A one-page scoring sheet for checking whether a hygiene promotion message or poster, leaflet or other awareness material is good enough before you test it with volunteers or community members.
Each message is scored from 1 to 3 against five criteria: is it simple, does it state a benefit, does it tell people what to do, does it suit the audience and their culture and language, and does it suit the channel it will be sent through. A message scoring below 11 out of 15 should be revised before going any further.
