1. International School of San Antonio
Website: https://issatx.org/
Address: 6739 Callaghan Road
Contact: +1 210 920 4315
Hours:
- Monday – Friday: 7 AM – 5 PM
- Saturday: 9 AM – 11 AM
International School of San Antonio excels at delivering a comprehensive multilingual curriculum. Its rigorous language immersion program allows native-speaking teachers to teach students in Mandarin Chinese and French.
A close friend of mine enrolled her son here last year, and I was genuinely amazed to hear him speaking conversational French confidently after just a few months.
Notably, it has a low 6:1 student-to-teacher ratio, ensuring highly personalized support.
Plus, the faculty represents a wide range of nationalities, which brings authentic cultural experiences directly into the classroom.
While the school offers a strong academic foundation, it currently serves students only through fifth grade. So, parents looking for a continuous path through middle and high school will eventually need to plan for a transition to another school.
2. Kent International Academy

Address: 1323 Brookstone

Hours: Monday – Friday: 7 AM – 6 PM
Raising culturally aware citizens starts early, and Kent International Academy strongly emphasizes a trilingual, bicultural curriculum that supports both intellectual and character development.
On top of that, the school combines social constructivist theories with a multiple intelligences approach, encouraging children to explore ideas actively through hands-on play.
The administration also places great value on social-emotional learning, with daily routines designed to build empathy and respect alongside traditional academics.
At the same time, parents play an active role in this collaborative model, which makes the campus feel like a welcoming extension of the home.
One drawback to consider, however, is the limited age range, as the school’s current programs focus mainly on infants and preschool-aged children rather than older students.
3. International Children’s Academy

Hours: Monday – Friday: 7 AM – 6 PM
Finding childcare that balances nurturing supervision with strong academics can be challenging, but International Children’s Academy does this well through its bilingual environment.
The school holds a four-star ranking in the Texas Rising Star program, which shows that its Spanish and English immersion classes go beyond standard state childcare regulations.
Class sizes are intentionally kept small, allowing experienced educators to create individualized lesson plans for children from infancy through age five.
I recently spoke with a colleague who sends her daughter there, and she praised the school’s unique enrichment activities, including classical music integration and weekly juicing projects.
One downside to keep in mind, however, is that the language focus is limited to Spanish, which may not suit families looking for a wider range of language options.
Plus, the curriculum ends at the pre-kindergarten level, so families will need to begin exploring other primary school options fairly early.
4. Immersion Montessori Academy

Address: 11102 West Avenue
Contact: +1 210 272 0658
Hours: Monday – Friday: 7:30 AM – 5:30 PM
Blending independent exploration with dual-language proficiency isn’t easy, but Immersion Montessori Academy does this well through its bilingual Spanish immersion environment.
Lower elementary classes are limited to 15 students, allowing teachers to tailor lessons to each child’s needs. The school also prioritizes safety with restricted building access and fully certified staff trained in emergency procedures.
Beyond core academics, students benefit from year-round programming that includes cultural cooking classes and themed summer camps designed to strengthen fine motor skills.
On the downside, the academy doesn’t hold formal international accreditations such as the International Baccalaureate program.
Plus, the school serves only early childhood and lower elementary grades, so older students will eventually need to transfer to another school.
5. Fusion Academy San Antonio
Website: https://www.fusionacademy.com/campuses/san-antonio/
Address: 227 N Loop 1604 E, Suite 100
Contact: +1 210 510 0203
Hours: Monday – Friday: 7:30 AM – 7:30 PM
Transitioning into a new educational system often requires a great deal of flexibility, and Fusion Academy San Antonio meets that need through its highly personalized one-to-one learning environment.
Each class pairs one student with one teacher, allowing instruction to move at the exact pace of the child. The administration also prioritizes emotional well-being first, building trust and motivation before introducing more demanding academics.
Plus, students complete all assignments on campus in dedicated homework spaces, which helps eliminate evening struggles over schoolwork at home. The schedule is also highly adaptable for mid-year relocations.
However, because instruction is centered on one-to-one or small-group sessions, the campus doesn’t offer the large multicultural student body or traditional sports teams often associated with international schools.
It’s also worth noting that the school doesn’t provide specialized on-site preparation for major standardized university admissions exams.
