This review surveys documents, previously announced in RIE, that are concerned with the year-round school (staggered vacation periods) concept. The literature indicates that the year-round school plan should not be considered a panacea for the economic and learning problems in education. Most of the authors agree that schools should weigh carefully the advantages and the disadvantages of such a plan before extending their schedules into the summer months. The author presents briefly those documents devoted to general surveys of year-round plans and treats separately those documents dealing specifically with the Fulton County Four-Quarter Plan, the Valley View 45-15 Plan, or the Dade County Quinmester Plan.
