Single Sign In for Parents in Power School. The first thing you need to do is click on Create Account. Create your own username and password. To add your child/children you will put in their first name only. Enter the user Web ID (ACCESS ID) and Web password (Access Pasword) assigned to you by Power School (this is case sensitive). Then choose the relationship. When you have all of your children entered click Enter. Once this is created you should only have to log in once to access each of your children's grades. If your kids are in grade school or high school you will only have to log in the one time to access them. Once you log in you then go to the email and select what you want emailed to you and add another email address. This does not carry over from how it was previously set up. You can always go to the preferences if you need to add another child.
