c parameters are not estimated for the two-parameter logistic model or generalized partial credit models, and
d parameters are not estimated for two-parameter or three-parameter logistic models. NOTE: For item j, aj represents the discriminatory power of the item, bj represents a location parameter related to item difficulty, cj represents the guessing parameter, and dji represents the category threshold parameter for category i. The c parameter value is assumed to be exactly zero and is not estimated for items scaled with the two-parameter logistic model. For item j,dji may not sum to zero because of rounding. In 2016, grades 4 and 12 were not assessed.
