The major focus of this document is to report the current status of the Iowa-ASSIST program, a statewide education improvement model aimed at helping students, teachers, administrators, and citizens to improve science teaching and science offerings in their communities and schools. Described are procedures for establishing 15 regional service centers, university coordination efforts, program outcomes between 1972-1976, and current trends in Iowa-ASSIST programs. Tables list data regarding workshop offerings and locations, science curriculum (SCIS, ESS, SAPA, and ES/OBIS) implementation within the years 1972-1976, numbers of schools using those selected programs for the same years, and numbers of in-service teachers affected by the Iowa-ASSIST program.
