Mission Statement

St. Louis Language Immersion School (SLLIS) is the only K-8 not-for-profit dual language immersion public charter school in the St. Louis region with offerings of 3 language programs (Chinese, French and Spanish) and Middle School Program whereby students are taught a second language and 50% of the core subjects are in the focus language with the goal of academic biliteracy. SLLIS' mission is to provide a bilingual, culturally responsive, transformational education that enriches the children of St. Louis City. SLLIS’ purpose is to dismantle systems of oppression by creating a just, equitable and inclusive school, St. Louis community, and world. Core Values include: Providing an accessible and rigorous bilingual education; Listening to and engaging all voices; Committing to equity, anti-racism and cultural competency; Reflecting on and responding to data throughout our school; Celebrating mission moments, both big and small. SLLIS provides quality and accessible education and resources for all students, many who fall in to the guidelines of under-represented and under-served. 66% of students qualify for Free and Reduced Lunch. All St. Louis City residents are eligible to attend SLLIS for free. Enrollment for the 2023-2024 school year is 402 students in K-8 and 14 Pre-K students. Beginning with this current school year, new enrollment initiatives have been put in to place: a new SLLIS run Dual Language Spanish Pre-Kindergarten and the "Bridge to French" program. There is no other public charter school with the size of SLLIS’ student population anywhere in this region that provides busing for all students to and from school daily.
