With the academic rigor of kindergarten increasing, it is imperative that children come to kindergarten with a foundation that will allow them to be successful in the kindergarten classroom. This mixed-method research project sought to explore the impact of participation in an early childhood on the academic achievement in the areas of literacy and math for kindergarten students. The population used consisted of kindergarten students in 2 different schools. Kindergarten readiness was measured using a Kindergarten Readiness test, and academic achievement was measured using STAR scores from screeners given in October and January. Statistical significance was found in the areas of Kindergarten readiness and academic readiness in the areas of literacy and math.
