Two-Way Bilingual Immersion 90/10 Model

Osborn School offers students the unique and exciting opportunity of learning to communicate in two languages, Spanish and English. Our goal is to educate students who are bilingual and biliterate and enable them to meet the challenges of a global society. Students acquire the skills to read, write, speak, listen, and think in two languages.  The development of fluency and literacy in two languages requires several years of continuous participation in the immersion program. Enrollment occurs primarily at the kindergarten level.  In the Osborn School Two-Way Immersion Program, Spanish is used as the language of instruction throughout the primary grades.  English is introduced gradually into the curriculum.


If you are interested in seeing this exciting program in action, you may visit our school on Immersion Visitation Days, 9:00 AM the first Tuesday of each school month.
