In 1975, the Competency Based Curriculum (CBC) was adopted as a vehicle for achieving excellence in the District of Columbia public schools. A total of 213 elementary and secondary school teachers and 16 instructors participated in the inservice course "Foundations of Curriculum Writing for CBC." The participants were divided into six instructional groups by subject area. The main objective of the course was to provide the participants with the skills and competencies to produce CBC curriculum materials in selected subject areas. In their own self-assessment, participants felt they had gained the skills and knowledge to enable them to produce these curriculum materials. Participants registered a number of suggestions for improving the program, but were satisfied with the instructors, the instruction and the facilities. Those who were later chosen to write the CBC curriculum materials felt they had been well prepared for their task. Participants received two inservice credits for satisfactory completion of the course. (Author/GC)
