Are you employing staff who have come from Overseas (that includes the EU) and are they providing Overseas Police Checks? Ok so we know that anyone who works in a school is in a regulated activity needs to be vetted with an Enhanced DBS. But a DBS only covers that person for the time they have been in the UK, it doesn't show up any convictions that have been given in a foreign country. I have heard some organisations that won't ask for such checks if the person has been living in the UK for a set amount of time, however, what if that person was convicted of serious sexual offences prior to that date?
A bit of an elephant in the room question and I'm expecting some lively debate on this one!
