Improving retention and graduation rates for English language learner (ELL) students is a concern throughout the Northwest and particularly for Washington's South Seattle and South King County school districts that participate in the Road Map for Education Results initiative. In the seven Road Map districts, 22 percent of students fail to graduate on time. The goal of Road Map is to double the number of students who are on track to graduate from college or earn a career credential by 2020. To monitor progress toward this goal, Road Map districts currently use two early warning indicators that flag whether a student is at risk for high school dropout. This study seeks to determine the degree to which these indicators accurately predict dropout for the districts' many ELL students, as compared to the general student population. The results could potentially affect support given to thousands of ELL students in the Road Map districts.
