This memorandum reports results of an analysis designed to obtain answers to the following questions: (1) How does the Overall High School Average compare with Converted Rank in Class as a predictor of Freshman Year Grades in college? and (2) Will more detailed information provided by analysis of high school records by subject help to improve…

The primary purpose of this study was to obtain estimates of the human attribute requirements of the job elements of the Position Analysis Questionnaire (PAQ). A secondary purpose was to explore the reliability of job-related ratings as a function of the number of raters. A taxonomy of 76 human attributes was used and ratings of the relevance of…

Recent studies have shown that in heterogeneous populations differential validities are often found in the population subgroups. In the light of the increasing societal emphasis on higher education, the valid prediction of academic success for all racial groups has become a necessity. This study is concerned with the differential validity for…

There were three objectives of a revision and validation of the Iowa Algebra Aptitude Test (IAAT): (1) to reduce the importance of speed; (2) to improve the quality of the existing items; and (3) to replace a subtest with one of potentially greater predictive validity. The last of these goals involved the development of a new subtest composed of a…

Measurement properties of the written rules tests were examined to determine their suitability for assessing driver knowledge and skill. It was concluded that the tests, as measurement tools for granting or renewing a driver's license, were not adequate. Recommendations for test improvement and a sample test copy are included. (AG)

Evidence indicates that college grades have increased on the average and that the college-bound population has decreased in traditional kinds of academic skills, based on observed declines on the Scholastic Aptitude Test (SAT) and the American College Test (ACT). But the relationship between these traditional skills and grades appears not to have…

Three quantitative measures which assess instructional material in terms of the rationale of adapting are reported. The first index is termed the consequence ratio, which evaluates diagnostic items in terms of how effectively time is used. The second measure, termed predictive validity, evaluates the accuracy of diagnostic test predictions. The…

The authors administered the Isolation Symptomatology Questionnaire to persons living in Antarctica who were either well or maladjusted to their environment. Eliminating those items not discriminating between the two groups, the authors constructed a new isolation scale. (SE)

The scores of 537 14-year-old students in Nigeria on the Raven Progressive Matrices were correlated with their scores on an achievement test, to provide an estimate of the predictive validity of the Raven. Results indicated low validity for this usage. (Author/JKS)

The HEW National Strategy for Youth Development Model (OYD), which serves as a basis from which to predict associations among various dimensions of juvenile delinquency, was empirically tested in a sample of 5,994 12 to 19-year-olds by means of several self-reported scales measuring OYD variables.

The Myers Briggs Type Indicator is a self-report inventory developed to measure variables in Carl Jung's personality typology. The four personality scales measured by the instrument, and the scoring process are described, and an extensive review of the intercorrelation, reliability, and validity research is presented. (Author/MV)

Laws committing dangerous sexual offenders indefinitely are legitimate only insofar as "dangerousness" can be predicted and treated. Yet most critical studies have concluded that not only has predictive accuracy not been demonstrated but also that such accuracy cannot be achieved. The authors argue that any conclusion at this time is premature.…

The learned helplessness model of depression predicts that any effective treatment for reactive depression should also reverse performance deficits associated with experimentally induced helplessness, and vice versa. This study tests that prediction with college students who were exposed to experimental manipulations designed to induce…

This study examines the validity of high school grade point average (GPA) and of the verbal and mathematical portions of the Scholastic Aptitude Test of the College Entrance Examination Board, as predictors of college performance over an eight year period. (Author/DEP)

Examines the predictive validity of the Scholastic Aptitude Test and high school achievement when predicting college freshmen grades. Results show that females are more predictable than males and the ability to predict college grades from these two variables seems to be decreasing. (Author/DEP)
