School Notes
- Beginning with three-year-olds, our comprehensive program offers well-rounded rigorous education that meets and exceeds Texas state education standards and is delivered in either Mandarin Chinese, French, or Spanish. Instruction in English is added in Pre-K4 and is increased in elementary school to enable full bi-literacy. A third language of choice, music, arts, science, and physical education are also included in the curriculum. Small class sizes allow for more interaction with and attention from the teacher. Children will graduate ISSA as biliterate global citizens and will be ready for middle school in any of the two acquired languages.
- Join us on Saturday, February 8, 2025 from 10am-11am to learn more about all the amazing opportunities ISSA has to offer!

School Reviews
5 4/8/2022
This is a fantastic school. My son has thrived since coming to this school a few months ago. His Spanish is improving, as well as his motor skills with drawing and pre-writing. He brings home the best art projects. The daily pictures and videos show how excited he is to be there and how much he is concentrating on his work. I love that the school also offers a mini-festival on one Saturday each month. We love this school and he's definitely staying for elementary school.
