The Community Preventive Services Task Force recommends full-day kindergarten programs to improve the health prospects of minority children and children from low-income families, based on strong evidence that, compared with half-day kindergarten or full-day kindergarten on alternating days, full-day programs substantially improve reading and mathematics achievement-determinants of long-term academic and health-related outcomes (e.g., reduced teen pregnancy and risk behaviors). The achievement gains apparent at the beginning of first grade do not, themselves, guarantee academic achievement in later years. Ongoing school environments that support learning and development are essential.
社区预防服务工作组建议提供全日制幼儿园项目，以改善少数民族儿童和来自低收入家庭的儿童的健康前景，这一建议基于强有力的证据：与半日制或隔天分上的全日制幼儿园相比，全日制幼儿园能极大地提高阅读和数学成绩——这些是长期学业和与健康相关结果（如降低青少年怀孕率和风险行为）的决定因素。在一年级开始时明显的成绩提高本身并不能保证以后几年的学业成绩。持续支持学习和发展的学校环境是至关重要的。
