In many developing countries, girls lack the knowledge, support and resources (facilities and sanitary materials) to manage their menstruation with confidence and without shame. In Fiji, there is a lack of information regarding menstrual hygiene management (MHM). In order to gain a better understanding of the situation for girls, UNICEF partnered with the Fiji Ministry of Education, Heritage and Arts (MoEHA), Emory University, the Fijian Teachers Association (FTA) and Project HEAVEN (PH) to carry out formative research assessing the menstruation-related challenges girls in Fiji face at school. This report summarizes those challenges, their causes, and the impact they have on girls’ education and social behaviours. The assessment aims to provide a better understanding of girls’ menstruation experiences and identify barriers to effective MHM at school. The research provides useful evidence, to address these barriers to MHM in the rebuilding of school toilets damaged by Cyclone Winston in February 2016.
