I was wondering if anyone could tell me how they informed the staff of the changes of Disqualification by Association and what people have put in their self-declaration form instead?

We run a holiday day camps where children are from reception age and we are a school from 3-19. I have read up on the subject but I am finding the advice a bit conflicted as to whether the DBS on it's own is appropriate enough.

We have been in the process of getting a self-declaration form approved but this was done a while ago and wasn't taking into account the changes of Disqualification. Also, are there any schools out there that just do yearly self-declaration forms rather than renewing DBS every 3 years? If so what are we allowed/not allowed to ask anymore?!
