Where is the Value in Value-Added Modeling?

This paper first provides an overview of value-added modeling (VAM), including definitions and descriptions of three general types of value-added models. The paper then summarizes the rationales for and against incorporating VAM into an accountability framework. Finally, we provide a recommendation that VAM estimates be used in conjunction with other measures to form a composite.

Putting Ducks in a Row: Methods for Empirical Alignment of Performance Scoring

Using historical state data, this report evaluates nine different methods of aligning performance standards and discusses the effects of selecting different methods as well as the potential implications for interpretations of student progress and school success.

AutoCorreleation in the COFM. The effects of Autocorrelation on the Curve-of-factors Growth Model

This simulation study examined the performance of the curve-of-factors model (COFM) when autocorrelation and grwth processes were present in the first-level factor sturcture.  In addition to the standard curve-of-factors growth model, two new models were examined: one COFM that included a first-order autoagressive atuocorrelation parameter, and a second model that included first-order autoregressive and voving average autocorrelation parameters.
