The most critical feature of a common-item nonequivalent groups equating design is that the average score difference between the new and old groups can be accurately decomposed into a group ability difference and a form difficulty difference. Two widely used observed-score linear equating methods, the Tucker and the Levine observed-score methods,…

This study investigates whether the functions linking number-correct scores to the College-Level Examination Program (CLEP) scaled scores remain invariant over gender groups, using test data on the 16 testlet-based forms of the CLEP College Algebra exam. To be consistent with the operational practice, linking of various test forms to a common…

The 2006-2007 school year was the eighth annual reporting period since disaggregating the performance of students with disabilities on state and district-wide assessments was required by the Individuals with Disabilities Education Act (IDEA). It is the fifth reporting period since the enactment of the No Child Left Behind Act (NCLB), and the…

When a state test and National Assessment of Educational Progress (NAEP) are both measuring the same construct, the achievement gaps between subgroups on both tests should be the same. However, if a teacher or school engages in "teaching to the test" then student performance may improve on one test but not on another. We hypothesized that…

The Toronto Board of Education Benchmarks are libraries of reference materials that demonstrate student achievement at various levels. Each library contains video benchmarks, print benchmarks, a staff handbook, and summary and introductory documents. This book is about the development and the history of the benchmark program. It has taken over 3…

To refocus its professional development plan, Chaska Middle School East (Minnesota) looked at where student achievement was lagging. Using the Killion back-mapping model, a student-focused, data-driven, multi-step process by which teachers gather and study student data to determine where professional growth, development, or training is most…

In this study, special education teachers identified students with learning disabilities who were working on math skills usually taught two grades below the grade in which the student was enrolled. Each student (n=33) took two levels of the MAT/7 math computation test, an on-grade test, and an out-of-level test intended for students two grades…
