You can have different roles at different schools!  You can be both a PARENT at one school because your child attends that school, and using that same account, you can also be a TEACHER at the school you work at.

It is CRITICAL that if you have a child that attends a different school, that you set your ROLES properly, other you will show up as a teacher at the school your child attends due to your teacher role at your school and this causes problems.
