Below is a list of water, sanitation & hygiene (WASH) organizations with independent evaluations (out of nearly 1300 WASH organizations around the world that we have identified to date). We understand this list is not complete or comprehensive. Rather it is a list of evaluations (some of which might not be fully independent) that we assembled using the tools that a regular donor would have, such as web searches or word of mouth. We hope you can learn from them!
Has your organization had an independent evaluation? Have you done an independent evaluation of a WASH program? Please send an email or include the link in the comments section below.
