在OST项目的成本结构中，员工工资和福利是最大的也是最一致的因素。根据Kim, Hayden和Mior的研究，员工的薪酬占项目成本的65%到80%，租金和公用事业占15%到20%。Grossman, Lind和Hayes声称运营成本构成了OST项目支出的很大一部分。因此，OST项目的效率更多地取决于运营成本的有效性，而非薪酬。文献表明，项目中工作人员的劳动生产率应该很高，因为他们是这些项目所提供资金的主要消费者。
The staff salaries and benefits constitute the largest and the most consistent element in the OST programs’ cost structure. According to a research by Kim, Hayden, and Mior, the compensation for the staff accounts for 65% to 80 % of the programs cost with the rent and utilities accounting for 15% to 20% of the costs. Grossman, Lind, and Hayes purport that the operations costs constitute a significant amount of the spending on the OST programs. The efficiency of the OST programs is consequently dependent on the effectiveness of the operating costs more so the salaries . The literature implies that the labor productivity of the staff members in the programs should be high as they are the main consumers of the funding provided for these projects.
In order to study the literature, it was required to conduct the exhaustive literature review so as to identify the most appropriate kind of studies conducted on the research topic. There has been a number of evidence which states the benefits of Out of School Time Programs. There is clear evidence about the relationship between the attendance in OST related activities and the positive outcomes of the same . Researchers had found that the youth who did their participation in the programs changed in a number of ways . These students got more and more accomplishments in their carrier. In addition to this, they were not impacted by the crime. Also, these students had a balanced in their life after the OST Programs.
