How to check it yourself

Open the IRHACE register →What a TCH badge adds
When a member claims this, someone at TCH checks it against the source and stamps the date. The badge shows that date and expires after 12 months, so it stops claiming anything once it ages out. Anything a business has only told us stays marked self-declared.
