Fact Sheet: The Abbott Preschool Program Longitudinal Effects Study (APPLES)

Beginning in the 2005-2006 school year, the seventh year of implementation of the high-quality pre-K program in New Jersey's Abbott districts, NIEER began a longitudinal study to measure learning gains from participating in Abbott pre-K.  At the time the study began, quality had risen but not yet to its current level, and 40,500 3- and 4-year-old children were served. This fact sheet presents key takeaways from NIEER's longitudinal study of the program quality and child outcomes.
