects on students, operation of individualized programs, teachers, costs, facilities and equipment, materials, and implementation. This questionnaire was administered to all segments of the target audience in upper New York State, Maryland, mid-Texas, southern California, and the Northwest, with a further classification of school districts as small rural, large consolidated rural, suburban, and central city. On-going programs were identified through chief state school officers, directors of regional educational laboratories, colleges and universities, the U.S. Office of Education, and the National Education Association, to obtain a comprehensive view, compile a selected list of programs in each state, and select the most diversified for site visits. Appendixes provide examples and more detailed information on questionnaires, interviews, programs identified, program identifiers, and site visits. (MBM)
