Assessment of sanitation facilities is based on three criteria: quantity, quality and usage. Only by considering all three will you be able to accurately assess the current situation.

====Assessment criteria====
As with the assessment of sanitation facilities, assessment of a school’s water supply is also based on three criteria, this time: quantity, quality and convenience. Again, only by considering all three will you be able to assess the current situation accurately.

====Assessment criteria====
An assessment of children’s knowledge and practice of handwashing with soap is an indicator of the overall standard of hygiene in the school, but it may not reflect the overall standard of health as problems may be caused by inadequate sanitation facilities or a lack of a safe water supply. The results of an assessment of handwashing therefore, will normally need to be considered alongside the sanitation and water supply assessments.
