Assessing students' emerging literacy skills is crucial for identifying areas where a child may be falling behind and can lead directly to an increased chance of reading success. The Waterford Assessment of Core Skills (WACS), a computerized adaptive test of early literacy for students in prekindergarten through 2nd grade, addresses this need.…

The FAIR-FS consists of computer-adaptive reading comprehension and oral language screening tasks that provide measures to track growth over time, as well as a Probability of Literacy Success (PLS) linked to grade-level performance (i.e., the 40th percentile) on the reading comprehension subtest of the Stanford Achievement Test (SAT-10) in the…

Recently, educational researchers and practitioners have turned to value-added models to evaluate teacher performance. Although value-added estimates depend on the assessment used to measure student achievement, the importance of outcome selection has received scant attention in the literature. Using data from a large, urban school district, I…

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…

The extent to which national performance on an achievement test battery changed over a 4-year period was studied, and the comparative performance of students in school districts taking the test series for the first time was compared with that of students in districts that had used the battery at least once in one or more grades. The seventh…

Both on-level and out-of-level tests were administered to third and fifth grade children in order to compare the scaled scores of different level tests of the same testing program and to discover whether the relationship between levels might be distorted by ceiling or floor effects. Only reading tests were used in this study. The Stanford…

The final report describes the accomplishments of an 18-month study designed to adapt and standardize the 7th Edition of the Stanford Achievement Test with a national, randomly drawn sample of hearing-impaired students. The following objectives were accomplished: (1) test material and special procedures were developed and disseminated; (2) the…

Results of three studies based on Stanford Achievement Test data collected during the National Achievement Testing Program for Hearing Impaired Students in Spring, 1971 are reported. Compared in the first study are performance patterns of hearing impaired students on the Intermediate I and Advanced batteries with patterns of hearing…

This manual summarizes technical information regarding the 1982 Stanford Achievement Test, Seventh Edition when administered to hearing-impaired students. In Section 1, the procedures used to select the norming sample (7,557 hearing-impaired students) are described, and the demographic characteristics of the resulting sample are compared to those…

The authors argue that personnel who select standardized achievement tests have been led to believe that the major achievement test batteries differ very little in terms of the topics they test; but that the content covered by these major tests is different, and that such differences have consequences for instructional content. To test this…
