This report covers the main findings of the impact evaluation conducted of a communityled total sanitation (CLTS) campaign implemented by the government of Mali (Direction Nationale de l’Assainissement) with the support of UNICEF. We conducted a clusterrandomized controlled trial among 121 villages randomly selected from the district of Koulikoro in order to evaluate health and non-health program impacts. Baseline data was collected during April-June 2011, the CLTS intervention program was implemented between September-June 2012, and follow-up data was collected in April-June 2013. A total of 4532 households were enrolled at baseline and 4299 were visited at follow up; 89% of baseline households (N=4031) were successfully matched to a household at follow up. The primary outcomes presented in this report are reported for those households present at both baseline and follow up.
