The A-B plan enables teachers to decrease student load, provides for more preparatory time, and decreases preparations from four to three. In the schools that have implemented this plan, it is popular among the faculties. The literature does not address the problem of at-risk students. This plan relies very heavily on the skill to study independently. There is no evidence that the year-round schedule has a positive impact on achievement.
Studies are ambivalent and poorly conducted.
On the other hand, there is no evidence that academic achievement in a year-round program suffers. Thus, the building can accommodate more students than it is designed to serve. Most year-round programs are designed to serve this purpose. Using a building year-round costs more in maintenance expenses, insurance, teaching personnel, and administration, especially when the hiatus of 15 days is used for supplementary instructional services. The sell is usually made when the public is told that unless a year-round schedule is introduced, higher taxation for building a new school could follow.
