Since the No Child Left Behind Act (No Child Left Behind [NCLB], 2001) was enacted, the Bookmark method has been used in many state standard setting studies (Karantonis and Sireci; Zieky, Perie, and Livingston). The purpose of the current study is to evaluate the criticism that when panelists are presented with data during the Bookmark standard…

Although much research has been conducted on the psychometric properties of cognitive diagnostic models, they are only recently being used in operational settings to provide results to examinees and other stakeholders. Using this newer class of models in practice comes with a fresh challenge for diagnostic assessment developers: effectively…

Recent research has proposed a criterion to evaluate the reportability of subscores. This criterion is a value-added ratio ("VAR"), where values greater than 1 suggest that the true subscore is better approximated by the observed subscore than by the total score. This research extends the existing literature by quantifying statistical…

Drawing valid inferences from modern measurement models is contingent upon a good fit of the data to the model. Violations of model-data fit have numerous consequences, limiting the usefulness and applicability of the model. As Bayesian estimation is becoming more common, understanding the Bayesian approaches for evaluating model-data fit models…

The framework and procedures of generalizability theory are introduced and illustrated in this instructional module that uses a hypothetical scenario involving writing proficiency. Generalizability analyses are useful for understanding the relative importance of various sources of error and for designing efficient measurement procedures. (SLD)

How portfolio-based conclusions about student learning might be used to communicate with audiences outside the classroom is explored. Procedures and criteria for investigating validity in portfolio use are discussed. Ten portfolios from an eighth grade language arts class are used as an example. (SLD)
