Strategies with this rating are likely to work, but further research is needed to confirm effects. These strategies have been tested more than once and results trend positive overall.

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.

Expected Beneficial Outcomes (Rated)

  • Increased academic achievement

Other Potential Beneficial Outcomes

  • Increased high school completion

  • Increased earnings

  • 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. 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.

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 development10. 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 outcomes11.

A cost-benefit analysis indicates Ypsilanti’s HSP preschool yielded an average societal benefit of $6.60 for every dollar invested12, almost a 7 times return on investment (ROI)6.

Impact on Disparities

Likely to decrease 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, 13. 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 research13.

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