The WaterZeker home course
Alongside our work for schools and pools, we offer an online home course that helps parents work on water safety at home — built on the same knowledge and learning path. The course is offered through the Dutch Foundation for Water & Swimming Safety (NSWZ).
Quality
A certificate that reflects what a child can actually do
Our certification lines, assessment frameworks and quality standards are clear and verifiable. Quality is kept separate from commercial interest: an assessment is never for sale.
