The author discusses the role of speech and hearing specialists in dealing with language disordered children, and considers the uses and limitations of language tests. (LS)

Evaluated with 25 learning disabled (LD) and 25 non LD elementary level children was the Bayesian method to screen children for possible LD, an approach which uses the aggregation of data--objective test scores related to likelihood ratios and a known prior odds ratio. (Author/DB)

Some basic statistical concepts relevant to the teacher--mean scores, standard deviation, normal and skewed distributions, z scores, item analysis, standard error of measurement, reliability--and their use by the teacher are explained. (RM)

A discussion of appropriate ways of preparing students to take standardized tests is presented for school administrators. The point at which preparation practices move beyond the ethical depends on the inferences one wishes to draw from test scores. Inferences drawn from test scores are general in nature and will be inaccurate if instruction is…

This handbook serves as a guide for administrators and lead teachers in a staff development program for improving the quality of instruction in high schools in Oregon. The staff development program is divided into a 2-day basic training program and a 3-day advanced training program. In the first session, participants learn to establish learning…

The study evaluated the Woodcock-Johnson Psycho-Educational Battery (WJPEB) with 71 elementary grade learning disabled (LD) students. The following questions were addressed: (1) Are there significant discrepancies between ability and achievement, as measured by the WJPEB, for LD children, and if so, in what academic areas? (2) Are there patterns…

Guidelines for test developers and users are provided to insure that construction and selection of test instruments are conducted fairly. In addition to development and selection, issues of interpretation of scores; provision of information to test takers; and prevention of test bias based on race, gender, or ethnicity are addressed. Twenty-one…

Two of the most popular methods for obtaining equal-interval scales for educational measurement are discussed: Thurstone's method and Item Response Theory (IRT). Between-grade growth on these scales is compared; while unstandardized differences show different trends for the two scales, standardized differences that take standard deviations into…

This digest on test uses in counseling discusses the selection, administration, and scoring of tests; the interpretation of test results; and communication of results to clients. It examines such issues in testing as confidentiality, counselor preparation, client involvement in the testing process, computerized testing, and ethics. (NB)

The current status of banks of test items existing across the United States was determined through a survey conducted between September and December 1987. Item "bank" in this context does not imply that the test items are available in computerized form, but simply that "deposited" test items can be withdrawn for use. Emphasis…

This study investigated ways of making present and past results of the National Assessment of Educational Progress (NAEP) and other data sources maximally useful as science indicators and to recommend possible changes in instrumentation and procedures that may enhance future NAEP surveys for these purposes. Primary emphasis was given to reviewing…

This paper points out that there are certain generalizations about directions for guessing and methods of scoring that require that data be derived from random groups design. It supports the viewpoint that it is neither sufficient nor appropriate to make such generalizations on the basis of an analysis of scores obtained from the answer sheets of…

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…
