NAEP Technical DocumentationMathematics Assessment Subscale Composition for New and Previously Administered Blocks at Grade 8: 2003

Each mathematics assessment includes blocks of new items and blocks of items from previous assessments. For the new items and for the previously administered items in each mathematics scale, the number of multiple choice, dichotomously scored constructed-response and polytomously scored constructed-response items are provided for grade 8. The item counts are available for each scale as defined in the final Item Response Theory (IRT) scales.

Scale composition by item type for new blocks as defined after scaling, grade 8 mathematics combined national and state main assessment: 2003

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
Total	31	0	4	0	2	0	0	0
Number sense, properties and operations	8	0	0	0	1	0	0	0
Measurement	5	0	1	0	0	0	0	0
Geometry and spatial sense	4	0	2	0	0	0	0	0
Data analysis, statistics, and probability	5	0	0	0	1	0	0	0
Algebra and functions	9	0	1	0	0	0	0	0
NOTE: "Dropped" denotes items that were deleted from the final scaling. "Collapsed" denotes items that had categories that were combined and recoded for scaling.

NOTE: "Concurrent" denotes items that were scaled as common items across assessment years. "Split" denotes items that were scaled as different items in each assessment year. "Dropped" denotes items that were deleted from the final scaling. "Collapsed" denotes items that had categories that were combined and recoded for scaling.
