Manage => Manage teachers => Manually add a teacher (type their First name, Last name and Email) => +Add a new teacher.
The new teacher will receive an Activation email. Ask them to always check their spam/junk email folder in case the email goes there. This email has a link they need to click which takes them to a page to fill in their details and get logged into the site.
You can also upload a CSV file using our CSV template if you have to upload many teachers at once.
Teachers will need to link themselves to their teaching groups. See the article linked at the bottom of this page to find out how.
