Water, sanitation and hygiene (WASH) in schools in Vanuatu has the opportunity to improve children’s health, increase attendance and performance at school and address gender and social inequalities. The WASH in Schools - Call to Action workshop presented a snapshot of WASH in Schools in Vanuatu, investigated the road to improvement and was the first step in engaging relevant stakeholders through a Call to Action. The snapshot of the current situation of WASH in Schools was analysed through problem trees and bottleneck analysis, drawing out the root causes and major bottlenecks in the enabling environment, supply, demand and quality of WASH in Schools in Vanuatu. The final recommendations targeted four areas for improvement including coordination, monitoring, scaling-up at the school level and advocacy.
