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 operated on various campuses for many years.
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.
In December 2018, the SLLIS Board of Directors purchased SLLIS' current facility at 1881 Pine Street, and all SLLIS programs moved to this location.
