Staff members that work across schools using the same contact details can only view one school they are connected to on School Gateway.
In order for them to access multiple schools as a staff member on School Gateway, the schools would need to import different contact email addresses to enable the staff member to register for separate School Gateway accounts.
Please note
Although they can only see one school that they are linked to as a staff member on the one School Gateway account, they are still able to see other schools that they are linked to as a parent on the same School Gateway account.
