Riverview's Spanish immersion program, Riverview International Academy, began in 2006. It is a one way immersion program in which students receive 100% instruction in Spanish in Kindergarten and first grade. Formal English instruction begins in 2nd grade with approximately 20% and increases incrementally to 50% by 5th grade. Spanish Immersion students receive enrichment in Mandarin in grades K-2 and formal instruction of approximately 120 minutes per week in grades 3-5. Because 100% of instruction is in Spanish, parents are expected to read to their child in English daily and support English instruction at home.
