The study examined whether exposure to Kindergarten PAVEd for Success, a vocabulary instruction program, improved expressive vocabulary of kindergartners. The study analyzed data for nearly 1,300 kindergarten students in 64 schools serving predominantly rural and high poverty youth in the Mississippi Delta region and surrounding areas. Kindergarten students in schools using Kindergarten PAVEd for Success as a supplement to regular literacy instruction performed better than kindergarten students in control schools on expressive vocabulary. The estimated effect size was 0.14, a statistically significant result. The authors reported that students who received Kindergarten PAVEd for Success instruction were one month ahead in vocabulary development at the end of kindergarten compared with students in the control group. The research described in this report meets What Works Clearinghouse (WWC) evidence standards. (Contains 2 footnotes.)
