Building on our previous work, we explore the longer-term effectiveness of a high-quality, large-scale, public-school based pre-K program. We find that 7th grade students who participated in the Tulsa Public Schools pre-K program years ago score higher on state mathematics tests, are more likely to enroll in honors courses, and are less likely to have been retained in grade than other students. We conclude that the effects of a high-quality pre-K program diminish but do not disappear. (author abstract)
