ABSTRACT
-
The study reports correlations between student scores
-
on the general technical composite of the Armed Services Vocational
Aptitude Battery and cumulative grade point averages. Data were
collected on 911 juniors and seniors selected,from a sample at 22
high schools in the San Antonio, Texas, metropolitan area. The
general technical score was found. to significantly relate to overall
academic performance for 19 out of the 22 samples, with a media rank
order correlation coefficient_ (rhorof .44. Results indicate that the
level of relationship was not differentially affected by
school-specific ethnic group composition, school expenditures, or
average teacher/pupil ratio. Since socioeconomic levels represented
in the various samples go from the highest to the lowest ranges,
limited generalizations may be meaningful to other school districts
with similar diverse populatilans. The report is designed for
reference by high school counselors, service test administrators, and
educational specialists as a supplemental guide to the interpretation
of Armed Services Vocational Aptitude Battery results in local
guidance and counseling. programs.

ABSTRACT
This Technical Research Note reports correlations between stu-
dent scores on the General Technical (GT) composite of the Armed
Services Vocational Aptitude Battery and cumulative grade point
averages (GPAs). Data were collected on 911 juniors and seniors se-
lected from a sample at 22 secondary schools in the San Antonio)
metropolitan area.
The GT score was found to significantly relate to overall academic
performance for 19 out of the 22 samples, with a median rho of .44.
Results indicate that the level of relationship was not differentially
affected by school-specific ethnic group coemposition, school ex-
or average teacher/pupil ratio.

Neither the samples used nor conclusions presented in this study
should be construed as representative of high schools throughout the
country. Since socio-economic levels represented in the various
samples go from the highest to the lowest ranges, limited generaliza-
tions may be meaningful to other school districts with similar diverse
populations.

civilian academic sector. Additional studies will further assess re-
lationships across various grade levels, in differidg types of training
