In 2007, Rhonda Broussard founded St. Louis Language Immersion School (SLLIS), a federal non-profit charter management organization funded primarily by the Missouri Department of Elementary and Secondary Education and guided by a agreement with SLLIS’ primary sponsor, the University of Missouri-St. Louis.
Under Broussard’s leadership, The French School and The Spanish School opened in 2009 for kindergarten through fifth grade. The Chinese School, also serving K-5, opened in 2012. The International School, for sixth through eighth grade students receiving a bilingual education in French or Spanish, opened in 2014.
In January 2017, the Board of Directors voted to reconfigure the four schools into one K-8 school, running three different language immersions programs in Chinese, French and Spanish. SLLIS is on two campuses: K-6 Spanish at the Papin Campus, and K-6 Chinese and French plus grades 7-8 at the Marine Campus.
In February 2018, the SLLIS Board of Directors adopted the Gomez and Gomez Dual Language Enrichment Model, further structuring how SLLIS goes about immersion instruction.
