The update that PowerSchool released for hosting customers over the weekend has caused an issue where prior Discipline Tracking entries no longer show up on the page. Rest assured, the data is still there. One school district has already filed a support case about it, and I’ve communicated details, along with a fix, to PowerSchool’s Alaska state reporting manager.
If you need the functionality restored to normal faster than PowerSchool can get an update released, let me know and I can help you with a custom page that will restore functionality. (Though that does mean removing the custom page once PowerSchool releases an update.)
