Factor analysis was used to cluster the tests into composites based on

the underlying dimensions of ability in the ASVAB. A principal factor solution was rotated to simple oblique structure to achieve the following five

ability factors: verbal, analytic/quantitative, cler ical , mechanical , and

trade technical . These factors have high reliability and relatively low

intercorrelations. One last score test composite , called academic ability,

was added to the factorially based composites as an indicator of the abi lity

FOREWORD

The U.S. Army Research Institute for the Behavioral and Social

Sciences (

~ BI) has been responsible for the Army ’s research on the

Armed Services Vocational Aptitude Battery (ASV~B), which is utilized

for selection and classification of enlisted personnel. A parallel form

of this battery is administered to high school students who wish to be

tested to aid in general vocational planning .

This report describes the development of revised high school test

composite measures that are designed to be relevant to general vocational counseling dimensions rather than strictly functions of the

military job domain. The research was accomplished by personnel of the

ARI Personnel and Manpower Technical Area , one of whom, Dr. McBride , is

now with the Naval Personnel Research and Development Center at San

Diego. Work was done under Army Project 2Q163731A768 , Manpower Accession and Retention Systems , in response to requirements from the Deputy

chief of Staff for Personnel.

DEVELOPMENT OF FACTORIALLY BASED ASVAB HIGH

SCHOOL COMPOSITES

Requirement:

To develop revised Armed Services Vocational Aptitude Battery

(ASVAB) subtest composites for the specific purpose of high school vocational guidance .

Procedure :

The ASVAB (Form 5) administered to high school students consists

of 12 subtests . To develop subtest composites that would be most suitable for high school counseling, dimensions of ability underlying the

test battery were defined through the use of factor analysis. This

methodology is substantially different from previous sets of composites

developed to relate to specific military job groupings. The data analyzed were from a sample of more than 2,000 10th, 11th, and 12th graders

generally representative of the national population of high school

students.

Findings:

Five non-overlapping clusters of tests were found that best defined

each of five factors. The factors were (1) Verbal Ability--knowledge

of words and reading comprehension ; (2) Analytic/Quantitative Ability--

general reasoning and mathematical knowledge; (3) Clerical Ability——

speed and accuracy in using letters and numbers; (4) Mechanical

Ability—-understanding mechanical principles and visualizing objects

in three-dimensional space; and (5) Trade Technical Knowledge--relevant

to automotive information and shop practices. A sixth composite , not

dr awn from the factor analysis, called Academic Ability , helps the

counselor understand the level of education or training most appropri—

ate to the student.

Utilization of Findings:

The new composites became operational in the high school testing

program in school year 1977—78.

DEVELOPMENT OF FACTORIALLY BASED ASVAB HIGH

SCHOOL COMPOSITES

INTRODU CTION

The Armed Services Vocational Aptitude Battery (ASVAB) is a set

of short, relatively homogeneous, ability tests designed for two broad

applications : (1) selection and classification of applicants for

military enlistment, and (2) vocational guidance in high schools.

Three forms of ASVAB are currently in operational use; ASVAB—5 is used

in a testing program offered to high schools nationwide, and ASVAB-6

and ASVAB-7 are used for military entrance examining purposes. This

report is concerned with ASVAB-5 , the high school testing battery ,

the scores of which are provided to school guidance specialists for

individual counseling purposes. The report will present in brief detail the development of an improved set of composites to be used for

counseling in the high school program.

ASVAB—5 consists of 12 subtests listed in Table 1. The scores

reported to counselors and students are composites formed from weighted

sums of the subtest scores. In the 1976—77 school year, six composite

scores were used : Electronic/Electrical (EL), Communications (CO),

General Technical (GT), Motor Mechanical (MM), General Mechanical (GM),

and Clerical/Administrative (CL). The definitions of these composites

in terms of their constituent ASVAB subtests are given in Table 2.

The respective composites are formed by summing the raw scores on the

subtests defining them.

METHOD

The original ASVAB-5 composites had been defined judgmentally on

the basis of the ability each subtest was known to measure (using empirical relationships in the research of the services for predicting

success in military training and work). These compositing judgments,

although made by experts, were necessarily subjective . One aim in defining a new set of composites was to stress objective analytic methods.

