The challenge of "educational" assessments--assessments that advance the purposes of learning and instruction--is to provide useful information regarding students' progress towards the goals of instruction in ways that are reliable and not idiosyncratic. In this commentary, the author indicates that the challenges are actually more…

States are increasingly interested in including measures of student achievement growth, or "value- added," in evaluating teachers. Annual state assessments, however, which are the typical measure of student growth, usually cover only reading and math teachers and only in grades 4-8. These state assessments thus cannot …

States and school districts are exploring alternatives to state tests for measuring teachers' contributions to student learning. One approach applies statistical value-added methods to alternative student assessments such as commercially available tests and end-of course tests. The evidence suggests that these methods can reliably distinguish…

An item analysis of the Stanford Achievement Test performance of about 12,000 students in schools and classes for the hearing impaired is presented. Tables show the percentage of correct answers to each question, as well as a summary of the responses for each sub-test and major categories within some sub-tests. Because the test was developed for…

The purpose of this study was to take an initial step toward developing sound and versatile predictive instruments (i.e., benchmark measures) in reading, writing, and math that can be used to assess high-school students' academic performance in a manner that will not only predict scores on high-stakes tests but will also be amenable to repeat…
