Preschool in San Antonio is not one thing. It is the city's free publicly funded pre-K under Texas Education Code Section 29.153 free public Pre-K for eligible 4-year-olds; it is the private preschool feeder for a college-prep K to 12; it is the pre-K room inside the daycare your child has attended since infancy; it is the half-day cooperative two mornings a week. This roundup covers all four lanes across Alamo Heights, Olmos Park, Terrell Hills, Monte Vista, King William, Southtown, Stone Oak, the Pearl District, the Medical Center, Castle Hills, Helotes, Boerne, and the broader Loop 1604 corridor, the 2026 cost picture, and what to ask on a tour.
All picks are editorial. We have not been paid by any program below. For the full city overview, including subsidies, public pre-K, and licensing rules, see our San Antonio daycare guide.
Preschool typically refers to the 3-to-5-year-old years, regardless of whether the program operates inside a daycare center, a stand-alone preschool, or a public elementary school. The distinction from "daycare" is partly age (preschool is 3 and up; daycare often spans infant through pre-K) and partly emphasis (preschool foregrounds school-readiness skills; daycare emphasizes care across all ages).
In San Antonio, preschool families have three competing options. The first is the city or state's publicly funded pre-K, which under Texas Education Code Section 29.153 free public Pre-K for eligible 4-year-olds is free for eligible 4-year-olds (and many 3-year-olds). The second is private preschool, which ranges from neighborhood co-ops at $700 a month for part-day to college-prep independent schools at $40,000 a year for kindergarten-bound 5-year-olds. The third is the pre-K classroom inside a full-day daycare center, which is the right fit when families need full working-day hours and a continuous setting from infancy.
The choice depends on schedule, budget, and what comes next. Our daycare vs. nanny vs. preschool pillar lays out the comparison in detail; our Texas pre-K explained piece covers the publicly funded path. For families committed to a private preschool feeding an independent K to 12 school, admission timelines in San Antonio run early and competitive.

Pre-K 4 SA is the city of San Antonio's voter-approved free pre-K program, funded by a 1/8-cent sales tax and renewed by voters in 2020. The program operates four Education Centers (East, West, North, South) and contracts with partner providers across Bexar County. Seats are free for eligible 4-year-olds.

San Antonio Independent School District operates one of the larger free public pre-K systems in Texas, with classrooms at most elementary campuses. Under Texas Education Code Section 29.153, pre-K is free for all 4-year-olds; 3-year-olds qualify on a means or status basis. SAISD's Office of Early Childhood handles enrollment. A meaningful free option for SAISD-resident families.
Saint Mary's Hall is one of San Antonio's most established independent K to 12 schools. The Lower School includes pre-K (Montessori-influenced) and kindergarten, feeding the school's elementary sequence. Tuition is at the top of the city range; financial aid is meaningful. Admission to the K to 12 sequence is competitive and applications open 12 to 18 months in advance.
Keystone School is an independent K to 12 with a small but distinctive Lower School beginning at pre-K (Kindergarten-prep). The school's identity is academic and gifted-focused. Tuition is at the upper end of the city range; the pre-K and kindergarten classes are small. A meaningful option for families committed to a K to 12 independent track with an academic emphasis.
TMI Episcopal operates a Lower School beginning at age 3 (Pre-K3) through 12th grade. Religious content is moderate and Episcopal in tradition. The pre-K and kindergarten classrooms feed the school's elementary sequence. Tuition is at the upper end of the North Side range; the campus and outdoor space are extensive.
Family Service Association is one of the primary Head Start grantees in Bexar County, operating sites across the city. Slots are income-eligible and free. The single best option for families who qualify on income and want a research-based pre-K experience at no cost. Several sites operate dual-language Spanish-English classrooms.
San Antonio Academy is one of the oldest independent boys' schools in Texas, with a Montessori-influenced Lower School beginning at age 3. The pre-K and kindergarten feed the school's K to 8 sequence. Tuition is at the upper end of the city range. A meaningful option for families committed to an all-boys independent track.
Northside ISD and North East ISD both operate large free public pre-K systems at elementary campuses across the North and Northwest sides of the city. Eligibility follows the Texas Section 29.153 standard. A practical option for families outside the SAISD boundary; both districts operate dual-language seats at select campuses.
Trinity Christian Academy operates a K to 12 evangelical Christian school with a pre-K and kindergarten feeding the elementary sequence. Religious content is consistent and evangelical Protestant in character. Tuition runs in the middle of the city range. Our daycare vs. nanny vs. preschool pillar is worth reading if you are weighing private K to 12 feeders against free public pre-K.

Yes, for eligible children. San Antonio operates publicly funded pre-K through Texas Education Code Section 29.153 free public Pre-K for eligible 4-year-olds, plus the city-funded Pre-K 4 SA program (voter-approved 1/8-cent sales tax), delivered by San Antonio ISD, North East ISD, Northside ISD, Alamo Heights ISD, Judson ISD, and the Pre-K 4 SA Education Centers, which is free for all 4-year-olds and free for income-eligible 3-year-olds (eligibility varies). Enrollment runs through the city or district application each year. Our Texas pre-K explained piece covers the details.
Preschool typically refers to the 3 to 5 year age band with an emphasis on school-readiness; daycare often spans infant through pre-K with an emphasis on care across all ages. Many full-day daycare centers operate a preschool room as part of their continuum. Our daycare vs. nanny vs. preschool pillar walks through the comparison.
For the most-applied-to private preschools and K to 12 feeder schools in San Antonio, applications open 12 to 18 months before the intended start. Less competitive programs and neighborhood co-ops accept applications closer to the start date. Our when to start a daycare waitlist guide covers the timeline.
Both work; the choice depends on the family's schedule and the child's stamina. Half-day suits children who are still napping mid-day and families with at least one non-working caregiver. Full-day suits dual-working families and children who are ready for a longer school-style day.
Most do not. Public pre-K is free for eligible families; Head Start is free for income-eligible families. Private preschools occasionally offer need-based financial aid, particularly at independent schools. Texas Workforce Commission Child Care Services (CCS), administered locally by Workforce Solutions Alamo typically applies to licensed daycare and family child care, not to private preschool tuition.
