Outcomes and impact

  • Widely recognized as increasing academic achievement, cognitive functioning, and social-emotional skills
  • Effects are strongest immediately following preschool but can persist through K-12 schooling, increasing high school graduation, reducing delinquent behavior, and improving mental health
  • Improvements in academic achievement are largest for students from low-income backgrounds
  • Estimated $2-4 economic return for every $1 invested in preschool

Keys to successful implementation

  • Use a proven curriculum design with developmentally-appropriate lesson plans. Activities should focus on developing skills that children will use in kindergarten, such as reading and math.
  • Design professional development plans that ensure staff meets targeted improvement goals and maintain consistency with the curriculum. Teachers should receive coaching at least twice every month.
  • Maintain consistent interaction with parents, both in terms of student progress reporting and inclusion in preschool activities.
  • Programs with longer durations tend to produce stronger outcomes.
  • Include follow up programs that aid the child’s transition to kindergarten, primary school, and even high school.
