Preschool Attendance and High School Graduation Rates The Perry Preschool Project was created in the early 1960s by David Weikart in Ypsilanti, Michigan.

One hundred and twenty three African American children were randomly assigned to one of two groups: One group enrolled in the Perry Preschool, and one did not enroll.

Follow-up studies were done for decades to answer the research question of whether attendance at preschool had an effect on high school graduation.

The table shows whether the students graduated from regular high school or not. Students who received GEDs were counted as not graduating from high school.

This table includes 121 of the original 123. This is a test of homogeneity, because the students were randomized into two distinct samples.
