The present study investigates the Perception of Ability Scale for Stu
dents (PASS) which is purported to measure six academic self-concept d
ynamic factors evident in children. Although previous analyses of PASS
among New Zealand children have suggested only Penmanship/Neatness su
bscale did not yield a significant effect, corresponding analyses amon
g non-Western children have not yet been undertaken in any satisfactor
y manner. To this end, the present article, reports the treatment by t
wo-way analyses of variance for the PASS on an African sample of 204 F
orm 2 or Grade 6 students enrolled in various elementary schools. The
results suggest the scale does not appear to have a ceiling effect whi
ch prevents differentiation of normally-achieving and learning-disable
d groups from those of gifted ones. The results also indicate that in
comparison with normally-achieving children, the learning-disabled (LD
) children are characterized by significantly more negative perception
s of ability and negative academic self-concept, along with tendencies
towards learned helplessness and lower achievement expectations for f
uture success in school. The Perception of Ability Scale for Students
is not only a new addition to the field of academic self-concept measu
rement, but also a major breakthrough for assessing children's cogniti
ve-motivational variables without the difficulties associated with sel
f-report questionnaires. Nevertheless, the degree of variation across
both studies and samples suggests that further refinement of the PASS
is required in order to improve its reliability and robustness.
