The effect of stratified sampling of items based on item difficulty and/or interitem correlations on the estimation of test score distribution parameters using multiple matrix sampling was studied. Results indicated that stratification did not consistently improve the stability of parameter estimation. (Author/JKS)

It has been argued that item variance and test variance are not necessary characteristics for criterion-referenced tests, although they are necessary for norm-referenced tests. This position is in error because it considers sample statistics as the criteria for evaluating items and tests. Within a particular sample, an item or test may have no…

Achievement tests which are specifically linked to an instructional program and have been developed in relation to an objectives base and/or to an item generation rule are considered, as well as student response data. Three types of studies are outlined and the kind of procedures thought useful illustrated. As various methods for examining…

As an alternative to a classical test theory basis for criterion-referenced test construction, it is proposed that a strict item-sampling model be used. The computer's role in such a model is outlined. The assumptions of the model are carefully defined and its properties reviewed. The relationship between mastery criteria and such sampling plans…

Technical considerations associated with item selection and reliability assessment are considered in relation to criterion-referenced tests constructed to provide group information. The purpose is to emphasize test building and the evaluation of test scores in program evaluation studies. It is stressed that an evaluator employ a performance or…

A general process for testing the feasibility of applying alternative mathematical or statistical models to the solution of a practical problem is presented and flowcharted. The system is used to compare five models for test equating: (1) anchor test equating using classical test theory; (2) anchor test equating using the one-parameter logistic…

Criterion-referenced testing is defined and some of its background is discussed. A distinction is made between criterion-referenced scores, norm-referenced scores, cut-off scores, criterion scores, criterion variables, and content-standard scores. The relationship between norm-referenced information and criterion-referenced information is…

Mastery tests are analyzed in terms of the number of skills to be mastered and the number of items per skill, in order that correct decisions of mastery or nonmastery will be made to a desired degree of probability. It is assumed that a random sample of skills will be selected for measurement, that each skill will be measured by the same number of…

The existence of criterion-referenced (CR) measurement is questioned in this paper. Despite beliefs that differences exist between two alternative forms of measurement, CR and Norm Referenced (NR), an analysis of philosophical and psychological descriptions of measurement, as well as a growing number of empirical studies, reveal that the common…

A central problem for the user of domain-referenced tests in instruction is deciding who has passed and who has failed. Two procedures were presented and discussed. The first, employing classical test theory, was found to be more useful for larger domains and where the passing standard is 70 percent or less. The sampling procedure suggested by…

An achievement testing framework is being developed by the Los Angeles Unified School District to assess the educational progress of 14,000 secondary level compensatory education students with something other than standardized tests. The technique of multiple matrix sampling was applied to the use of large item domains in the subject area of…

A technology for domain or criterion referenced testing was developed to evaluate the Minnesota Mathematics and Science Teaching Project (MINNEMAST) in grades K-6. The venture was influenced by the low achievement of MINNEMAST students on standardized tests. After instructional objectives were selected and operationally defined, corresponding test…

The 1976 Educational Testing Service (ETS) Invitational Conference served as a platform for individuals who have been prominent in educational measurement and research to present their views on issues surrounding the testing controversy. The 1976 ETS "The Testing Scene: Chaos and Controversy," presents a historical review of events surrounding the…
