Abstract
I describe how a policy aimed at increasing achievement among students labeled EL initially went awry—and how a researcher-district partnership persevered to rectify it. The policy, which called for 100% EL classrooms, produced unintended consequences. Critical discussion of empirical evidence and district-solicited input from multiple constituencies brought to light sociocultural, sociopolitical, and socioeconomic factors. This shift enabled policymakers to rectify the policy, allowing integration of ELs with non-EL peers.
