FLACS was founded in 2001 by the Latino Pastoral Action Center (LPAC) under the vision of Reverend Raymond Rivera. The founding team developed a vision for a school that would serve the students of the community, primarily immigrant students and English language learners. The school would create opportunities for success for all students, no matter their primary language, ethnicity, or socio-economic status. In 2012 and 2014, replication elementary schools FLACS II and FLACS III opened. In 2019, FLACS completed work on a new campus, FLACS MS, which is part of the FLACS II charter, but educates all FLACS middle school scholars from each of the three elementary schools.
FLACS continues to expand and will open FLACS HS in Fall 2022. This campus will serve 700 scholars in grades 9-12.
