This booklet is the ninth in a series of publications that address key themes of UNESCO’s work in HIV and health education. It is one of several contributions to school-based health promotion that UNESCO has produced to complement our work in HIV and sexuality education. The booklet lays out the context and rationale for education sector involvement, the characteristics of good quality puberty education and menstrual hygiene management, as well as key issues for programme development, implementation and sustainability. This booklet is intended mainly for education sector policy-makers, planners and managers. We hope it will also be useful for school governing bodies, administrators, head teachers, teachers and other educators who are tackling some of the challenges to create healthy learning environments.
