This book discusses a study done on the implementation of Christian Religious Education (CRE) curriculum in secondary schools in Murang’a South District, Central Province, Kenya. The motivation to delve into this study came from gaps in available literature on implementation of CRE curriculum in secondary schools in Kenya. Additionally, teachers' perceptions have been ignored in available literature despite their impact on curriculum implementation processes. The study established that although CRE teachers in secondary schools in Murang’a South District handled huge teaching workloads and lacked adequate teaching-learning resources, they held positive perceptions towards implementation of CRE curriculum. The authors recommended that challenges facing implementation of CRE curriculum should urgently be addressed. They also recommended that a similar study should be done covering students' perceptions which were excluded in this study.
