- Refunds: you may request a refund within 7 days of enrolment if you have consumed less than 20% of the course — measured by lessons marked complete and files downloaded. After that, or once downloadable course files have been taken, the purchase is final. This does not affect rights you have under mandatory consumer law. See the Refund & Cancellation Policy and Course Access Policy.
- A “Certificate of Completion” is issued at the end. It is a record of finishing this course — it is not an accredited qualification.
About the certificate
Learners who complete every lesson receive a Certificate of Completion. It records that the course was finished. Watershed Learning is not an accredited institution and does not award credit, grades or qualifications.
Common questions
How much adult help is needed?
Most learners aged ten and up work independently between investigations. Younger learners will want an adult alongside for setup.
Is there a matching kit?
Yes — the Build-a-Water-Filter STEM Kit covers module five, or take the course and kit together in the Young Water Scientist Bundle.
