Seattle Pre-K Program Evaluation


October 8, 2018
AssessmentOutcomesState & Local

The National Institute for Early Education Research at Rutgers University and Cultivate Learning, at the University of Washington, have conducted evaluations of the demonstration phase of the Seattle Preschool program. Evaluations assessed preschool quality and measured children’s gains in receptive vocabulary, literacy, math and executive functions.

The City of Seattle is in the final year of a four-year demonstration phase for its Seattle Preschool Program. The program was established by voter approval on November 4, 2014 of a four-year, $58 million property tax levy to provide “accessible high-quality preschool services for Seattle children designed to improve their readiness for school and to support their subsequent academic achievement.” The city of Seattle’s Department of Education and Early Learning (DEEL) launched SPP in the 2015–16 school year and has been expanding every year since.

The four-year demonstration phase of SPP has three purposes. The first is to demonstrate that the approved structure is viable. The second is to develop a community infrastructure to improve the quality of preschool programs. The third is to create norms and a process to support continuous quality improvement (CQI) through evaluation. Results from evaluation during the demonstration phase will inform improvements in these efforts.

Before commencement of this demonstration phase, the evaluation team conducted a thorough review of the research on evaluation, supplemented with interviews of key leaders in program design and improvement. Based on this review the team recommended, among other efforts, an impact evaluation that collects information on students’ learning and development.

Reports below present findings from year one (2015-16), year two (2016–17) and year three (2017-18) from the impact evaluation, focusing on classroom quality and children’s learning. The report includes information on the children served, children’s learning and development during the school year, and program quality across the three years of SPP so far. It also looks at specific subgroups of children and classrooms and examines associations between SPP children’s learning gains and their classroom experiences including observed quality.

In 2017–18 SPP grew to 48 classrooms and 13 family child care providers from 32 classrooms in the prior year. SPP quality continued to improve and now reaches levels associated with strong gains in children’s learning and development.  We recommend that SPP build on its success by seeking further improvements in the quality of instruction with particular attention to language and literacy, integration of content across domains in children’s activities, and supports for sustained, reflective thinking as well as personal care routines that contribute to health.
