As part of its mission, Educational Testing Service (ETS) has conducted education policy research focused on promoting equal opportunity for all individuals from early childhood through adulthood. This report provides a sampler of this extensive work in three areas chosen to represent major historical foci: (1) Analyzing, evaluating, and informing public policy in educational governance, including school finance; teacher policy; and federal, state, and local education policy; (2) Examining differential access to educational opportunity in three areas of longstanding interest to ETS: the gender gap, advanced placement programs, and graduate education; and (3) Reporting on the educational outcomes of the U.S. population and describing the contexts for these outcomes and for the gaps in outcomes that exist among segments of the population.
