This report summarizes the responses of principals of elementary schools participating in the I/D/E/A Change Program to a survey questionnaire that focuses on program implementation and selected efforts that may be associated with Individually Guided Education (IGE). Survey data are presented for the school years 1973-74, 1974-75, 1975-76, and 1976-77. The number of respondents for each year varied from a high of 466 in 1973-74 to a low of 294 in 1976-77; the 1976-77 respondents were a selected stratified sample of principals drawn from the 1,700 elementary schools that have been involved with IGE since 1970. The survey questionnaire was the same all four years. The report consists mainly of tables that summarize the respondents' answers to questions about how IGE has affected budgets, student achievement, student discipline, and general school operations.
