Year - to - year changes in average writing performance for a sample of 188 schools were estimated with a group - level version of the geenralized partial credit IRT model. School - level IRT - based equating adjustments were required to provide a stable scale over the 2 years and to estimate year - to - year changes in avergae performance for the sample of schools. The results illustrated that technical equating adjustments can be important even when there have been rigorous efforts to write new prompts comparable in difficulty to the old and to train new rating teams to implement earlier standards of writing sample grading.
