| "Concurrent" and “uncollapsed” denote items that were scaled as the same items across assessment years. "Split" denotes items that were scaled as different items in each assessment year. Items may be split if they display cross-year drift and need to be treated as separate items. "Dropped" denotes items that were deleted from the final scaling. "Collapsed" denotes items that had categories that were combined and recoded for scaling. Polytomous items may be collapsed if they show IRT misfit and adjacent categories need to be combined to achieve better IRT model fit. For multiple-choice and dichotomously scored constructed-response items, the total number of items is the sum of the three categories: concurrent, split, and dropped. The number of concurrent polytomously scored constructed-response items equals the total number in the first three categories under "Polytomously sore constructed-response items" minus any polytomously scored items that have been split then collapsed. | |||||||||||
