Abstract	Three strategies for linking two consecutive assessments are investigated and compared by analyzing reading data for the National Assessment of Educational Progress (NAEP) using the general diagnostic model. These strategies are compared in terms of marginal and joint expectations of skills, joint probabilities of skill patterns, and item parameter estimates. The results indicate that fixing item parameter values at their previously calibrated values is sufficient to establish a comparable scale for the subsequent year. (As Provided).
