With a view to deciding on the general design and subject curricula, the framework assembled personnel from the Ministry, KEDI researchers, a basic research team leader, other curriculum experts, school teachers, and subject specialists. Public conferences, seminars, and hearings to formulate and review the overall design were held during the process. The Seventh Elementary and Secondary School Curricula were announced in December 1997 following several series of reviews and corrections. Basically, the NCC acts as a national framework for compulsory content for the first ten years of education, while the school level curriculum - created or adapted -regulates classroom processes.
