The program offers a comprehensive early childhood initiative aimed at changing the education and workforce trajectory of San Antonio in one generation through high-quality pre-kindergarten education for 4-year-olds in the city. Pre-K 4 SA is free for qualifying students and also accepts tuition-paying students. The application process serves families of 4-year-olds across San Antonio on a first-come, first-served basis. Parents of eligible students can apply online by completing the entire application process or by calling the enrollment hotline. Children who live in partner school districts are eligible, even if that residence lies outside the San Antonio city limits.
