Test assembly is the process of selecting items from an item pool to form one or more new test forms. Often new test forms are constructed to be parallel with an existing (or an ideal) test. Within the context of item response theory, the test information function (TIF) or the test characteristic curve (TCC) are commonly used as statistical…

Mixed-format tests containing both multiple-choice (MC) items and constructed-response (CR) items are now widely used in many testing programs. Mixed-format tests often are considered to be superior to tests containing only MC items although the use of multiple item formats leads to measurement challenges in the context of equating conducted under…

The purpose of this dissertation was to investigate how different Item Response Theory (IRT)-based calibration methods affect student achievement growth pattern recovery. Ninety-six vertical scales (4 x 2 x 2 x 2 x 3) were constructed using different combinations of IRT calibration methods (separate, pair-wise concurrent, semi-concurrent, and…

The author investigated the impact of assessment methods on student performance on accounting tests. Specifically, the author used analysis of variance to determine whether the use of computer-based tests instead of paper-based tests affects students' traditional test scores in accounting examinations. The author included 2 independent variables,…
