This paper sought to determine economic factors that influence access to secondary educational opportunities in Narok County, Kenya and to suggest strategies to help raise the transition rates of learners from primary to secondary schools. The study employed descriptive survey research design involving both qualitative and quantitative approaches. Study participants comprised head teachers, teachers and students in both primary and secondary schools. Stratified sampling technique was used to select twenty-four (24) primary school head teachers, forty-eight (48) primary school teachers and eight (8) secondary school principals. A total of 68 class eight pupils and 44 form one students were selected using simple random sampling from the sampled schools. Data were collected using questionnaires and an interview schedule. Pilot testing was done with questionnaires to test reliability and validity. To obtain the reliability the test-retest method was employed. Pearson Product Moment was employed to compute the correlation coefficient. A correlation co-efficient of 0.77 was obtained. Qualitative data were analysed inductively through content analysis while SPSS was used to analyse quantitative data. Results were presented in form of tables, figures, frequencies and percentages. It was established that household poverty and opportunity costs of education have influences on completion rates and lead to dropouts from basic schooling. The study recommends the need for the government and private sector employing a long term strategy in expanding secondary education in Kenya. This could include poverty mitigation and reduction in cost of secondary schooling and improvement of basic infrastructure, improvement of the quality of education in the country in order to reduce the opportunity costs and also through provision of more subsidies to improve the level of enrollment in basic education
