The purpose of this article was to model United States Medical Licensing Examination (USMLE) Step 2 passing rates using the Cox Proportional Hazards Model, best known for its application in analyzing clinical trial data. The number of months it took to pass the computer-based Step 2 examination was treated as the dependent variable in the model.…

How computers are used to analyze item data is reviewed, and the information that existing item-analysis programs provide is described. Summaries of studies comparing the performance of some of these packages reveal some of their current limitations. Emphasis is on the usefulness to educational practice of these packages. (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)
