The question addressed in this study is whether the school readiness impacts found for the CAP Head Start participants in kindergarten did or did not persist as the children progressed through school. We compared the Head Start participants (2005-06 cohort) to children who attended neither a CAP Head Start nor a school-based pre-K classroom. Most of the children in this follow-up study were in 8th grade, but we also included students who were retained in grade once and were thus 7th graders. (author abstract)
