This paper investigates UNICEF and Plan International's internal consistency regarding what extent they are implementing water, sanitation, and hygiene (WASH) projects with gender sensitivity. UNICEF and Plan International are under scrutiny due to their influence in humanitarianism and their stated dedication to eradicating gender disparities within WASH; are they accountable towards their objectives? This topic is of great importance due to the role water, sanitation and hygiene play in girls' development, safety, health, and equality. Clean water, hygiene, sanitation and practicing proper menstrual health management, along with education, prepare women for a healthy life where their period does not hinder them from attending school or participating in the community. The focus of the study is thus how accountable UNICEF and Plan International are in implementing these objectives since it is such a vital part of including women in development and promoting equality. The study uses an intensive multiple case study along with a theoretical framework and analytical tools. The findings suggest that Plan International is more successful in implementing gender-sensitive objectives in their WASH projects, but neither Plan International nor UNICEF displayed full internal consistency, meaning that the projects scrutinised still lack gender focus. This study highlights the need for gender to be permeated throughout the entire WASH operation and that accountability continues to be a pressing issue within humanitarian organisations.
