Impact of Changing Difficulty on Inferences from the National Assessment of Educational Progress.
Cohen, Jon; Snow, Stephanie
Journal of Educational Measurement, v39 n2 p91-114 Sum 2002
Studied the impact of changes in item difficulty on National Assessment of Educational Progress (NAEP) estimates over time through a Monte Carlo study that simulated the responses of 1990 NAEP mathematics respondents to 1990 and 1996 NAEP mathematics items. Results support the idea that these changes have not affected the NAEP trend line. Discusses limitations of this study. (SLD)
