In the event that a Parent has two Students with SCOIR accounts and is already set up with one Student, the second Student can still invite the Parent to SCOIR and the Parent will have access to both Students.
The email for the second Student will not require a password, but will simply ask if you accept the new Student. It will look like this:
It will then re-direct to the SCOIR login screen. Your new Student will appear next to your existing Student to accept.
Once you access SCOIR, the upper left side will allow switching between Students for each individual College selections.
