I am trying to access School Spring. I was able to do so earlier in the year when I applied for a job. I could not not get in and asked to reset my password but never got an email to reset it. So, I registered for Power School, bit I still cannot get in.
Please refer to this article: Login-Issues-on-the-new-SchoolSpring to troubleshoot further.
If this does not work try doing the following. When you signup use the same information from your old account but make sure to click sign up not sign in. School spring should include this information and the information listed above on the login page.
If this does not work, I suggest submitting a service request in the following link.
