The specialized language immersion program allows English-proficient students to become bilingual and bi-literate in Spanish. Students attending the immersion program receive all classroom instruction in Spanish beginning in kindergarten. Through exposure to and practice with the language, students gain understanding and develop language proficiency. English language arts are introduced beginning in 3rd - 5th grade. Parents of this program agree to read to their child in English for a minimum of 20 minutes a day. Students whose first language is not English must demonstrate proficiency in English prior to enrollment at Sonia Sotomayor.

The application process occurs the year before students enter kindergarten.

The goal of Two-Way Spanish Immersion is full bilingualism and biliteracy in both Spanish and English for English and Spanish-speaking children. Two-Way Immersion is a distinctive form of immersion education in which balanced numbers of native English and Spanish speakers learn together to read, write, speak and listen in both languages. All academic content is delivered equally across the two languages to students throughout the school day. Students work at the exact same academic level as traditional classroom students. They learn the same content to the same high expectations. In middle school, Two-Way Immersion students can continue with bilingual instruction, combined with students from the Sonia Sotomayor Elementary Spanish Immersion students.
