Step 2: Click on the pink add code to which you want to add students:
Step 3: A new window will appear. Copy the URL and send that link to the students for that roster.
Step 4: When students click that link they will go to this page and click "Next"
Step 5: Have students click "My School Uses Google". They'll then walk through the on-screen instructions to sign in with Google.
And you're done! In the future, when students login to InnerOrbit (either with innerorbit.com/login or using your assessment link) they'll click "login with Google".
