Part of the Mountain View Whisman School District, Mariano Castro Elementary school has 510 students enrolled from pre-school through fifth grade. Its unique language programs draw families from both inside and outside of Mountain View. The school tailors programs that are aimed for students who want to learn to read, write and speak fluently in English and Spanish.
The Spanish-English Dual Immersion Program aims to make children fluent in both languages by teaching native English-speaking and native Spanish-speaking students together, emphasizing Spanish in the earlier grades (K-2) and English in the latter (3-5). The English neighborhood program has a rigorous curriculum and all core classes are taught in English.
