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…

This speech discusses performance contracting as educational research, notes some evaluation problems, and proposes solutions to these problems. The term performance contracting, according to the report, denotes an administrative rather than an instructional innovation. The author observes that the understanding of instruction and learning derived…

Empirical results are presented as regards the implementation of a latent-trait psychometric model by means of conditional maximum likelihood estimation. Items are scored polychotomously into varying numbers of nominal categories and the test and item characteristic curves and information functions are examined. It is concluded that scoring items…

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…

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…

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…
