Defining coorientational accuracy as how closely one person estimates another's orientation to something cooriented, this paper examines the reasons why the concept has been favored as a criterion for communicating and how it has been measured. It notes problems in measuring accuracy with reference to various ways the orientation situation has…

Ten different weighting schemes were applied to the responses to a self-report deliquency measure and the resulting scores were evaluated in a multitrait-multimethod analysis. Four subscores and a total score were derived from the 35-item questionnaire which was administered orally on four occasions during an 18-week deliquency prevention project.…

The final report describes a project to facilitate the efficiency with which legally blind persons use their remaining vision. The project developed a diagnostic assessment procedure, a design for instruction which includes 150 sequenced lessons, and a sourcebook on low vision. The reliability and validity of the diagnostic assessment procedure…

Certain testing procedures will overcome some of the problems associated with the use of essay tests. Essay tests may not validly indicate achievement because the questions included in the test may not fairly represent instructional content. Reliability may be a problem because of variations in examinee response in different situations, in test…

Four criterion-referenced reliability coefficicents were compared to the Kuder-Richardson estimates and to each other. The Kuder-Richardson formulas 20 and 21, the Livingston, the Subkoviak and two Huynh coefficients were computed for a random sample of 33 criterion-referenced tests. The Subkoviak coefficient yielded the highest mean value;…

A general framework for making mastery/nonmastery decisions based on multivariate test data is described in this study. Over all, mastery is granted (or denied) if the posterior expected loss associated with such action is smaller than the one incurred by the denial (or grant) of mastery. An explicit form for the cutting contour which separates…

Ordinal response modes for multiple choice tests are those under which the examinee marks one or more choices in an effort to identify the correct choice, or include it in a proper subset of the choices. Two ordinal response modes: answer-until-correct, and Coomb's elimination of choices which examinees identify as wrong, were analyzed for scoring…

The Vocational Performance Sample (VPS), a vocational assessment instrument for the severely retarded, integrates norm referenced technology with current innovations in domain referenced tests and learning potential assessment. The domains are based on a systematic sampling of types of training procedures and types of discriminations and/or…

Fair, valid, and reliable measurement of dependent variables is a concern in personnel evaluation studies. Performance tests, that is, job or work sample tests, situational tests, and job learning or trainability tests, are being used with increasing frequency as measurement techniques capable of meeting these needs. The three categories of…

Three areas of concern related to test bias and validity should be considered during the revision of the Standards for Educational and Psychological Tests. The first area concerns the sources and consequences of test bias. Five sources of bias have been identified: numerical bias, role bias, status bias, stereotypic bias, and familiarity bias. The…

In 1973, kindergarten children in a rural village in Texas were tested with the McCarthy Scales of Children's Abilities. For the next 2.5 years, children from successive grades in the same school were given the same test. During the entire period over 200 children had been tested, but of the original 53 pupils only 20 took the test all three times…

The evaluation model for mastery testing as proposed by Emrick (1971) represents an empirical approach to determining the most appropriate mastery criterion score that should be established in those testing situations which entail decision making relative to the continued progression or possible recycling of students in a given learning sequence.…

The purpose of this study was to administer the revised "Inventory of Teacher Knowledge of Reading" by Artley and Hardin to a representative population of teachers, and to secure information concerning the factorial validity and reliability of the instrument. The subjects included 552 inservice elementary education teachers, elementary…
