Throughout the United States, state governments are allocating millions of dollars to support Voluntary Pre-Kindergarten (VPK) programs. Recent research has indicated that students that participate in VPK demonstrate higher academic achievement scores across a number of subject areas. Moreover, VPK participants are more likely to enter primary school on grade level, which in turn leads to a reduction in grade retention. Studies have indicated that although all students that participate in VPK programs benefit from such programs, minority students and students that come from low-socioeconomic backgrounds benefit at an even higher level. The intent of this study was to determine to what extent, if any, a VPK program within a large, suburban school district impacted the academic achievement and kindergarten preparedness of participants in comparison to students that did not participate in the VPK program offered by the district. To measure the impact, student scores on the 2006-2007 Florida Kindergarten Readiness Screener (FLKRS) were compared through the use of an independent samples t-test. The same students had their 3rd grade Florida Comprehensive Assessment Test (FCAT) Reading and Mathematics scored compared as well. Two groups were compared against one another. The control group was a group of students that did not participate in the VPK offered by the school district. The treatment group was the group of students that participated in the district offered VPK. The results of each of the independent sample t-tests conducted determined that there was not a statistically significant different in either student preparedness or student academic achievement between the VPK participant group and the non-participant group.
