From the My School option, select School Settings, this will open the basic settings of the Organization. Once there, scroll down and click the option that says Add students to school

A pop up will appear with two options, Manual creation, and import from Excel. The Excel option is on the left.

Either download the template on the page, or create your own CSV file with the appropriate emails, usernames, and passwords for your students. Make sure to include a header row like in the example, and to include all three of these pieces of information for each user. Passwords must be at least 8 characters. 

After uploading the CSV, ThingLink will create accounts for your students that reflect the included information. They can log in with that information and do not need to register. On the first day of class, they should use their teacher's group code to join their group.
