This book discusses factors that influence enrolment levels in secondary schools in Keiyo District, Kenya. The author argues that with the introduction of free primary and secondary education in Kenya, it was expected that the country would experience an increase in secondary school enrolment coupled with a corresponding expansion of secondary schools. However, the author observes, this has not been the case in Keiyo District. Basing her arguments on Max Weber’s Theory of Production Function, Bargerei takes the reader through how various factors such as geographical location, attitude of the community towards a school, academic performance, head teachers’ leadership and government policies impinge on enrolment levels. The author posits that once these factors are taken into consideration, the wide disparity in enrolment levels between schools in areas perceived to be in harsh conditions and those in urban areas will be addressed. The discussions in this text are a step-by-step guide on how schools can come up with mechanisms to enhance their optimal enrolment levels. This book is highly recommended to stakeholders in the Education Sector in Kenya and beyond.
