More than 120 schools around the country were set on fire last year, according to research by a Canadian professor. Almost none of the cases have been successfully prosecuted.
Kenya is East Africa's largest economy but unemployment is high and corruption is rife, making life difficult for many ordinary people.
Control of a school can mean not just a government salary but an opportunity to extort extra money from students and parents in fees or other charges.
Many of the fires are set by students in protest at harsh discipline, poor teaching and corruption, according to Canadian Elizabeth Cooper, assistant professor of International Studies at Simon Fraser University.
