San Antonio Stone's Best Private Schools

Stone Oak parents don’t just compare schools; they compare philosophies. You’ve got Acton Academy’s self-paced, grade-free experiment on one end and San Antonio Independent School’s silent, hyper-structured rigors on the other.

Between them sits everything from Spanish Grove’s bilingual toddler Montessori to Saint Thomas More’s quiet, reliable tradition. We toured all of them, from the chapel halls near Huebner Road to the tidy classrooms off West Avenue.

One campus offers cooking class and CCS tuition; another demands a five-year family commitment. The choice is a personality test, not just a spreadsheet.

See which one your kid—and your sanity—survives.

International School of San Antonio

The International School of San Antonio brings a global lens to Stone Oak. The premise is simple: your child will learn in a multilingual, multicultural environment from day one. The curriculum is international in scope, and the teaching staff reflects that breadth. Classrooms are active, and students are pushed to think beyond borders. The school is smaller than some competitors, which allows for close teacher-student relationships. Parents who want their children to grow up with a worldly perspective will find this appealing. It is not the cheapest option, and the rigor is real. But if global readiness is the goal, this school delivers.
