This study aimed to identify the professional competency training needs of agricultural extension agents in Kenya given changing trends in agriculture. A survey of 440 extension agents found the highest training needs were in management skills, communication and information technology, instructional skills, and cross-cutting issues. Training needs varied between public and private extension agents as well as between frontline workers and subject matter specialists. The study recommends integrating competency training in undergraduate education and in-service training programs to better equip agents for agricultural extension work.
