NAEP Technical Documentation Block and Scale Composition, Grade 4 Mathematics Combined National and State Assessment: 2017

Block composition before scaling, grade 4 mathematics combined national and state assessment, by item type and block: 2017

Block	Total number of items	Number of multiple-choice items	Number of constructed-response items
			2-category	3-category	4-category	5-category
Total	177	104	22	45	3	3
M1	14	2	2	9	0	1
M2	16	4	4	7	0	1
M3	15	3	4	6	2	0
M4	20	16	1	3	0	0

M8	15	4	4	6	0	1
M9	20	15	2	3	0	0
M10	20	16	3	1	0	0
NOTE: For a small number of constructed-response items, adjacent categories were combined. SOURCE: U.S. Department of Education, Institute of Education Sciences, National Center for Education Statistics, National Assessment of Educational Progress (NAEP), 2017 Mathematics Assessment.

Scale composition for blocks as defined after scaling, grade 4 mathematics combined national and state assessment, by item type and subscale: 2017

Subscale	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	102	2	22	0	38	9	1	3
Number properties and operations	38	0	10	0	13	5	0	0
Measurement	18	0	4	0	5	2	1	0
Geometry	17	0	3	0	7	1	0	2
Data analysis, statistics, and probability	15	1	2	0	5	0	0	1
Algebra	14	1	3	0	8	1	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. Some items were administered previously under different contexts. All blocks in the 2017 grade 4 mathematics assessment were new blocks.
