The Effects of Universal Pre-Kindergarten Programs on Socioeconomic Achievement Gaps
Quick fact
Studies of universal pre-K programs, such as in Oklahoma and Boston, have shown substantial gains in school readiness, with disadvantaged children often making greater strides, effectively narrowing the achievement gap at school entry.
Why this is interesting
Imagine two children entering kindergarten: one has had years of enriching experiences, the other has not. Could a single year of universal preschool close that gap?
