What has been the biggest, fastest expansion of public education in American history? Preschool. A new radio documentary by American Radio Works, Early Lessons, examines how early child care and education are changing public schools.
The results from the Perry Preschool study has also changed how we define the success of a program. The results from the project indicated that while the IQ score gains can "fade out" over time, the program participants benefited in other ways not measured by IQ - more likely to own a home, have a savings account, stay out of prison, have a higher paying job and more. These other benefits have an even greater impact on the community as a whole, beyond an individuals supposed IQ score, this is where the return on investment can be measured.
The Perry Preschool Project continues to be a cornerstone piece of research that influences public policy in Minnesota and around the nation.
The challenge is taking the good pieces of the Perry Preschool and replicating them in cost effective ways. Pieces like the quality of the program and the developmental appropriateness of the curriculum are more easily measured and can be replicated. The more challenging thing is to replicate the activities and lessons that gave the children the skills and motivation to continue to do well in school and later in life.
