A ten-member committee was established to identify and illustrate the factors that significantly affect the articulation and compatibility of elementary and secondary school programs resulting from year-round school operation. The committee authorized six projects to implement its purposes. These projects were to create a library of year-round school materials, to survey local year-round schools, and to study vocational education, air conditioning, summer school articulation, and high school patterns as they relate to year-round schedules. Reports of these projects are in another volume. This report is presented in a format that reflects the three basic areas identified for study: community scheduling (planning time, real and imagined difficulties of the extended calender, compatibility of adult work schedules in the extended calendar, youth job opportunities with the extended calendar), curriculum and instruction (desirability of pilot programs versus total district involvement, scheduling flexibilities, advantages of intersessions, financing curricular changes), and legal and personnel (legal factors, personnel factors, program planning factors).
