Subscale Composition by Item Type for New and Trend Blocks in the Mathematics Assessment at Grade 8: 2000
Each assessment includes blocks of new items and blocks of items from previous assessments. For the new items and for the trend items in each subject area scale, the number of multiple-choice, dichotomously scored constructed-response and polytomously scored constructed-response items are provided for each grade level. The item counts are available for each scale as defined in the final Item Response Theory (IRT) scales. They are provided for samples for which accommodations were permitted and for samples for which accommodations were not permitted.
