q3 · i? · review · r3

The WWC report summarizes the DHHS ACF (2010) randomized controlled trial, in which children were randomly assigned to be offered Head Start or a comparison group. The average improvement index for general reading achievement was +13 percentile points (range +12 to +14), and the WWC confirmed a "statistically significant and positive effect of Head Start" on PELS ratings.

"The authors reported, and the WWC confirmed, a statistically significant and positive effect of Head Start on children’s PELS ratings for both the 3-year-old and 4-year-old cohorts at the end of the intervention year."
