NAEP Technical DocumentationWriting Assessment Subscale Composition for New and Previously Administered Blocks at Grade 8

Each writing assessment usually includes blocks of new items and blocks of items from previous assessments. However, in 2011, a new writing framework was introduced and all new items were created for the assessment. For these new items in the writing scale, the number of multiple-choice, dichotomously scored constructed-response, and polytomously scored constructed-response items are provided at grade 8. The item counts are available for each scale as defined in the final Item Response Theory (IRT) scales.

Scale composition for new blocks as defined after scaling, grade 8 writing national assessment, by item type and scale: 2011

Scale	Multiple-choice items		Dichotomously scored constructed-response items		Polytomously scored constructed-response items
	Scaled	Dropped	Scaled	Dropped	Polytomous uncollapsed	Dichotomous collapsed	Polytomous collapsed	Dropped
1 Single overall scale. NOTE: "Dropped" denotes items that were deleted from the final scaling. "Collapsed" denotes items that had categories that were combined and recoded for scaling. Some items were administered previously under different contexts.
