The Kamehameha Schools’ Pauahi Keiki Scholars (PKS) program provided need-based vouchers or scholarships for three- and four-year-olds to attend eligible private preschools. The evaluation of this program reviewed the implementation of the PKS program and assessed the program’s impact on children, families, and preschools. Data were collected from site visits (through interviews and the use of classroom assessment tools), parent surveys, and review of program and school level documentation. Evaluators also analyzed achievement data from KS staff. The results suggested that families were quite satisfied and that most preschools were having a noticeable impact on student performance as measured by a standardized test (i.e., PPVT). The multiyear evaluations provided sound recommendations and feedback to program administrators for future program planning and improvement.
