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.     

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.     

A Validity and Multiple Regression Study of Performance in the GEPI as a Predictor for Performance on the GED

This study attempts to determine the relationship between the subtests of the General Education Performance Index (GEPI) and the revised version of the General Educational Development Test (GED), and reports a technique whereby performance on the GEPI may be used to predict performance on the GED. Participants were men and women, aged 16 to 62, who were given the GEPI and then the GED. Multiple regression equations were generated to predict GED scores using age and each GEPI score. No significant correlation was found between age and GED scores or between age and GEPI scores, but a highly significant correlation (p > .001) was found between each GEPI subtest score and the subsequent score attained on the GED. Regression equations for each subtest and cross validation that demonstrated high predictive validity for each regression equation are reported.     

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.     

Predicting Success in Vocational Training By Using the GATB

This study examined the relationship between the General Aptitude Test Battery (GATB)and class performance of eleventh- and twelfth-grade high school students enrolled in the Current River Area Vocational School, Doniphan, Missouri. Teachers' grades were used as the dependent variable, and the nine independent variables were scores taken from the aptitude factors of the GATB. The stepwise multiple regression technique was used to determine the optimal set of predictors to be used in establishing a regression equation. The results of the project should help in counseling prospective trainees toward trade or shop areas and tentative vocational planning. If not used out of perspective, the G variable in the GATB was the best single predictor of success; the best combination of variables was the G, N, P, F, and M aptitude factors.     

GATB Aptitude Intercorrelations of Ninth and Twelfth Graders—A Study in Organization of Mental Abilities

This study was conducted to investigate the stability of interrelationships of the aptitudes of the General Aptitude Test Battery (GATB) during high school. GATB intercorrelations were obtained for comparable samples of 7,078 ninth graders and 6,167 twelfth graders from 168 schools. The matrices were significantly different, but the differences in individual correlations were small in size.     

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.     

The relationship between guardian certification requirements and guardian sanctioning: a research issue in elder law and policy

This study investigated the relationship between guardian certification requirements and guardian sanctioning in the state of Washington. A total of 377 files were examined. Findings show that 52.4% of guardians with an undergraduate degree or higher education are likely to be sanctioned compared with 42.2% with an Associate of Arts (AA) or Technical (Tech) degree, and 36.9% with a high school diploma (HS) or equivalency (GED). Guardians with an undergraduate or higher education are 1.88 times more likely to be sanctioned compared with GED or HS graduates (p < 0.05). However, 83.3% of GED or HS graduates are likely to have more severe sanctions compared with 76.4% undergraduate or higher education, and 47.7% with an AA or Tech degree, respectively. Guardians with an AA or Tech degree are 0.28 times less likely to have more severe sanctions than guardians with an undergraduate degree or higher education (p < 0.01). The results are discussed with respect to guardian registration, licensing, certification and quality; licensing and regulation of other professions; the limitations of the study; and the need for further research.     

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.     

Sustaining work force inclusion and well-being of mothers on public assistance: Individual deficit and social ecology perspectives

This study compared theoretical perspectives on the psychological and paid labor activity implications of mandating mothers initially on US welfare to participate in labor force activities. Data were collected that reflected these areas: government public policy interventions, family social ecology measures, mother’s psychological and human capital, and community capital. A quasi-experimental design was used, and multiple source data was collected over time. In the initial part of the study, 144 welfare mothers and one of their children between 9 and 13 years were interviewed. Results indicated that having high levels of individual human and psychological capital and lower levels of family social ecological barriers predicted higher levels of maternal paid labor market activity and psychological well-being. Using archival records, additional analyses involved a 32-month review of state records for nearly 1200 mothers initially on welfare. Results revealed that the lower one’s initial capital—either educational (lacking GED or high school diploma) or community-based (residents spending a high percentage of gross income on rent), the greater one’s economic dependence on public welfare, regardless of whether one was assigned to a welfare to work program or to a control group. Thus, mandating labor market activity as a government public policy was not effective as an isolated strategy to uphold employability over time. These results suggest that employers and government leaders need to provide individual human capital and community capital investments to sustain work force inclusion of low-income mothers.     

GATB Longitudinal Maturation Study

This article describes results of the first in a series of three large-scale longitudinal studies conducted by the U.S. Employment Service to increase the usefulness of the GATB for counseling high school students. The final sample consisted of 26,708 high school students. All were tested with the GATB in 1958, and those in the lower high school grades were retested in the twelfth grade. Results were as follows: (1) Stability coefficients were highest for the eleventh grade sample and lowest for the ninth grade sample. (2) Interval between initial testing and retesting had very little relationship to size of practice effect. (3) Maturation increases were largest between the ninth and twelfth grade and smallest between the eleventh and twelfth grade. (4) OAP stability was increased through use of a “band” around the cutting scores.     

A Review of the Nonreading Aptitude Test Battery

This article re-examines data from the Nonreading Aptitude Test Battery (NATB) and General Aptitude Test Battery (GATB) test manuals in light of some conventionally accepted psychometric considerations. The NATB standardization sample is adequate. However, the validity is open to question since the NATB demonstrates only a modest correlation with the GATB. It is recommended that caution be employed in relating NATB profiles to the Occupational Aptitude Patterns' norms. This is especially relevant since the NATB, lacking norms of its own, relies on GATB norms and its derived Occupational Aptitude Pattern (OAP).     

