San Antonio, Texas is among several cities that have opted for investing in preschool education, in addition to state mandates, much like the Boston pre-K program (National League of Cities, 2012). San Antonio is unique because the city has funded the program through a voter-approved 1/8 cent increase in local sales tax rates starting April 1, 2013. The program, called Pre-K 4 SA, serves many children who are at risk for falling behind their peers and for lacking in kindergarten readiness, with the goal of increasing early childhood quality and school readiness across the city of San Antonio (see Figure 1 for the Pre-K 4 SA theory of change). One of the three main components of the Pre-K 4 SA program theory--educating children in created centers (referred to as Pre-K 4 SA Centers in the visual theory of change)--began during the 2013/14 school year and served nearly 700 children in the first two Pre-K 4 SA Centers (North and South Centers). The past school year (2014/15) saw an increase to more than 1,500 children served across all four Pre-K 4 SA Centers. Pre-K 4 SA estimates it will reach full capacity (serving 2,000 children annually) by 2016/17 in the four Centers across the city. The purpose of the current report is to present evaluation findings from the second year of the Pre-K 4 SA program. Investigations included: 1) descriptive information concerning child attendance, parent engagement, teacher professional development, and classroom and teacher quality information; 2) fidelity of implementation results for the two active Centers in their second year of operation; and 3) outcome analysis results of the Teaching Strategies Gold assessment system (GOLD) which is the primary outcome of interest at the end of the pre-K year.
