The rising costs of education could be reduced by substituting a four-quarter rotational school calendar for the traditional school calendar. Under this system, each student would attend three continuous quarters and have the fourth quarter off. One fourth of the students would thus be on vacation each quarter, and one-fourth less teachers would be required. However, teacher salaries would rise to compensate for the 12-month contracts. The need for physical facilities would fall proportionately, providing an additional source of savings which would counteract the taxpayer rebellion that has manifested itself in reduced school revenues. These savings could be applied toward acquiring instructional materials for individualized instruction. Some social problems caused by inactive youth would be reduced since fewer would be on vacation at one time. Economic efficiency would be enhanced if employers could depend on student labor year around. (LN)
