Abstract

This paper provides a history of ETS’s role in developing assessment instruments and psychometric procedures for measuring change in large-scale national assessments funded by the Longitudinal Studies branch of the National Center for Education Statistics. It documents the innovations developed during more than 30 years of working with longitudinal studies based on national samples. In addition to describing these innovations, it provides their rationale and presents some empirical results in their support.
