NAEP Technical DocumentationCivics Assessment Subscale Composition for New and Previously Administered Blocks at Grade 12

The NAEP civics assessment is based on a framework that specifies a single scale. Because this type of table is supplied for all subject areas on this website, the table format has been maintained for civics to clarify which treatments are possible and which are not. For the new items and for the items administered in a previous civics assessment, the number of polytomously scored constructed-response items is provided. This item count is defined in the final Item Response Theory (IRT) scales.

Scale composition for new blocks as defined after scaling, grade 12 civics national main assessment, by item type: 2006

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	30	0	0	0	8	0	1	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.

Scale composition for previously administered blocks as defined after scaling, grade 12 civics assessment, by item type: 2006

Scale	Multiple-choice items			Dichotomously scored constructed-response items			Polytomously scored constructed-response items
	Concurrent	Split	Dropped	Concurrent	Split	Dropped	Concurrent polytomous uncollapsed	Concurrent dichotomous collapsed	Concurrent polytomous collapsed	Split	Dropped
Total	92	3	1	0	0	0	22	3	0	2	0
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.
