You can invite students to enroll in your class in 3 ways:

• Send an invite link—Students click the link to join.
  This feature is rolling out over the next week. 
• Send an email invite—Students can join from the email or in Classroom. 
• Share a class code—Students enter the code in Classroom.

If students have trouble with the link or code, you can reset them, or send students an email invite instead.

For instructions to join a class, students can go to Join a class as a student.

Note: Students can unenroll themselves from classes. If they unenroll, their grades are removed.

Manage your invite link or class code

For each class, you have an invite link and a class code, known as the Invite codes. You can share the invite codes with students, so they can join the class.

By default, the invite codes are on (enabled).

You can:

• Reset invite codes, if you have trouble with them.
• Disable invite codes, so new students can't join your class.

  You only need to do this if you disabled the codes.

When you reset or enable invite codes, Classroom creates new invite codes. The previous codes won't work.
