Presenting a 45/15 extended school year plan for one New Jersey elementary school, this study includes plans, strategies, and materials used to provide public information; surveys of community attitudes; and evaluation of a pilot project. The school year calendar, pupil and teacher schedules, teacher inservice, and problem issues are presented with illustrations. The curriculum outlines for kindergarten, language arts, mathematics, social studies, science, and special areas are related to the four quarters of the extended school year plans, and provide organization for accommodating the proposed change. Finally, financial implications are presented with comparative cost figures of operational and capital outlay expenditures that show cost benefits. The advisory committee report recommends not implementing the proposed extended school year plan. (DW)
