Biography

Louis T. Mariano is a statistician in the Washington D.C. office and a professor at the Pardee RAND Graduate School. His education research has focused on evaluations of the implementation and efficacy of school reform efforts; furthering the development of value-added models for estimating teacher effects; the expansion of item response theory models, with emphasis on the reduction of measurement error; and the application of quasi-experimental designs. He recently concluded co-directing a four-year longitudinal study of New York City's student promotion policy and is currently leading a project aimed at improving the statistical estimates of program treatment effects when program participation may be triggered by multiple performance thresholds.
