The aim of this study is to run a longitudinal, ten year experimental study studying the effects of preschool attendance on long-term academic performance throughout elementary school. This study will sample 500 students from the Kalamazoo, Michigan community and observe their standardized test scores as well as their behavioral and social development as they progress through elementary school. I hope to discover the long-term impacts of attending pre-K programs on children in order to give educators and administrators a greater insight on how they should prioritize pre-K education in their schools.
