Dual Immersion Programs implement a two-way dual language model of instruction, serving native speakers of English alongside native speakers of Spanish. Students from both language groups attend class together, learn from each other and receive academic instruction in both languages. Bixby follows a 90/10 DI program model where beginning in Kindergarten, 90% of instruction is in a target language and 10% of instruction is English. The percentage of instruction in English increases in each subsequent grade until reaching a 50/50 distribution in 4th through 8th grade.