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.     

Comparison of vocational school graduates and dropouts

Graduates and dropouts from six vocational training programs were compared on data taken from school records and from their responses to a questionnaire. Results revealed that age, level of education, high school completion, marital status, physical or health disabilities, and GATB scores were not significant factors in distinguishing between graduates and dropouts in vocational training programs. Two significant factors were: (1) whether the vocational school offered the student's first choice of a vocational program, and (2) whether a student transferred from a college academic program to a vocational program or directly entered a vocational program without prior college academic work.     

Before and after entering school: The development of attention and executive functions from 6 to 8 years in Finnish children

In this 2‐year prospective follow‐up study we examined typical and atypical development of attention and executive function (AEF) across the transition to school. The NEPSY‐battery was used to evaluate the AEFs of the children before school at 6 years of age. Two subgroups, typical AEF (n = 25) and atypical AEF (n = 25), were formed according to the performance in AEF tasks. Children were assessed again at 8 years, when they were at the 2nd grade. The same subtests of the NEPSY‐battery and the ATTEX behavioral rating completed by a teacher were used. The effects of AEF deficits were compared with and without controlling for IQ. The group effect was significant in four out of the six NEPSY subtests used. The atypical AEF group had problems especially on subtests measuring motor inhibition both at the age of 6 and 8. The group‐time interaction effect was found in the subtest measuring attentional shifting. A catch‐up effect on shifting skills was observed in the atypical AEF group by the age of 8 years. In school at the 2nd grade, the early AEF problems were still observable, and related especially to inattention problems. Our results support the interpretation that inhibitory problems are at the core of executive dysfunction, that the problems are stable from preschool to 2nd grade, and that the effects of early AEF problems go over and beyond intellectual deficits. Our results also support the use of performance based measures of inhibition as an important part of the neuropsychological evaluation for school readiness.     

Chronic absence,eighth-grade achievement,and high school attainment in the Chicago Longitudinal Study

Although not as commonly reported as average daily attendance, chronic absence data may be of significant importance for understanding student success. Using data from 1148 participants in the Chicago Longitudinal Study, we assessed the associations of chronic absence in the early middle grades, grades fourth through sixth, with eighth-grade achievement and three measures of high school attainment including four-year graduation by diploma, graduation by diploma by age 21, and any high school completion by age 21. The rate of chronic absenteeism, defined here as students missing approximately 14 days of school or more in a year, was 15%. Using Ordinary Least Squares, probit regression, and inverse-probability-weighting regression-adjustment methods (IPWRA), results indicated that chronic absence in the early middle grades was negatively associated (d = − 0.17) with eighth-grade math achievement and reduced the probability of four-year graduation by diploma by 18 percentage points, graduation by diploma by age 21 by 17 percentage points, and any high school completion by age 21 by 11 percentage points. IPWRA yielded similar estimates. Coefficients varied by subgroup with males and children of mothers who completed high school experiencing more detrimental effects. Associations of chronic absence with outcomes are important to understand because school interventions and practices which begin early can be effective in reducing the prevalence of absenteeism.     

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.     

Structure of the Wechsler Intelligence Scale for Children--Fourth Edition among a national sample of referred students

The structure of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV; D. Wechsler, 2003a) was analyzed via confirmatory factor analysis among a national sample of 355 students referred for psychoeducational evaluation by 93 school psychologists from 35 states. The structure of the WISC-IV core battery was best represented by four first-order factors as per D. Wechsler (2003b), plus a general intelligence factor in a direct hierarchical model. The general factor was the predominate source of variation among WISC-IV subtests, accounting for 48% of the total variance and 75% of the common variance. The largest 1st-order factor, Processing Speed, only accounted for 6.1% total and 9.5% common variance. Given these explanatory contributions, recommendations favoring interpretation of the 1st-order factor scores over the general intelligence score appear to be misguided.     

Statistical significance and reliability of single-subtest and cluster deviation scores

Suppose one has a battery of K subtests and a composite for the battery is defined as the mean of the K standardized subtest scores. An individual's single-subtest deviation score is the difference between the individual's score on any single subtest and his composite score. A cluster deviation score is the difference between an examinee's average for a small set (cluster) of subtests and his composite. Formulas are given for the test of statistical significance of the individual's subtest or cluster deviation score and the internal consistency reliability of such deviation scores.     

General and specific self-esteem in late adolescent students: race x gender x SES effects

This study assessed the effects of gender, race, and social class on the general and area-specific self-esteem of high school students. One hundred and ninety-five high school students served as subjects in a 2 (gender: male, female) X 2 (race: black, white) X 3 (social class: low, middle and high) factorial design. The Rosenberg General Self-Esteem, the Piers-Harris Children's Self-Concept, and the Brookover Self-Concept of Ability and School Achievement scales were the measures of either general or specific self-esteem. Females, whites, and lower social class adolescents were consistently lower in their self-esteem scores than were males, blacks, and upper social class teenagers, respectively. White females were found to be lower in general and happiness self-esteem than all other gender by race subgroups. High SES white students were lower on the happiness and behavior self-esteem measures than black students and white middle-class students. Black males and white females were less confident in their school ability than were black females and white males.
