The mission of the Regional Educational Laboratories (RELs) is to help states, districts, and territories use data and research to improve student outcomes. RELs build capacity to do three things: (1) Use data to identify target areas for improvement; (2) Select the best approaches for improvement, drawing on credible and up-to-date research; and (3) Track the outcomes and evaluate the effects of those choices. The RELs work with their regions through Research Alliances. The Research Alliances for the Pacific RELs are presented in this document.
