A STUDY DESIGNED TO IDENTIFY SOME OF THE DIFFERENCES BETWEEN THE RESPONSES ON THE GATES ADVANCED PRIMARY READING TEST AND THE KINDS OF RESPONSES OBTAINED FROM AN INFORMAL READING INVENTORY (IRI) IS REPORTED. SUBJECTS WERE 65 THIRD-GRADE PUPILS IN WEST BABYLON, NEW YORK. PUPILS AT THE SAME INSTRUCTIONAL LEVEL SCORED HIGHER IN THE RECOGNITION TEST…

Presented is a summary of an Educational Testing Service (ETS) review of mean scores on the Graduate Record Examination (GRE) of candidates for graduate study in science and engineering fields for the period 1970-1975. Test results were found to have remained essentially stable over the period within each particular field. Significant differences…

The major purpose of this work is to provide information for teachers about intelligence testing; more specifically, how the revised Wechsler Intelligence Scale for Children (WISC-R) can be used practically. The purpose is not to make teachers into testers, but rather to make them more sophisticiated users of the information that they obtain from…

Diagnosticians of handicapped children need to provide the teacher with quantitative and qualitative descriptions of how a child succeeds to bridge the gap between evaluation and the prescriptive program. The child's performance and the demands of the task should be delineated. Variables of development influenced by the impairment should be…

Some aspects of test reliability are discussed. Topics covered are: (1) how high should a reliability coefficient be?; (2) two factors affecting the interpretation of reliability coefficients--range of talent and interval between testings; (3) some common misconceptions--reliability of speed tests, part vs. total reliability, reliability for what…

In this paper, a new item analysis index, e, is derived as a function of difficulty and discrimination to represent item efficiency. Item discrimination in this paper is not independent of item difficulty, and it is demonstrated algebraically that the maximum discriminating power of an item may be determined from its difficulty. Item efficiency is…

This is a presentation of a new method for interpreting the Ohio Vocational Interest Survey (OVIS) using visuals. The OVIS, administered in 43 high schools in San Diego County, California, was intended to complement the existing school guidance and counseling programs by providing the students with their measured and expressed occupational…

The General Achievement Profile described in this article is used for making visual comparisons of a child's test performance scores through shadings on graph bars. The profile is intended as a counselor aid for use during an individual test interpretation session. (Author)

Ordinal measurement is the rank ordering of individuals in a population. For ordinal measurement, the concept of an individual propensity distribution is his or her true score. Estimation of, as well as other aspects of the distribution, are discussed. (Author/JKS)

Finding and interpreting lower bounds for reliability coefficients for tests with nonhomogenous items has been a problem for psychometricians. This paper presents a mathematical formula for finding the greatest lower bound for such a coefficient. (Author/JKS)

Presents a study of the identification of distinct dimensions within Rotter's Internal-External Control Scale. Five hundred college seniors served as subjects. (BD)

Psychological evaluations were used to identify shortcomings and suggest improvements in a computerized system for interpreting scores on the Sixteen Personality Factor Questionnaire and the Clinical Analysis Questionnaire. Results supported the accuracy of the computerized system, but revealed gaps in the information provided and suggested…

This paper presents the characteristics, properties and development of the National Reference Scale for reading. This new scale is the result of a reanalysis of the Anchor Test Study data using Rasch model procedures, in an effort to produce equated scores among all reading tests included in that study.
