The Hoboken Dual Language Charter School (HoLa) utilizes the 90-10 immersion approach to provide a robust academic curriculum through instruction in both Spanish and English, with a range of opportunities for creative expression and experiential learning. Research demonstrates that the 90-10 model is the most effective form of immersion education, in terms of both academic and linguistic outcomes. Following this model for the early Elementary grades, at HoLa, 90% of instruction is delivered in Spanish in grades K-2, with one daily period of English Language Arts. Starting in 3rd grade, instruction gradually shifts to 50% of academic content delivered in Spanish and 50% delivered in English. Immersion classrooms are dynamic, creative spaces. Our teachers implement innovative strategies to facilitate comprehension and communication, integrate linguistic and academic content, and differentiate instruction. We believe bilingualism is a critical 21st Century skill that builds bridges and brings communities together, whether they are next door or across the globe.
