Elementary Spanish.jpg


All children at Castle Island socialize, learn academics, and develop as members of their classroom community - in both English and Spanish!

Parents choose Castle Island for their children because they value language learning. Children enroll with a variety of backgrounds: some with language dominance in English, and some language dominance in Spanish. ​​

Our Bilingual Model
  • English and Spanish are spoken and taught simultaneously throughout the day and across the curriculum, including most special enrichment classes.


  • Our model is one language-one teacher. Each classroom is guided by two teachers. One presents individualized lessons in English and the other in Spanish.


  • Each child's lessons are are presented one-on-one with hands-on materials by either a Spanish-speaking or English-speaking teacher. This way, the child can access concrete understanding in acquiring language as well as learning academics.
