Northwest Evaluation Association™ (NWEA™) is committed to providing partners with useful tools to help make inferences from Measures of Academic Progress® (MAP®) interim assessment scores. One important tool is the concordance table between MAP and state summative assessments. Concordance tables have been used for decades to relate scores on…

Concordance tables have been used for decades to relate scores on different tests measuring similar but distinct constructs. These tables, typically derived from statistical linking procedures, provide a direct link between scores on different tests and serve various purposes. Aside from describing how a score on one test relates to performance on…

Student responses to the West Virginia Educational Standards Test (WESTEST) 2 Online Writing Assessment are scored by a computer-scoring engine. The scoring method is not widely understood among educators, and there exists a misperception that it is not comparable to hand scoring. To address these issues, the West Virginia Department of Education…

Purpose of this study was to test a short version of the Stanford-Binet, Form L-M using a group covering a wide age and ability level in an attempt to reduce the time factor involved in administration of some of the S-B tests, without sacrificing the reported accuracy. (Author/CB)

The High School Longitudinal Study of 2009 (HSLS:09) is the fifth in a series of National Center for Education Statistics (NCES) secondary longitudinal studies. The core research questions for HSLS:09 explore secondary to postsecondary transition plans and the evolution of those plans; the paths into and out of science, technology, engineering,…

This study investigated (a) interscorer reliability of the Bender-Gestalt Test by using more than one person to score the same test protocols; and (b) rate-rerate reliability of the Bender-Gestalt Test after a half-year interval. (Author)

The separation level of grades on a multiple-choice examination as a quantitative probabilistic criterion for correct classification of students by the examination was introduced by Krutchoff. (Author)

Although a great deal of attention has been devoted over a period of years to the estimation of reliability from item statistics, there are still gaps in the mathematical derivation of the Kuder-Richardson results. The main purpose of this paper is to fill some of these gaps, using language consistent with modern probability theory. (Author)

In this study a Q sort was developed to measure pupil self-image of science achievement in high school. The Q sort was described so that similar tests could be constructed to measure affective behavior for most classroom environments. (Editor/RK)

The present paper emphasizes the importance of making interpretations regarding differences among an individual's scores on a test battery based on this same concern for the appropriateness of the reference group. (Author)

Readability formulas are designed to provide quantitative estimates of the relative difficulty of pieces of writing. This study explored the extent to which an increase in the accuracy of a specific readability formula could be obtained by norming it for a restricted set of reading materials and subjects. (Editor)

Derives formulas for the validity of predictor-criterion tests that hold for all test scores constructed according to the expected-value concept of true score. These more general formulas disclose some paradoxical properties of test validity under conditions where errors are correlated and have some implications for practical testing situations…

This study researched the Plenk scoring system more thoroughly to see whether it could be used with older children and whether it could differentiate normal from emotionally disturbed Ss. (Author)

Schizophrenic and normal subjects' responses to the Stanford-Binet Vocabulary items, the Wechsler Adult Intelligence Scale (WAIS) Vocabulary items, and the WAIS Similarities items were scored by two methods, one relatively strict and the other relatively lenient. (Editor)
