What we are learning

Insights from the School-WISE project

Data collection is complete at several sites and analysis is underway. Full findings will be published in peer-reviewed papers and in site reports returned to participating schools. Three patterns are already clear.

Pattern one

Service availability is not the same as service adequacy

Students and staff at schools classified as having basic WASH services can still go without.

Qualitative work established this; the School-WISE data now show it quantitatively, revealing how often these problems occur and who is most affected. At several sites where WASH infrastructure was available, students and staff still reported substantial difficulty reaching the facilities, or found that the services were not of adequate quality and functionality to meet their needs reliably.

The practical consequence is that supply-side indicators alone can make a school look adequately served while the people inside it are not. Experiential data complement those indicators: they bring these difficulties into view and support the work of making sure people's WASH needs are met.

Pattern two

WASH disparities exist within and across schools

Because the scales collect individual-level data rather than a single facility rating, they can show disparities by age, gender, disability, and position at the school.

This makes it possible to identify disparities across groups and to reveal where there is a mismatch between the WASH services a school has and what people experience when they try to use them.

Across several sites, for example, we see differences between students and staff, although not always in the same direction. Sometimes staff have access to better services; sometimes they hold higher expectations of those services and are more likely to report problems that affect their wellbeing and their ability to do their work.

Pattern three

Challenges across all domains

Difficulties are not confined to one domain.

Across sites, students and staff report problems with water, sanitation, hygiene, and waste management, and which domain is most burdensome differs from school to school. Handwashing infrastructure, for example, is often present; soap at the moment of need often is not.

Among the most common challenges across schools is managing menstruation, which is not currently captured as a standalone service level in global monitoring. Asking students and staff who menstruate about their own experience is among the best ways to identify where provision falls short.

How to read this. Each dot is the share of respondents who said they had experienced the item (answering “sometimes” or “many times” rather than “never”), out of those who answered it. The grey bar shows the gap between students and school staff.

Item wording was adapted for each site and is shortened here; hover over a dot for the percentage and the number of respondents behind it. Menstrual health items were asked only of students and staff who menstruate. Values based on fewer than 30 respondents are not shown.

Students answered about the past week and school staff about the past four weeks.

How to read this. Each dot is the share of respondents who said they had experienced the item (answering “sometimes” or “many times” rather than “never”), out of those who answered it. The grey bar shows the gap between students and school staff.

Item wording was adapted for each site and is shortened here; hover over a dot for the percentage and the number of respondents behind it. Menstrual health items were asked only of students and staff who menstruate. Values based on fewer than 30 respondents are not shown.

Students answered about the past week and school staff about the past four weeks.

These are preliminary descriptive results from the scale-development phase. They describe the participating schools only, are not representative of the country, and have not yet been peer reviewed.

More analyses ahead

The core purpose of this project is to determine which items work well for assessing WASH insecurity within and across settings. Analyses are currently focused on which items are understood consistently across languages and settings, which items distinguish schools that differ in ways we can verify, and which items can be dropped without losing information. The final scale will be shorter than the instruments now being implemented.

Findings will be published in peer-reviewed papers and returned to participating schools and ministries as short reports. The site explorer above is a first, preliminary version of the interactive site profiles; it will be updated as more findings emerge.
