Ten item discrimination indices, across a variety of item analysis situations, were compared, based on the validities of tests constructed by using each of the indices to select 40 items from a 100-item pool. Item score data were generated by a computer program and included a simulation of guessing. (Author/CTM)

Two kinds of WISC-R short forms, item reduction and subtest reduction, are reviewed in terms of their ability to meet these criteria of adequacy: a significant correlation between the full scale IQ and the short form IQ, a non-significant difference between the full and short form mean IQ, a low percentage of IQ classification changes resulting…

Item-test correlations are compared to item test-retest correlations as measures for selecting items in test construction. The author concludes that the item test-retest method is superior for item analysis which aims at getting shorter tests while maintaining test stability. (Author/JKS)

The advantages of using psychometric thoery to design short forms of intelligence tests are demonstrated by comparing such usage to a systematic random procedure that has previously been used. The Wechsler Intelligence Scale for Children Revised (WISC-R) Short Form is presented as an example. (JKS)

Since grade-appropriate levels of standardized achievement tests must frequently be used in Elementary and Secondary Education Act Title I evaluations, there may be large discrepancies between test difficulty and the achievement level of those being tested, with resultant inaccuracies in the scores. Procedures based on the Rasch scaling model were…

Three methods of item selection were used to select sets of 38 items from a 50-item verbal analogies test and the resulting item sets were compared for internal consistency, standard errors of measurement, item difficulty, biserial item-test correlations, and relative efficiency. Three groups of 1,500 cases each were used for item selection. First…

This compendium is designed to assist vocational educators in selecting appropriate testing instruments to measure the learning outcomes of their programs. It presents by occupational area basic information on more than 150 validated measures and lists more than 1,200 additional entries in the Vocational Education Curriculum Materials (VECM)…

This guide is designed to serve as a reference to assist providers of Job Training Partnership Act-funded programs in selecting appropriate interest, aptitude, and pre-employment and job readiness tests. Descriptions of 53 interest tests, 38 aptitude tests, and 37 pre-employment and job readiness tests are provided. Each description contains…

The materials presented were developed for use in a series of conferences on testing and instruction sponsored by the National Institute of Education, with the United States Office of Education, the UCLA Center for the Study of Evaluation, and a network of research and development agencies. They are intended for use by school practitioners and…

Examines the increase in popularity of objective testing in the United Kingdom and addresses some of the accompanying academic issues. Reports on a case study of test production and implementation to illustrate issues of time costs and benefits. Discusses question styles, marking schemes, and the problem of guesswork. (MJP)

The development of the Student Selection Battery for the Beginning Teacher Evaluation Study is described. This battery, which measures reading and mathematics achievement in second and fifth grade students, will be used to select target students for the study of teaching effectiveness. Methodological considerations included: the limited amount of…
