This manual for trainers outlines the information and materials required to undertake training in line with the WASH FIT Guide, including background documents, the content of the recommended training modules and training evaluation approaches. The modular approach outlined enables trainers to decide on all topics that are most useful to support the delivery of targeted training at the local level. It also provides sample training schedules, evaluation forms and is linked to a full set of interactive, adult-learning focused, training slides.
