Performance of students in low-stakes testing situations has been a concern and focus of recent research. However, researchers who have examined the effect of stakes on performance have not been able to compare low-stakes performance to truly high-stakes performance of the same students. Results of such a comparison are reported in this article.…

Research on examinees' response changes on multiple-choice tests over the past 80 years has yielded some consistent findings, including that most examinees make score gains by changing answers. This study expands the research on response changes by focusing on a high-stakes admissions test--the Verbal Reasoning and Quantitative Reasoning measures…

Both testlet design and hierarchical latent traits are fairly common in educational and psychological measurements. This study aimed to develop a new class of higher order testlet response models that consider both local item dependence within testlets and a hierarchy of latent traits. Due to high dimensionality, the authors adopted the Bayesian…

Data from 181 college students were used to assess whether math reasoning item response times in computerized testing can provide valid and reliable measures of a speed dimension. The alternate forms reliability of the speed dimension was .85. A two-dimensional structural equation model suggests that the speed dimension is related to the accuracy…

Extensive research has examined the effectiveness of admissions tests for use in higher education. What has gone unexamined is the extent to which tests are similarly effective for predicting performance at both the master's and doctoral levels. This study empirically synthesizes previous studies to investigate whether or not the Graduate Record…
