Beaverton School District partnered with Education Northwest to identify which of the English language development (ELD) program models they use are most effective at improving English learner (EL) outcomes. The major results of the study indicate that there was no advantage to providing more than 50 minutes of ELD per day. In terms of instructional model, the dual language and co-teaching models had better long term outcomes for grade-to-grade English proficiency than pull-out programs.
