International School of San Antonio

Three-Language School on Callaghan Road

International School of San Antonio (ISSA) teaches kids ages 3–12 in Spanish, Mandarin Chinese, and French. Alongside its regular school year program, ISSA runs weekly language immersion camps during spring and summer breaks — a popular option for families who want intensive exposure without year-round commitment.

Language Camps and Classes

Camps and after-school tracks let kids immerse in a target language while doing kid-friendly activities:
- Spanish immersion (ages 3–5 and 6+)
- Mandarin Chinese immersion
- French immersion
- Themed weeks including Around the World, Cooking, and STEAM
- Saturday classes during the school year

What's Included

• Half-day ($225/week) or full-day ($450/week) camp options
• Optional before care and lunch supervision
• Sports, cooking, art, and science experiments in the target language
• Small age-grouped cohorts
• Sibling, ISSA student, and Saturday discounts

Experience

ISSA fits families seeking genuine language immersion in a school setting — either as full enrollment or through intensive camp weeks. Kids spend the day playing, creating, and exploring entirely in the target language, which builds confidence faster than traditional once-a-week lessons.
