Academic performance in KCSE in almost all the subjects offered has been low in Roysambu
County. However, the major factors contributing to this trend have not been clearly
understood. This therefore limits the ability of educational stakeholders to improve the
performance in KCSE. The purpose of this study is to investigate if home based factors,
discipline, teaching approaches and learning resources influence students? performance in
KCSE. Four research questions have been formulated to guide the study. The target
population for this study therefore constituted about 750 (2013) form 4 students, 145
teachers. All the head teachers and Form Four class teachers of the sampled seven schools
will be purposively included in the sample of respondents. The research used a descriptive
cross-sectional survey design. Stratified sampling technique was used and data was collected
using structured questionnaires. Statistical package for social sciences (SPSS) was used to
analyze data that was then presented in tables, bar charts and percentages. The findings
shows that all the teaching approaches are employed and also the teaching facilities and
resources are adequate for schools to accomplish their mandate. The home environment is
also conducive for students? performance .Despite all that, discipline has been concluded to
be a negative influence on performance. Recommendations drawn from the analyzed data are
discipline should be improved, provision of in-service courses for principal and teacher on
new teaching methods and parent sensitization on importance of education. Relevant
educational players may adopt the findings of the study. The findings may also be used as a
