Laboratory courses serve as important gateways to science, technology, engineering, and mathematics education. One of the challenges in assessing laboratory learning is to conduct meaningful and standardized practical exams, especially for large multisection laboratory courses. Laboratory practical exams in life sciences courses are frequently…

This study investigated the application of multidimensional item response theory (IRT) models to validate test structure and dimensionality. Multiple content areas or domains within a single subject often exist in large-scale achievement tests. Such areas or domains may cause multidimensionality or local item dependence, which both violate the…

Data from the grade 8 and grade 10 science tests of the National Education Longitudinal Study of 1988 (NELS:88) were used to demonstrate that achievement tests are multidimensional and that using psychologically meaningful subscores in national surveys can enhance test validity and usefulness.

Connecticut is developing a new grade 10 statewide testing program known as the Connecticut Academic Performance Test (CAPT). The CAPT reflects the changing nature of standardized assessment by using a variety of assessment formats including performance tasks, open-ended questions, and multiple-choice tests. This paper describes the research that…

The role of expert judges in establishing the content validity of the National Teacher Examinations (NTE) was examined in a detailed study. The NTE are used in 22 states for screening applicants to teacher education programs and/or for screening candidates for initial teacher certification. Such extensive use of the NTE has stimulated 35 recent…
