If you have parents who are changing one another's data, you may want to consider creating Retricted Portal Accounts. You can limit their access and view. The documentation will guide you and our Support can assist you if you have additional questions.
As we have implemented parent data confirmation, we have seen custodial parents starting to delete non-custodial parents from the contacts list. Until this point, we have left those parent in there but tied them to a red flag noting the restraining order, no contact order, or whatever. What are other districts doing to note these types of important flags for people who should not be permitted contact with particular children?
