Past experiments in lengthening the school year have produced mixed results, with savings being realized only over a long period of time. However, increased tax pressure, school overcrowding, and the need for additional educational programs contribute pressures for change. Extended educational opportunity through better utilization of facilities in a lengthened school year can help relieve the strain on both budgets and overcrowded classrooms. Extended school year plans are grouped into staggered attendance programs, summer programs, and extended year plans. When both factors of quality and quantity are considered, an extended school year of continuous study for all pupils seems to offer the greatest promise. Staff and community involvement, support, and preparation are essential to the success of any change. (Author)
