Scoring procedures for the constructed-response (CR) items in large-scale mixed-format educational assessments often involve checks for rater agreement or rater reliability. Although these analyses are important, researchers have documented rater effects that persist despite rater training and that are not always detected in rater agreement and…

Some statewide testing programs allow students to receive corrective feedback and revise their answers during testing. Despite its pedagogical benefits, the effects of providing revision opportunities remain unknown in the context of alternate assessments. Therefore, this study examined student data from a large-scale alternate assessment that…

We investigated how item formats influence test takers' response tendencies under uncertainty. Adult participants solved content-equivalent math items in three formats: multiple-selection multiple-choice, grid with forced-choice (true-false) options, and grid with non-forced-choice options. Participants showed a greater tendency to commit (rather…

While previous research has identified numerous factors that contribute to item difficulty, studies involving large-scale reading tests have provided mixed results. This study examined five selected-response item types used to measure reading comprehension in the Pearson Test of English Academic: a) multiple-choice (choose one answer), b)…

Assessment items are commonly field tested prior to operational use to observe statistical item properties such as difficulty. Item parameter estimates from field testing may be used to assign scores via pre-equating or computer adaptive designs. This study examined differences between item difficulty estimates based on field test and operational…

Tablets can be used to facilitate systematic testing of academic skills. Yet, when using validated paper tests on tablet, comparability between the mediums must be established. Comparability between a tablet and a paper version of a basic math skills test (HRT: Heidelberger Rechen Test 1-4) was investigated. Five samples with second and third…

Item stem formats can alter the cognitive complexity as well as the type of abilities required for solving mathematics items. Consequently, it is possible that item stem formats can affect the dimensional structure of mathematics assessments. This empirical study investigated the relationship between item stem format and the dimensionality of…
