Health Factors  
Decision Makers

The HighScope Perry Preschool program, conducted from 1962 to 1967 in Ypsilanti, Michigan, was offered to African-American children from neighborhoods with low incomes. Teachers were certified with at least a bachelor’s degree, the average child-teacher ratio was 6:1, and teachers provided weekly, 1.5 hour home visits for all participants. The HighScope Perry Preschool model encourages active learning, where children plan their own activities, carry them out, and reflect on them. Adults arrange the classroom to foster learning in various areas and coach children as the children plan activities, solve problems, and think through their ideas1, 2.

  • Reduced crime

  • Reduced teen pregnancy

  • Increased healthy behaviors

Evidence of Effectiveness

There is some evidence that the HighScope Perry (HSP) preschool model increases children’s academic achievement1, 3, 4, 5, 6, 7. However, additional evidence and replication on a larger scale is needed to confirm effects.

Research following one cohort of HSP preschool students through age 50 indicates that participants have greater academic success, increased employment and earnings, reduced childhood antisocial behavior, and lower rates of crime and incarceration in adulthood than their peers6, 7. These students also have healthier behaviors such as increased use of preventive health care and reduced alcohol and drug use relative to their peers8, 9, 10. Girls, in particular, are much more likely to complete high school1, and are less likely to give birth before age 19 than non-participating peers5. HSP boys are arrested less often as teenagers and adults, and get in fewer gang fights than non-participating peers1. Positive intergenerational spillover effects have been identified in the children of HSP students compared to those of nonparticipants, including fewer school suspensions, higher levels of education and employment, and lower levels of participation in crime11.

The HSP approach also includes child-directed free play under the supervision of staff emphasizing the cultivation of interpersonal skills, which has been shown to improve healthy development, especially social development12. The original HSP preschool program used deficit-based framing at the administrative level, though some or most teachers subscribed to asset-based framing13, 14. Additional research is needed to determine which HSP preschool features or combination of features (e.g., teacher training, curriculum, child assessment, services offered, etc.) support positive outcomes15.

A cost benefit analysis indicates Ypsilanti’s HSP preschool yielded an average societal benefit of $6.60 for every dollar invested16, almost a 7 times return on investment (ROI)6. Another analysis finds the benefit-cost ratio is 9 to 1, when accounting for the cumulative benefits of increased labor income, reduced crime and costs to the criminal justice system, improved health and healthy behaviors, and the positive spillover effects on participants’ families17.

Equity Analysis

Potential to decrease disparities: Supported by some evidence

There is some evidence that the HighScope Perry (HSP) preschool model has the potential to decrease disparities in educational attainment between Black children from families with low incomes and white children from families with higher incomes by increasing participants’ academic achievement1, 3, 4, 5, 6, 7. Generally, studies of preschool education programs have shown that gains in cognitive skills and academic achievement are larger for students from families with low incomes than for students from families with high incomes19, 20. A benefit-cost analysis of the HSP preschool project shows multi-generational benefits for participants and their children, as well as large, positive net gains for society17. However, additional evidence and larger scale implementation are needed to confirm effects on disparities.

Historical Context

Education disparities in the United States are shaped by many factors, including a long history of racial segregation in schools. In 1954, the US Supreme Court ruled in Brown v. Board of Education that racial segregation in public schools was unconstitutional21, but segregation remains a persistent problem22. Some legal battles over school segregation were not resolved until 201623 and structural barriers, such as continued residential segregation, play a significant role in maintaining school segregation22.

National interest regarding preschool as an intervention to address educational disparities was high in the 1960s when the HighScope Perry (HSP) preschool program was conducted13. The federal Head Start program began in 196524 and the first nationwide education inequality report, known as the Coleman Report, was mandated by the Civil Rights Act of 196425. Educational disparities across racial and economic groups were highlighted as a concern by teachers, administrators, and policymakers during this period with the Civil Rights movement and the “war on poverty”26. Since then, evidence from the HSP preschool model has been influential in garnering support for more recent early childhood education models.

Equity Considerations

  • What knowledge, skills, and abilities do families and children with low incomes in your community already have? How can your local preschool program be structured to highlight and build on those strengths?
  • How could your community increase access to high quality preschool programs for children from families with low incomes? For students identifying as a racial or ethnic minority?
  • Which populations in your community have lower rates of preschool attendance? What outreach activities might help reduce those disparities?
  • What educational disparities exist in your community? How do systemic factors such as disproportional school discipline rates and residential segregation contribute to these disparities?

Implementation Examples

The original HighScope Perry Preschool is no longer operating. HighScope now maintains a demonstration classroom in Ypsilanti, Michigan that features the HighScope curriculum1, 18. The HighScope curriculum, built on the HighScope Perry Preschool model, is used in Head Start programs, as well as various public pre-kindergarten programs, and private preschools across the United States. This curriculum continues to evolve based on ongoing research18.

The HighScope Educational Research Foundation also offers training, material development, and curriculum assistance to preschool programs around the country1
