Predictive Indices of the GATB

The study reported here investigated the use of the General Aptitude Test Battery for identification and counseling of students in vocational and academic clases in Ohio secondary schools. Frequency distributions of the GATB aptitude scores were developed for 4,000 ninth- and tenth-grade boys and girls. A multiple regression analysis was performed using the aptitude scores of the GATB as the independent variables, and point hour ratio and single subject grades at the end of one year as the dependent variables. Freshmen and sophomore grade-point average separately and in combination were the criteria used to determine the predictive ability of the aptitudes of the GATB. The GATB was useful in the predictive role for ninth- and tenth-grade achievement in most of the areas studied.     

Measuring Manual Dexterity with the GATB: Wooden versus Plastic Pegboards

As part of a ten-year longitudinal study of vocational development being conducted in the Department of Vocational Education at The Pennsylvania State University, it was decided to administer the GATB to an entire ninth grade class of 1,050 boys and girls. Because both wooden and plastic pegboards were being used to assess GATB aptitude manual dexterity (M), it was decided to compare the scores obtained on the two different types of boards. Results of the study indicate that those students who were tested using the wooden boards performed significantly better than did students tested on the plastic boards. Converted score differences for aptitude M ranged from 3 to 26 points with an average difference of 11 points.     

USE OF THE GATB IN PREDICTING SUCCESS ON THE TESTS OF GENERAL EDUCATIONAL DEVELOPMENT

An attempt was made to determine how useful the General Aptitude Test Battery can be when used as a predictor of success on the Tests of General Educational Development. The General Ability and Verbal Aptitude subtests of the GATB were found to be the best predictors. Estimating the applicant's chance of passing the GED from the ‘G’ and ‘V’ scores was discussed.     

Differential Predictability: Selection of Handicapped and Non-handicapped

This research is concerned with the question of differential predictability of handicapped and non-handicapped subgroups. The specific question posed was: Is the performance of non-handicapped subgroups of skilled, clerical, and non-skilled workers more predictable than that of handicapped subgroups when aptitude measures are used as predictors? Correlations between scores on selected scales of the GATB and a composite performance criterion were obtained for each of the subgroups. Results showed a pattern of consistently lower validities for the handicapped which suggests that aptitude measures typically used in selection may not be appropriate for the handicapped, and that validity coefficients may be diluted by the inclusion of this subgroup with the non-handicapped in validity studies.     

GATB APTITUDE TESTING OF THE DEAF: PROBLEMS AND POSSIBILITIES

This study, based on aptitude testing of 408 deaf high school students, provides evidence that a modified version of the GATB is a useful instrument for measuring the occupational aptitudes of deaf individuals.     

A COMPARISON OF A DISADVANTAGED SAMPLE WITH A NATIONAL SAMPLE ON THE GATB

The GATB is widely used in making vocational decisions. The norms are based on a national sample tested in 1952. In the study reported here the GATB results of a sample of disadvantaged individuals were compared to the results of the 1952 sample. Significant differences were obtained for five variables: name comparison, computation, vocabulary, tool matching, and arithmetic reasoning. In each case the scores of the national sample were higher. The differences occurred on variables of an academic nature, although mean education was approximately the same in both samples. Some reasons for the differences are suggested in this article.     

USE OF THE GATB “G” SCORE FOR PREDICTING ACHIEVEMENT ON THE GED

The present study investigates the relationship of the GATB “G” with the GED. Practical and theoretical implications are involved. Making use of samples from the Las Vegas, Nevada population, the study compares scores of individuals administered the GED and GATB. A substantial correlation for prediction purposes was devised to illustrate the use of the GATB “G” to predict, by interval, an individual's position on the GED. The expectancy table helps guide the Vocational Counselor with a constructive tool whereby he advises the next steps of action for an educationally deficient or proficient client. The study recommends further replications to determine if such studies could guide agency policies whereby vocational counseling practice is improved and agency testing costs reduced.     

