Five statistical indices are developed and described which may be used for determining (1) when linear equating of two approximately parallel tests is adequate, and (2) whan a more complex method such as equipercentile equating must be used. The indices were based on: (1) similarity of cumulative score distributions; (2) shape of the raw-score to…

Experiences with competency testing at the elementary level in the area of English language are presented, as well as suggestions for improving the quality of competency tests. In order to modify curricula and requirements to meet the demands of assessment and to ensure sufficient student instruction, the following suggestions are made: (1)…

As an alternative for or adjunct to paper-and-pencil tests for predicting personnel performance, the United States Air Force studied the use of peer ratings as an evaluative tool. Purpose of this study was to evaluate the psychometric characteristics of peer ratings among Air Force basic trainees. Peer ratings were obtained from more than 27,000…

Number right and elimination scores were analyzed on a 48-item college level mathematics test that was assembled from pretest data in three forms by varying the item orderings: easy-hard, uniform, or random. Half of the forms contained information explaining the item arrangement and suggesting strategies for taking the test. Several anxiety…

The norm-referenced score scale used by the National Foundation for Educational Research (NFER) is described. The usefulness of standardized scores is explained by a simple numerical example, and the formulas and computations are shown for calculating a mean, a standard deviation, and a deviation or z score. The need for a representative sample is…

The one parameter latent trait theory of Georg Rasch has two assumptions: that student abilities can be measured on an equal interval scale, and that the success of a student with a given item is a function of student achievement and item difficulty. The grade four Michigan Educational Assessment Program reading test was designed to measure…

In this paper, an attempt has been made to synthesize some of the current thinking in the area of criterion-referenced testing as well as to provide the beginning of an integration of theory and method for such testing. Since criterion-referenced testing is viewed from a decision-theoretic point of view, approaches to reliability and validity…

A potentially valuable measure of overconfidence on probabilistic multiple-choice tests was evaluated. The measure of overconfidence was based on probabilistic responses to nonsense items embedded in a vocabulary test. The test was administered under both confidence response and conventional choice response directions to 208 undergraduate…

An examinee is required to express his confidence in the correctness of each choice of a multiple-choice item in a probabilistic test. For the responses to be valid indicators the confidence expressed in each choice should be determined by an examinees' knowledge. This study assessed the relationship of the certainty of examinees' responses to…

The need for a new projective instrument for use with low-income, disadvantaged populations is postulated in this study, and the development of such an instrument, the Value Orientation Test (VOT), is undertaken. With a theoretical foundation drawn from the "culture of poverty" school of thought, the test is related to the implicit…

This report describes the stratified adaptive (stradaptive) test as a strategy for tailoring an ability test to individual differences in testee ability; administration of the test is controlled by a time-shared computer system. The rationale of this method is described as it derives from Binet's strategy of ability test administration and…

A set of Tests of Scientific Thinking were developed for possible use as criterion measures in research on creativity. Scores on the tests describe both quality and quantity of ideas produced in formulating hypotheses, evaluating proposals, solving methodological problems, and devising methods for measuring constructs.

To forecast four-year, two-year, and single-course grades in college, a California Psychological Inventory equation was developed. Cross-validational coefficients for scores on the equation were .38 for 326 males and .36 for 570 females. (Author/GDC)

The indices of item difficulty and discrimination, the coefficients of effective length, and the average item information for both single- and multiple-answer items using six different scoring formulas were computed and compared. These formulas vary in terms of the assignment of partial credit and the correction for guessing. (Author/BW)

Describes procedure for combining Stanford Achievement Test items with local supplementary items to measure individual and aggregate student performance in mathematics. Two reports are generated from the test results: a diagnostic report of student mastery of each objective and an overall score. (TE)
