Andrew Ho is a psychometrician interested in educational accountability metrics: an intersection between educational statistics and educational policies. He has studied the consequences of "proficiency"-based accountability metrics, the validation of high stakes test score trends with low stakes comparisons, and the potential for alternative accountability structures—like "growth models" and "index systems"—to improve school- and classroom-level incentives.
His current projects include articulating meaningful contrasts between state growth model approaches and developing new gap trend and growth metrics for cross-test comparison and validation. He has his Ph.D. in Educational Psychology and his M.S. in Statistics from Stanford University. Dr. Ho has been a postdoctoral fellow at the National Academy of Education and Spencer Foundation and a recipient of the Jason Millman Promising Measurement Scholar Award from the National Council on Measurement in Education.