LINKING O*NET JOB ANALYSIS INFORMATION TO JOB REQUIREMENT PREDICTORS: AN O*NET APPLICATION

This is an exploratory study that examined the possible application of the job component validity (JCV) model to identify potential employee selection instruments and to determine job requirement levels from O*NET job analysis data, following a research paradigm established with the Position Analysis Questionnaire (PAQ). Job requirements were measured by mean aptitude test scores on the General Aptitude Test Battery (GATB), and the ratings on the O*NET Generalized Work Activities (GWAs) were selected as representative O*NET job analysis data. Multiple correlation coefficients ranging from .35 to .89 were found when predicting mean GATB test scores from GWAs. Similar to JCV research some 30 years ago, predictions were strongest for cognitive aptitudes and weakest for manual dexterity. The data were examined under both rational and cross-validated empirical models. The results have positive implications for the development of a database that would support JCV estimates derived from O*NET job analysis data and allow practitioners to use O*NET data to help identify useful employee selection instruments.     

Worker estimation of ability requirements of their jobs

A modified version of the Minnesota Job Requirements Questionnaire (MJRQ), representing the GATB aptitudes, was used by workers in 11 selected jobs to rate the ability requirements of their jobs. Worker MJRQ ratings were compared with supervisor MJRQ ratings. Modified Occupational Ability Patterns (OAPs) derived from worker ratings were compared with OAPs based on supervisor ratings, OAPs from expert ratings in the DOT, and OAPs from the empirical GATB approach. Reliability of worker MJRQ ratings was comparable to that of supervisor ratings. Comparisons of mean ratings and variability of ratings of workers in a job category with workers in other jobs, and with supervisors rating the same job, showed construct validity for worker MJRQ ratings, as did intercorrelations of the worker ratings. OAPs derived from worker MJRQ ratings compared favorably with OAPs derived from supervisor MJRQ ratings, from the DOT, and from the GATB. Differences among workers on variables such as satisfaction, age and tenure did not significantly affect their MJRQ ratings. Implications of the worker MJRQ ratings are discussed.     

USE OF APTITUDE SCORES AS PREDICTORS OF SUCCESS IN OCCUPATIONAL TRAINING UNDER THE MDTA

Results from studies utilizing the General Aptitude Test Battery (GATB) to predict success in specific vocational training programs authorized by the Manpower Development and Training Act of 1962 are summarized. The summary involves over 1,200 trainees from a number of states in a variety of occupational areas. Trainees from all included studies were combined and then subgrouped on the basis of number of years of formal education claimed. Good prediction was obtained for the 0–7, 8, 9, 10, 11, and 12 years-of-education groupings. The prediction obtained with the 13–16 years-of-education grouping is not at an acceptable level of significance, but this may be a result of the small sample available for this grouping. The results are seen as supporting Manpower Administration efforts to devise ways in which aptitude tests can be used to help match applicants with low levels of reported educational attainment with suitable vocational or training opportunities.     

A FORMULA FOR THE USE OF SUPPRESSION VARIABLES IN CORRECTING INDIVIDUAL RATINGS

D unér , A. & M agnusson , D. A formula for the use of suppression variables in correcting individual ratings. Scand. J. Psychol , 1962, 3 , 226–232.—Ratings of aptitude, ability or performance used for selection and/or prediction or as criteria for the estimation of the validity of other methods are often influenced by irrelevant factors. Two correction formulas based on a suppression variable have been derived. The relation between the correlation formula derived and the partial correlation formula is discussed, as well as the effect of the application of the formula on the estimation of differential validity.     

Social Determinants of Attitudes towards Women’s Premarital Sexuality among Female Turkish University Students

This paper explores the effects of demographic and attitudinal variables on attitudes toward women’s premarital sexuality in a sample of 277 undergraduate female students at Istanbul University, Turkey. The results of the research demonstrated that sexual attitudes best predicted the dependent variable in regression analysis. Once the variable sexual attitudes was excluded from the equation, mother’s education and personal religiosity were the best predictors of attitudes toward women’s premarital sexuality.

PREDICTING NAVY EFFECTIVENESS: EXPECTATIONS, MOTIVATION, PERSONALITY, APTITUDE, AND BACKGROUND VARIABLES

The purpose of this study was to identify predictors of performance within seven Navy occupational groups. Life history, expectations, motivation, personality, and aptitude variables were used as predictors of a 2-year effectiveness criterion for 7,923 enlisted Navy men and women. Results of multiple regression analyses showed that the most powerful predictors included: years of schooling, school expulsions and suspensions, the two Comrey Personality Scales of Social Conformity and Orderliness, arrests, age, General Classification Test (aptitude), and Peer Cohesion (expectations). Comparisons across groups indicated that the development of separate equations for each occupation was not supported. Recommendations were made to improve selection procedures and to change several aspects of the organization, suggestions which would be expected to increase rates of effective performance.     

