The equating process links scores from different editions of the same test. For testing programs that build nearly parallel forms to the same explicit content and statistical specifications and administer forms under the same conditions, the linkings between the forms are expected to be equatings. Score equity assessment (SEA) provides a useful…

Research studies have shown that a smaller percentage of students with learning disabilities participate in state assessments than do their peers without learning disabilities. Furthermore, there is almost always a performance gap between these groups of students on these assessments. It is important to evaluate whether a performance gap on a…

This report evaluates the construct coverage of the e-rater[R[ scoring engine. The matter of construct coverage depends on whether one defines writing skill, in terms of process or product. Originally, the e-rater engine consisted of a large set of components with a proven ability to predict human holistic scores. By organizing these capabilities…
