Portal Administrators are able to give other teachers at their schools access through the Portal Administration page. Clicking on the "Portal Administration" link will bring you to a page with 20 blank slots. It should look like a larger version of what is below.

Enter an e-mail address for each teacher you want to have access and click the "Save Changes" button. It is important that you enter in the correct e-mail address. E-mail will automatically be sent to them informing them that they have been given access to the Mission: Solar System, K-3 Space, and Orbital Laboratory packages. Attached to this e-mail will be a link and instructions on how they can register as well. Their process will be almost identical to the one you went through. The only change will be the fact that they will not be required to provide an authorization code, even if you did.

From the Portal Administration page, you will be able to check on the status of your teachers. The next time you visit this page, the teachers that you have previously entered will have either Registered or Pending written in the Registration Status column. This column will let you know which teachers have completed the registration process and which have yet to do so. If for some reason it becomes necessary to remove a teacher's access, all you have to do is delete his or her e-mail from this list before clicking on "Save changes."
