St. Louis Language Immersion School (SLLIS) is a public charter school located in downtown St. Louis, Missouri, serving students from Kindergarten through eighth grade. The school operates as an IB World School, utilizing the International Baccalaureate Primary Years Programme and Middle Years Programme. What makes the school unique is its total immersion model; families choose one of three language tracks—French, Spanish, or Chinese—and students receive the majority of their daily instruction in that target language.
The campus includes dedicated spaces for science, technology, and the arts, supporting a curriculum where subjects like mathematics and social studies are integrated with language acquisition. A signature initiative is the school's commitment to biliteracy, aiming for students to be proficient in both English and their chosen immersion language by graduation. As a public institution, it provides free tuition and bus transportation for city residents, ensuring the program is accessible to a broad community.
