This chapter introduces theory that undergirds the role of testing adaptations in assessment, provides examples of item modifications and testing accommodations, reviews research relevant to each, and introduces a new paradigm that incorporates opportunity to learn (OTL), academic enablers, testing adaptations, and inferences that can be made from…

Study compares Wechsler (WISC-R) profiles of special-education students to seven core types distinguished primarily by levels of global ability. More than 96% of these students were found to be similar to one of the core types considered to be common variants of normal intellectual ability. Based on data, it is recommended that "no way"…

The unique conceptual framework and language of generalizability theory are presented. While this chapter is relevant to any area in which generalizability theory is applicable, it emphasizes evaluation research, and most examples come from that area. (Author/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)

Teachers need valid information to judge the types of programs, instruction, and colleges best suited to students. Teachers appear to support the use of standardized tests to provides some of that information. Abolishing such tests may lead to dependence on more subjective measures, resulting in inequities in placement and selection. (FG)

Research on the potential effects of different item arrangement schemes on item statistics is reviewed for three separate periods. Earliest studies investigated the simple main effect of item order on test performance. The late 1960s emphasized interactions between item order and examinees' characteristics. Current concern focuses on item…

A review of the development and innovation of testing at the higher education level focuses on Ralph Tyler's testing emphasis on the educational process and the objectives of instruction, a precursor to the current trend of integrating formative evaluation into the curriculum development process.

An empirical review of test items is described as an essential step in criterion-referenced test development. The concept of test items' instructional sensitivity is introduced, and research is briefly reviewed which describes four theoretical contexts in which instructional sensitivity indexes have been observed: criterion-referenced; classical…

Student test scores are increasingly used to judge the competence of the educational enterprise. Exaggeration of scores is the result of directing attention away from the individual student achievement to the average scores of schools, districts, and states. Implications and recommendations are discussed. (BJV)

The goal of test item writing is to create measures of the true achievement dimensions desired, not extraneous abilities or related skills. To encourage university instructors to apply newer test item writing technologies to test construction for course examinations, this paper: (1) sets forth basic principles for quality item writing; (2) reviews…

During a three-year project (1977-1980) on computerized adaptive achievement testing, item characteristic curve theory (ICC) and adaptive testing strategies designed almost exclusively for ability testing were applied to achievement testing. Adaptive techniques substantially reduced test length without reducing quality, when applied to three…
