Investigating if high-quality kindergarten teachers sustain the pre-K boost to children's emergent literacy skill development in North Carolina.

This study tested the hypothesis that high-quality kindergarten teachers sustain and amplify the skill development of children who participated in North Carolina's NC Pre-K program during the previous year, compared to matched non-participants (N = 17,330; 42% African American, 40% Non-Hispanic White, 15% Hispanic; 51% male; Mage = 4.5 years at fall of pre-K). Kindergarten teacher quality was measured using a "value-added" approach. NC Pre-K participants outperformed non-participants in the fall of kindergarten (ß = .22) and 11% of this boost remained evident by the spring of kindergarten. Higher value-added teachers promoted the skill development of all children (ß = .30 in the spring) but did not differentially benefit the skill development of former NC Pre-K participants compared to non-participants.

Effects of North Carolina's Pre-Kindergarten Program at the End of Kindergarten: Contributions of School-Wide Quality.

The positive effects of pre-kindergarten (pre-K) programming may be enhanced in later grades for children who subsequently experience high-quality educational environments in elementary school. The current study tested this hypothesis in relation to the effects of North Carolina's NC Pre-K program on child outcomes at the end of kindergarten, including language, literacy, mathematics, and working memory. Measures of elementary school quality were examined as moderators of the NC Pre-K effects, including school-wide academic proficiency and school-wide growth in academic achievement. We found no reliable effects of NC Pre-K participation for children attending elementary schools with average levels of quality. However, the positive effects of NC Pre-K participation on language and working memory skills were evident for children attending elementary schools with higher levels of academic proficiency and academic growth, respectively. No evidence of moderation was found in relation to literacy and mathematics skills.
