Over the past few decades, there has been increasingly more research focused on instructional programs and practices for educating and preparing students for a linguistically-diverse global economy. Numerous research studies have shown that dual language/two-way immersion (DL) programs are effective at helping students become bilingual and fluent in English and another language.

Despite the benefits that have been noted based on students’ participation in DL programs, the majority of programs operate at the elementary level. This report highlights articles regarding DL (two-way immersion) programs operating within secondary schools. This research summary can serve as a reference tool that supports state education agency decision-making regarding developing, implementing, and assessing DL programs at the secondary level.
