The purpose of this study was to examine the feasibility of a continuous school year plan -- the 45-15 plan -- for the Boise Public Schools. Under this plan, students would attend school for 45 days and be absent from school for 15 days in rotating shifts throughout the year. Eleven subcommittees researched various aspects of a continuous school year, such as calendars, staff relations, census and attendance, pupil personnel services, maintenance, climate control, public relations, data processing, government and institutional relations, and curriculum planning. The reports of these subcommittees make up the bulk of this presentation. As a result of study findings, it was established that year-round schooling is a viable educational program for the Boise schools. In addition, a simulation program evidenced that the school staff had the capability of developing the necessary calendar, that the existing facilities could accommodate 25 percent more pupils under an extended year calendar, and that the amount of education for the dollar over the long term would be greater than under the present 9-month system. However, three objections to the program were voiced by the school authorities: (1) primary grade children should not be required to change teachers every 45 days, (2) well-established extracurricular and enrichment programs would have greater difficulty in maintaining their high standards, and (3) the question of summer employment for youth would still remain unsolved.
