Description: Diagnostic appraisals of examinee ability on multiple skills or multiple facets of understanding are often required in educational assessment, especially in formative assessment settings, and represent one of the most important lines of research in measurement today. The Arpeggio Suite is a statistical analysis package that runs in Windows, and is the first assessment package specifically designed for this cutting-edge type of analysis. Using the Fusion Model, a sophisticated and flexible IRT model developed for such analyses, Arpeggio classifies examinees as masters or nonmasters of the user-specified skills and provides information regarding the discrimination of items and the test as a whole with respect to those skills. Arpeggio is ideal for educational measurement research concerning skills diagnostics as well as for applied educational assessments where skills diagnostics are required to provide greater examinee feedback.
