ABSTRACT 
Human differences and how these differences affect people’s daily lives have been, for a 
long time, the subject of interest among personality psychologists. Thus, an understanding 
of the relationship between personality traits and career interest is very important. The 
objectives  of  the  current  study  were:  First,  to  investigate  the  relationship  between 
personality traits of extraversion and agreeableness and career choices, secondly, to find 
out if within a personality trait, there were variations by levels of academic ability in 
career choices, and finally, to find out whether career choices differed between boys and 
girls of the same personality trait. A sample of 369 Form IV students, of whom 161 were 
males, and 208 were females completed Extravert-Introvert Personality Scale, Agreeable-
Less Agreeable Personality Scale, and Career Check List.  
 
The data were subjected to statistical analysis using Statistical Package for the Social 
Sciences (SPSS), Version 15.0. The findings showed that 62% of the introverts, 61.9% of 
the agreeables, and 55.6% of the extraverts chose computation skills occupations. The 
findings further revealed that, high academic ability subjects chose occupations in science 
related fields by 67.4% of the introverts, 66.3% of agreeables, 62.0% of less agreeables, 
and 59.8% of the extraverts. Low academic ability respondents chose occupations within 
social services, by about 59.4% of extraverts, 56.5% of introverts, and 54.7% of the less 
agreeables. On the other hand, about 63.5% of the agreeables with low academic abilities 
chose computation skills occupations. It was further revealed that there were no sex 
differences within extraversion personality trait in career preferences, while the study 
showed sex differences within agreeableness personality trait. 
 
It has been recommended that the best way to make students choose occupations which 
match their personality traits, sex, and academic ability, was through the establishment of 
a  proper  occupational  and  educational  guidance  and  counselling  services  in  school 
environments.
