Management practices are an important ingredient in an organization. They offer a unique environment needed to attain set goals, create a good public image and build a productive relationship among the stakeholders. The main aim of this study was to determine the influence of teacher satisfaction on the academic performance of learners in public secondary schools in Imenti North sub-county, Meru County. The study was based on organizational theory, which was developed by Jaques in 1951. The study adopted a mixed methods methodology where both quantitative and qualitative methods were employed. The sampling unit consisted of public secondary schools where 6 principals were selected through purposive sampling from the top three and bottom three performing schools. Ten form three and form four students were also randomly selected from the top three and bottom three performing schools to obtain a sample size of 120 students. Data was collected using a structured questionnaire. Data collected was analyzed using descriptive and inferential statistics with the help of the statistical package for social scientists, version 26.0. A multiple Linear Regression model was used to model the relationship between the independent variable and the response variable (academic performance). The study concludes that mentorship programs have a significant positive effect on academic performance, as indicated by their p-values (P<0.05). The study recommends that schools should ensure that there are functional mentoring programs in schools, as they have been shown to positively influence academic performance. Such programs may provide guidance, support and career direction.
