A join code lets students add themselves to your classroom, which is usually the quickest way to get a whole class in at once.
There are four ways to add students. Two of them import from Google, which your IT administrator sets up; the other two are below.
1. Open your classroom from the sidebar and go to the Students tab.
2. Click Add students.
3. Choose Share a join code, then click Next.
4. You get a six-character join code and a join link. Give students either one.
What the student does
A student with the link just follows it. A student with the code signs in, then enters the code to join the class. Either way they appear in your Students tab once they have joined.
The code belongs to the classroom, so you can reuse it for the whole class rather than inviting people one at a time.