An investigation into the factor structure of the General Aptitude Test Battery

The General Aptitude Test Battery (GATB), a 12-test battery purporting to measure nine occupation-related aptitudes, is one of the most widely used test batteries in the field of job selection. Despite its widespread use, however, little research has been carried out to investigate its factorial assumptions. The present study looks at the factorial structure of the GATB based on a large Irish sample. The results indicate that the GATB does not adequately measure nine specific underlying aptitudes, but four, more general, higher order aptitudes.     

The future of the General Aptitude Test Battery (GATB) for use in public and private testing

Recently, there have been concerns raised about the General Aptitude Test Battery, an instrument used extensively by state and federal agencies to assess those seeking jobs. These concerns involved the legality of the present GATB scoring system (from an equal employment opportunity standpoint), as well as the psychometric quality and validity of the instrument. For these and other reasons, the National Research Council was contacted by the Department of Labor to examine the present GATB. This paper will discuss those concerns raised about the GATB, the conclusions reached by the National Research Council, and recent developments in legislation which directly effect use of the GATB.     

Are math readiness and personality predictive of first-year retention in engineering?

On the basis of J. G. Borkowski, L. K. Chan, and N. Muthukrishna's model of academic success (2000), the present authors hypothesized that freshman retention in an engineering program would be related to not only basic aptitude but also affective factors. Participants were 129 college freshmen with engineering as their stated major. Aptitude was measured by SAT verbal and math scores, high school grade-point average (GPA), and an assessment of calculus readiness. Affective factors were assessed by the NEO-Five Factor Inventory (FFI; P. I. Costa & R. R. McCrae, 2007), and the Nowicki-Duke Locus of Control (LOC) scale (S. Nowicki & M. Duke, 1974). A binary logistic regression analysis found that calculus readiness and high school GPA were predictive of retention. Scores on the Neuroticism and Openness subscales from the NEO-FFI and LOC were correlated with retention status, but Openness was the only affective factor with a significant unique effect in the binary logistic regression. Results of the study lend modest support to Borkowski's model.     

Supervisor estimation of abilities required in jobs

The Minnesota Job Requirements Questionnaire (MJRQ) was developed and administered to supervisors of 11 selected jobs who rated the ability requirements of the job they supervised. The MJRQ represented each of nine GATB aptitudes by five items in a Likert-type format. MJRQ ratings were compared with expert ratings in the Dictionary of Occupational Titles (DOT) and Occupational Ability Patterns (OAPs) derived from administration of the General Aptitude Test Battery (GATB). Reliability of MJRQ ratings was shown by high Hoyt reliability coefficients. Comparison of mean ratings and variabilities of ratings by supervisors in a job showed construct validity for the MJRQ approach, as did intercorrelations of MJRQ ratings. OAPs derived from the MJRQ compared favorably with those derived from the GATB and DOT, showing promise for the parsimonious MJRQ approach to the development of OAPs.

Validation of intelligence and mechanical aptitude tests in selecting employees for manufacturing jobs

One hundred ninety-three manufacturing employees who produce electro-mechanical components participated in a concurrent criterion-related validity study. The employees were administered three tests: The Bennett Mechanical Comprehension Test (Form S); The Flanagan Aptitude Classification Test-Mechanics; and the Thurstone Test of Mental Alertness (Form A). Job performance was measured by a supervisor rating of fifteen job dimensions, assessed at two points in time separated by 60 days. Correlational and multiple regression analyses were used to assess the relationship between test scores and job performance ratings. The results revealed that the Bennett Mechanical Comprehension test was the best single predictor of job performance (uncorrectedr =.38), and the incremental gain in predictability from additional tests was not significant. The results were discussed in the context of the changing nature of manufacturing jobs and the inadequacy of conventional mechanical aptitude tests to be sensitive to these changes.
