Analysis of Item Response Patterns: Consistency Indices and Their Application to Criterion-Referenced Tests.
Harnisch, Delwyn L.
The major emphasis of this paper is in the examination of test item response patterns. Tatsuoka and Tatsuoka (1980) have developed two indices of response consistency: the norm-conformity index (NCI) and the individual consistency index (ICI). The NCI provides a measure of the degree of consistency between the response pattern of an individual and the difficulty ordering of the items for a norm group. The ICI provides a measure of the degree to which an individual's response pattern remains internally consistent within a topic or item type over time. The NCI and ICI were computed for 357, 396, and 643 third, sixth, and seventh/eighth grade students, respectively, on the Basic Arithmetic Skills Evaluation (BASE), a criterion-referenced test. There is a positive correlation between the consistency indices and the total test score across the three grade levels. The indices correlated very highly with each other. (Author/BW)
