You can find the online test(s) on your dashboard. Use the Entity Type filters on the top part of your dashboard and select Worker to narrow down your people requests. You should be able to see mandatory online induction/s, just select the Complete Training button beside the alert to start.

If you do not pass the online test(s) or do not attempt them you won’t be able to go and work on-site, so to have access to the site and begin your work, you must take the required test(s).