Factor analysis of the intercorrelations among the 12 ASVAB subtests

was used to determine common ability dimensions underlying the interrelationships among the subtests.

The data analyzed consisted of the matrix of ASVAB—5 subtest

intercorrelations obtained by Fletcher and Ree ,

1 and listed in Table 3.

This correlation matrix was obtained in a sample of 2,052 volunteers

approximately equally distributed among 10th-, 11th-, and 12th-grade

males and females in what was described by Fletcher and Ree as “a geographically stratified selection of schools interested in vocational

testing, in numbers approximately proportional to the national mixture of public versus private, and urban versus suburban versus rural

schools” (p. 13).

The matrix was factor analyzed using a principal factor solution

(with estimated coimnunalities) followed by rotation to oblique si~%ple

structure using a direct oblimin solution with delta set at zero.

RESULTS AND DISCUSSION

A five-factor oblimin solution was chosen ; the resulting factor

pattern weights for each subtest variable are presented in Table 4.

Each row of the table contains the loadings of t

1.e five factors on

the corresponding variable, i.e., the contributions of each factor to

the variable . Table 4 shows that the first factor had high loadings

on three ASVAB subtests; the remaining four factors each loaded high

on a unique set of two ASVAB subtests. The sets of subtests for which — each factor was most salient were all readily interpretable. For in—

stance , Factor 1 was the predominant factor in subtest WK (Word Knowledge) , GS (General Science) , and GI (General Information) ; all three

of these require comprehension of verbal material. Factor 2 was most

important for subtests AD (Attention to Detail) and NO (Numerical

Operations) , both of which stress speed and accuracy in simple processing of letters and numbers. Factor 3 was most salient in subtests MX

(Mathematics Knowledge ) and AR (Arithmetic Reasoning), subtests which

require the application of quantitative concepts and abstract reasoning. Factors 4 and 5 were just as readily interpretable in terms of

the subtest variables to which they contributed most heavily-—spatial

relations and mechanical comprehension for the former, automotive repair

and shop practices for the latter.

The set of ASVAB-5 subtests to which each factor contributed

most heavily may be considered as a cluster. The five clusters were

used to define new ASVAB-5 composites; these are described and interpreted in Table 5. There is no overlap in these five composites; i.e.,

no subtest appears in more than one composite. Every subtest except

Electronics Information (El) is represented in a composite; El is obviously factorially complex , with heavy loadings being contributed by

three factors——verbal , trade technical, and mechanical. Each composite

is readily interpretable in terms of a basic and relatively specific

ability. A sixth composite , not drawn from the factor analysis, was

added to provide the counselor with an indication of general ability

and academic promise. This composite , Academic Ability , consists of

subtests WK and AR and has a long history of application in military

settings and in commercial test batteries.

Table 6 contains the intercorrelations among the new ASVAB-5 cornposites, along with their internal consistency reliability coefficients.

These reliabilities are based on the subtest internal consistency reliabilities obtained in the original ASVAB—5 standardization sample

(N = 610) reported in Jensen , Massey , and ‘Jalentine.3 These coeff icients were then combined using a correlation of sums procedure to

obtain the composite reliabilities. As Table 6 shows, the mean intercorrelation among the five specific ability composites is 0.51. The

correlations of the five specific-ability composites with the general

ability composite, AA , are shown separately ; these five correlations

average 0.67. The reliabilities of the six composites are all high;

the average is .90, and the range is from .88 to .92.

CONCLUSIONS

• As described above, a set of six new ASVAB-5 composites was developed. Five of the composites are measures of differential abilities derived from the results of factor analysis; the sixth composite

was added to provide a general measure of academic ability. The f ive

differential ability composites in the aggregate utilize all the

ASVAB-5 stthtests except Electronics Information , with no subtest appearing in more than one composite . The differential ability composites have desirably low to moderate intercorrelations, while

each composite has high reliability . The composites are readily interpretable as measures of differentiated abilities. This, combined

with their high reliability, should make them useful for describing

profiles of students’ abilities and for vocational guidance counseling.
