Efforts of the National Academy of Sciences (NAS) as a contractor to the National Institute on Drug Abuse (NIDA) include: (1) assessment of the usefulness of naltrexone, a narcotic antagonist, in the rehabilitation of several types of opiate-dependent individuals; (2) assessment of any drawbacks to the use of naltrexone; and (3) appraisal of…

Applications, acceptances, and new enrollments in all graduate programs for the Spring 1974, Summer 1974, and Fall 1974 terms are tabulated. This report differs from previous editions in that it contains a complete set of trend tables that array data for 1972, 1973, and 1974 in a manner that should facilitate comparisons. Data are also provided…

Examples of the reports generated by the National Center for Higher Education Management Systems (NCHEMS) Student Flow Model (SFM) IA are presented. The SFM-IA is a tool for analyzing the historical movement of students between the various fields of study and student levels in an institution and for estimating the future enrollments in each field…

A sizable representative subsample of the standardization group for the Metropolitan Achievement Tests participated in both the Fall and Spring standardization programs. Fall and Spring test records were matched for all such pupils and Fall-Spring "growth expectancies" were derived. Additionally, the sample was split into three subgroups…

Under contract with the Oregon State Department of Education, Educational Testing Service (ETS) assisted in the preparation of a fourth grade reading assessment test based on, or modified from, Instructional Objectives Exchange materials. ETS produced test books, answer sheets, and all required ancillary materials necessary for test distribution…

Responses on both the state and trait scales of the State-Trait Anxiety (STAI) Inventory were examined under two conditions. The first condition presented a simulated real-life situation containing competitive and evaluative cues without directly suggesting faking and asked subjects to complete the STAI. After an intervening task, the STAI was…

Presented are the results of a project to test and evaluate the Conscious Synthesis of Development (CSD) method for treating stuttering which concentrates on both psychological and physiological aspects of the disorder. The report is organized into the following divisions: definition and psychophysiology of stuttering; historical overview; review…

The four purposes of this study were: (1) To compare two versions of a tailored testing model similar to one suggested by Kalisch (1974); (2) To identify levels of the variables within the two versions, which produce an efficient tailored testing procedures; (3) To compare, within each version, the results obtained when employing relatively small…

Two tailored testing models, specifying procedures by which the correctness of examinees' responses to a fixed number of test items are predicted by presenting as few items as possible to the examinee, were compared for their efficiency. The models differ in that one requires reconsideration of each prediction whenever additional information is…

A method for establishing minimal acceptable performance levels for criterion referenced multiple choice examinations is described and two procedures for evaluating its validity are discussed. The method involves assigning a priori item difficulties based on the similarity between the distractor and the correct response. In estimating the validity…

Performance testing often entails the usage of expensive, time-consuming measures in the quest for determining the level of performance on some desired behavior. It is concluded that a generalizability theory approach to dealing with departures from reality in testing can aid in the establishment of empirically-based choices of measurement…

This tenth annual report of national normative data on students entering college as first-time, full-time freshmen is part of an ongoing longitudinal study of the American higher education system. Its purpose is to determine the effects of college on students. Data for 1975 is based on responses from 186,406 freshmen entering 366 institutions;…

During the past few years the problem of bias in testing has become an increasingly important issue. In most research, bias refers to the fair use of tests and has thus been defined in terms of an outside criterion measure of the performance being predicted by the test. Recently however, there has been growing interest in assessing bias when such…

The study attempted to determine the roles of vocational and technical education as perceived by parents, teachers, school board members, school counselors, and students in Oklahoma. The Delphi technique was used to formulate the opinionnaire from responses of 320 randomly selected participants. The statements were ranked by the participants' mean…

This paper describes how the evaluation of teachers by principals is hampered by difficulties in communication. The 131 teachers and 33 principals questioned did not agree on how much teachers knew about the way they were evaluated. Nor did they agree on the frequency of evaluations; the teachers reported less frequent evaluation than the…
