The goal of the current study was to introduce a new stopping rule for computerized adaptive testing (CAT). The predicted standard error reduction (PSER) stopping rule uses the predictive posterior variance to determine the reduction in standard error that would result from the administration of additional items. The performance of the PSER was…

We study the properties of two specification tests that have been applied to a variety of estimators in the context of value-added measures (VAMs) of teacher and school quality: the Hausman test for choosing between random and fixed effects and a test for feedback (sometimes called a "falsification test"). We discuss theoretical…

It was concluded from the study that for predicting General Educational Development Test scores, the scores from the paragraph meaning and the individual subject matter areas of the SATB should be noted. (Author)

A discussion of an efficient assignment plan for the domain-referenced testing program to govern how examinees encounter the items. (Author)

A three-year study yielded data on the characteristics and progress of 44 preschool children with developmental delays of uncertain etiology. Findings support the use of traditional developmental tests for assessing developmental status. Analyses across time suggest that three assessments are needed before confident prediction is possible about…

A tailored testing model employing the beta distribution, whose mean equals the difficulty of an item and whose variance is approximately equal to the sampling variance of the item difficulty, and employing conditional item difficulties, is proposed. (Author)

This study explored the relationship between classification achievements and mathematics scores. A series of 16 items which included many of the traditional tasks used in Piagetian examinations of intellectual function, were used in group presentations. Ten of these tasks required concrete operations including class inclusion, additive…

This newsletter summarizes the work of a committee, set up by the Ministry of Education, which sought to define the objectives and the methods of student evaluation and to draw up a proposal for reforming and standardizing student evaluation in the comprehensive and the secondary school. Deficiencies of current methods of student evaluation are…

This final report summarizes past research and suggests new approaches to the problem of estimating long-term individual constants using path analysis. The general objective of the research was to detect and measure the likelihood that one variable, x, measured at time, t, has a causal influence on another variable, y, measured at a subsequent…

To evaluate the usefulness of standardized achievement tests in assessing pre-university academic achievement and aptitude, the Council of Ontario Universities administered tests to incoming freshmen at four Ontario universities, and also examined their high school and subsequent university performance. The tests were designed to measure…

An elementary survey of item characteristic curve theory, centered around the problems of individualized (tailored) testing, is presented. Following the introduction, discussions are provided of the following: Test Theory for Itemized Tests; The Guttman Scale; Item Characteristic Curve Theory; An Alternative Model; Specialization, Application, and…

The research project's objectives were: survey of the field, development of new approaches and techniques, investigation of factors in the employment of the trainable mentally retarded (TMR), development of objective measurement of work adjustment behaviors, selective application of new methods, and development of a model vocational evaluation…

To evaluate six perceptual-motor attributes of trainable and educable mentally retarded children, a battery of tests was constructed which included body perception, gross agility, balance, locomotor ability, throwing, and tracking; 83 retarded subjects provided reliability data, and their scores, with those of 120 additional subjects, provided…

This paper is a review of opinion and research concerning the objectivity and relevance of grades and grade averages as measures and as predictors of success. As measures they are ambiguous, reflecting differences in sex, basic temperament, instructors, departments, institutions, as much as levels of competence. And as a predictor of…
