This paper follows a line of logical argumentation to claim that what Samuel Messick conceptualized about construct validation has probably been misunderstood by some educational policy makers, practicing educators, and classroom teachers. It argues that, while Messick's unified theory of test validation aimed at (a) warning educational…

In adolescence research, the treatment of measurement reliability is often fragmented, and it is not always clear how different reliability coefficients are related. We show that generalizability theory (G-theory) is a comprehensive framework of measurement reliability, encompassing all other reliability methods (e.g., Pearson "r,"…

The Texas State University-San Marcos undergraduate healthcare administration program requires all bachelors of health administration (BHA) students to pass a comprehensive examination to demonstrate their knowledge of specific core competencies. This also demonstrates completion of their didactic coursework in order to enter a practical…

In educational testing, subscores may be provided based on a portion of the items from a larger test. One consideration in evaluation of such subscores is their ability to predict a criterion score. Two limitations on prediction exist. The first, which is well known, is that the coefficient of determination for linear prediction of the criterion…

Classical procedures for calculating the two indices of decision consistency (P and Kappa) for criterion-referenced tests require two testings on each child. Huynh, Peng, and Subkoviak have presented one-testing procedures for these indices. These indices can be estimated without any test administration using Ebel's estimates of the mean, standard…

Binomial models for domain-referenced testing are compared, emphasizing the assumptions underlying the beta-binomial model. Advantages and disadvantages are discussed. A proposed item sampling model is presented which takes the effect of guessing into account. (Author/CM)

The paper considers the problem of selecting the t best of k normal populations and simultaneously determining whether the selected populations have a mean larger than a known standard. Illustrations are given for selecting the t best of k examinees when the binomial error model applies. (Author)

Three item selection methods for criterion-referenced tests are examined: the classical theory of item difficulty and item-test correlation; the latent trait theory of item characteristic curves; and a decision-theoretic approach for optimal item selection. Item contribution to the standardized expected utility of mastery testing is discussed. (CM)

Mastery learning strategies and criterion referenced measurement tools perform a selective function in the classroom. The selective approach within the philosophical role of schools is discussed in terms of limited educational employment, competition, talent distribution, and the suggested attributes of good testing. (CM)

For some situations the beta-binomial distribution might be used to describe the marginal distribution of test scores for a particular population of examinees. Several different methods of approximating the maximum likelihood estimate were investigated, and it was found that the Newton-Raphson method should be used when it yields admissable…

On the basis of the characteristics of criterion-referenced tests, the contribution of German research to the development and application of criterion-referenced tests is discussed. (PN)

A continuum of item-writing methods is proposed ranging from informal-subjective methods to algorithmic-objective methods. Examples of techniques include objective-based item writing, amplified objectives, item forms, facet design, domain-referenced concept testing, and computerized techniques. (Author/CP)

Explains and contrasts the techniques and philosophies of norm-referenced (NRT) and criterion-referenced tests (CRT). NRTs are criticized for lack of useful information and control. CRTs are usually teacher-made and customized to fit the classroom needs, offering more control over test content, but few teachers are prepared to develop them. (SM)

Discusses the use of standardized test results as a guide to developing curriculum content and uses data gathered at Hellgate Elementary School, Montana, as an example. (JC)

The reliabilities of two types of measurement plans were compared across six hypothetical distributions of true scores or abilities. The measurement plans were: (1) fixed-length, where the number of trials for all examinees is set in advance; and (2) trials-to-criterion, where examinees must keep trying until they complete a given number of trials…
