This study was designed to determine (a) age and gender variations in the m
ultiple areas of self-concept, and (b) relations between these dimensions o
f self-concept and scholastic measures. The samples comprised 274 students
attending three co-educational high schools in Khayelitsha, Cape Town, Sout
h Africa. Although a few statistically significant effects of age and gende
r on global and domain-specific self-concepts were found, the differences a
ppeared to be of little qualitative significance. The size and pattern of r
elations with scholastic measures was weak. However, further investigations
from an African context are necessary to provide additional support for th
e claim that self-concepts are minimally influenced by human conditions suc
h as age and gender and that relationships between various facets of self-c
oncept and measures of academic achievement are weak.
