A systematic review of 200 studies concluded the evidence base on CLTS effectiveness is still weak, with little monitoring or evaluation of impacts despite large international funders backing the approach. A 2013 study of 116 African villages declared open defecation free after CLTS found that, using broader criteria, an overall slippage rate of 92 percent had occurred, and a 2018 study found little evidence for sustained sanitation behavior change as a result of CLTS.
What would resolve this Long-term, controlled follow-up studies tracking latrine use, sustained open-defecation-free status and health outcomes several years after a community's CLTS trigger event, rather than short-term post-triggering counts alone.
