About
International School of San Antonio on Callaghan Road
The International School of San Antonio runs a Saturday language-immersion program on Callaghan Road in northwest San Antonio. Native-speaking instructors teach through gestures, modeling, real-life objects, and pictures rather than translation, so children acquire the language naturally in small groups of four to six on Saturday mornings.
Language Programs
Weekly immersion classes serve children roughly ages 3 to 12, split into a 3-to-6 group and a 6-to-12 group. Languages offered:
- French
- Mandarin Chinese
- Spanish
- Russian
- Spring and summer week-long immersion camps with arts, crafts, cooking, storytelling, and singing
What's Included
- Native-speaking instructors
- Small classes of four to six students (about a 6:1 ratio)
- Saturday-morning sessions from 9 to 11 with a snack break and outdoor free play
- Full-semester enrollment with sibling and military discounts
Experience
The Saturday format suits families who want structured immersion without committing to a full day school, and the four-language menu including less-common Russian is unusual for the San Antonio market. Best fit for children 3 to 12 whose families want native-speaker exposure at a low student-teacher ratio, with optional camps extending the language into school breaks.
