Palacio, Marcela; Gaviria, Sandra; Brown, James Dean – PROFILE: Issues in Teachers' Professional Development, 2016
Frustrations with traditional testing led a group of teachers at the English for adults program at Universidad EAFIT (Colombia) to design tests aligned with the institutional teaching philosophy and classroom practices. This article reports on a study of an item-by-item evaluation of a series of English exams for validity and reliability in an…

Hendrickson, Amy; Patterson, Brian; Ewing, Maureen – College Board, 2010
The psychometric considerations and challenges associated with including constructed response items on tests are discussed along with how these issues affect the form assembly specifications for mixed-format exams. Reliability and validity, security and fairness, pretesting, content and skills coverage, test length and timing, weights, statistical…

Echternacht, Gary – Educational and Psychological Measurement, 1975
Estimates for the variances of empirically determined scoring weights are given. It is also shown that test item writers should write distractors that discriminate on the criterion variable when this type of scoring is used. (Author)

Gavin, Anne T.; Martin, Charles G. – 1976
A procedure for estimating the degree to which a subtest uniquely contributes to total test performance is presented and discussed. Uniqueness analysis may be appropriately applied to any composite measurement instrument such as a multipart test or a multitest battery to assess the unique contribution of each component to the total test. The…

Livingston, Samuel A. – 1984
Much previously published material for estimating the reliability of classification has been based on the assumption that a test consists of a known number of equally weighted items. The test score is the number of those items answered correctly. These methods cannot be used with classifications based on weighted composite scores, especially if…

Bayuk, Robert J. – 1973
An investigation was conducted to determine the effects of response-category weighting and item weighting on reliability and predictive validity. Response-category weighting refers to scoring in which, for each category (including omit and "not read"), a weight is assigned that is proportional to the mean criterion score of examinees selecting…

Reilly, Richard R.; Jackson, Rex – 1972
Evidence on how the psychometric properties of verbal and quantitative academic aptitude tests are affected when item options are weighted using rather simple conceptual procedures is presented. This is discussed in connection with the scoring methods used on the Graduate Record Examinations. (DG)

Donlon, Thomas F. – 1975
This study empirically determined the optimizing weight to be applied to the Wrongs Total Score in scoring rubrics of the general form = R - kW, where S is the Score, R the Rights Total, k the weight and W the Wrongs Total, if reliability is to be maximized. As is well known, the traditional formula score rests on a theoretical framework which is…

Garvin, Alfred D. – 1972
Various aspects of Confidence Weighting are examined. Variant of Confidence Weighting, its effect on test reliability, and the validity of Confidence Weighting are discussed. (DG)

Downey, Ronald G.
Previous research has studied the effects of different methods of item option weighting on the reliability and concurrent and predictive validity of achievement tests. Increases in reliability are generally found, but with mixed results for validity. Several methods of producing option weights, (i.e., Guttman internal and external weights and…

Hendrickson, Gerry F. – 1971
The purpose of this study was to determine whether option weighting improved the internal consistency and intercorrelation of the subtests. The differential option-weighting scheme employed in this study is based on one devised by Guttman. The tests were first scored with Guttman-type weights and then with conventional correction-for-guessing…

Rippey, Robert M. – 1971
Technical improvements, which may be made in the reliability and validity of tests through confidence scores, are discussed. However, studies indicate that subjects do not handle their confidence uniformly. (MS)

Swineford, Frances – 1972
Seventeen 1971 AERA presentations concerning new measurement procedures or new application of old procedures are summarized. Papers are grouped as follows: 1) statistics and measurements of interest to classroom teachers; 2) measures appropriate for use by a specialist; 3) research reports that increase knowledge of existing devices.
