The Research Shows:

“By fifth grade, most students are rated as fluent in the second language.”

“Findings present evidence that higher levels of bilingual proficiency are associated with higher levels of academic achievement in both English and Spanish.”

“Evaluation results demonstrate that two-way immersion students meet and exceed the goals of the program: bilingual proficiency–fluency in their first and second language; biliteracy–scores at or above grade level in reading achievement in both languages; and performance at or above grade level in mathematics, social studies, and science.”
