Back-to-school season has arrived across Greater San Antonio, but not every school district begins classes on the same day. Depending on where you live, students may return anytime from early to late August.

Whether your family has lived in the area for years or you are relocating to San Antonio because of a military PCS, a new job or a change in housing, knowing the correct school calendar can make the transition much easier.

2026 Greater San Antonio School Start Dates

Here are the published first-day dates for several of the largest school districts in the Greater San Antonio region.

Some districts operate specialized, early-college, year-round or extended-year campuses that follow different calendars. For example, NEISD lists separate calendars for its traditional, ACE and Castle Hills programs. Parents should confirm the first day directly with their child’s campus.

Moving to Greater San Antonio During the School Year

Greater San Antonio includes many independent school districts, and attendance boundaries do not always follow city limits or mailing addresses. Two homes with the same city name or ZIP code can sometimes be assigned to different districts or campuses.

Before making a home-buying or leasing decision, use the district’s official school locator and contact the district to verify the attendance assignment. Real estate listing information can be a helpful starting point, but school boundaries should always be independently confirmed.

School Registration Checklist for Relocating Families

Every district has its own enrollment requirements, but families are commonly asked to provide several of the following documents.

Requirements may differ for families living in temporary housing, purchasing new construction, staying with relatives or awaiting a military move. Contact the district enrollment office if your family does not yet have the customary proof-of-residency documents.

Back-to-School Tips for Military Families Moving to JBSA

A PCS to Joint Base San Antonio may place a family near Randolph AFB, Fort Sam Houston or Lackland AFB. Each installation is surrounded by several communities and school districts, so commute time and school assignments should both be considered during the home search.

Start collecting school records before the move

Request copies of transcripts, report cards, immunization records, special program documentation and withdrawal paperwork before leaving your current duty station.

Ask about enrollment while living in temporary housing

If you are staying in temporary lodging while searching for a home, speak with the district about its enrollment and residency policies before assuming which campus your child will attend.

Verify the campus before choosing a property

Never rely solely on a real estate advertisement, map or ZIP code to determine school attendance. Confirm the specific address with the appropriate school district before making a final housing decision.
