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.
