Abstract:
Analysis of academic performance reports for Kenya Certificate of Secondary Education
(KCSE) in Nairobi County has been slanted towards the poor grades. This poses a threat to
the educational sector, which is an imperative pillar in the realization of productive labor
force. Determinants of career aspiration are presumed to have influenced students’ academic
performance. This study investigated the relationship between selected determinants of career
aspiration and academic performance of public schools’ students in Nairobi County. Specifically, the study investigated the relationship between levels of career aspiration and
academic performance, school type and academic performance, academic motivation and
academic performance and academic self-efficacy and academic performance. The study
adopted a correlation research design. The sample size consisted of 397 respondents drawn
from 26477 form four students who were registered candidates for 2017 examination. The
research instruments included questionnaire and document analysis. A sample size of 40
students (10% of the actual sample) was used for the pilot study. Purposive sampling was
used to select Nairobi County and form four students while proportionate stratified sampling
technique was used to select 12 schools from the 84 public secondary schools in Nairobi
County. Random sampling technique was employed to select the 397 students from the
selected schools. The Self-determination and the Social Cognitive theories formed the
theoretical framework in this study. Reliability was tested by computing Cronbach alpha
coefficient (α).The Academic Motivation Scale was adapted to measure academic motivation
of the students. Academic Self-efficacy Scale was adopted to quantify the students’ academic
self-efficacy. Student’s academic performance was measured by use of the standardized
KCSE national examination results of 2017. Collected data was analyzed using both
descriptive and inferential statistics in line with the study objectives. The null hypotheses
were tested using Chi-Squire (χ2) and Pearson Product Moment Correlation Coefficient (r)
tests. Statistical Package for Social Sciences (SPSS) aided the data analysis. The findings
indicated some evidence of a significant relationship between academic performance and
career aspiration, school type, academic motivation and academic self-efficacy. All the tests
were carried out at.05 level of significance. On testing the null hypothesis that there was no
significant relationship between the students’ level of career aspiration and academic
performance, Pearson chi-square of 0.019 was attained. Regarding the relationship between
school type and academic performance, Pearson chi-square of .000 was achieved. Pearson
Product Moment Correlation Coefficient (r) of .000 was acquired in the test of the
relationship between academic motivation and academic performance. Additionally, Pearson
Product Moment Correlation Coefficient of .002 was also reached in the test of the
relationship between academic self-efficacy and academic performance of the students. Since the probability the tests were less than α-value (0.05) all the null hypotheses were
rejected at 95% level of confidence denoting that the students’ academic performance was
influenced by career aspiration, type of school the students attended, academic motivation
and academic self-efficacy. The study concluded that career aspiration and its selected
determinants influenced students’ academic performance in 2017 KCSE exams. A major
implication and recommendation of the study was that all stakeholders in education should
validate and foster the development of career aspirations, academic motivation and academic
self-efficacy among the students. All schools’ climates should be made conducive for
students’ utilization of their full academic potentials. Further research should also consider
other determinants of career aspiration such as quality and quantity of career guidance
available to students, schools’ resources and facilities, parental and teachers’ characteristics, teaching pedagogy, students’ personality and their relationship with academic performance of
the students.
