As a centre, we have a policy in place that in the event a child is more than one hour late, we can mark the child absent (if there was no communication from the parent that they will be late) However, we have noticed that after we have marked a child absent, and a parent then arrives, they do not see that we marked the child absent and can therefore override the system. Is there something we can put in place that should the parent arrive after being marked absent, they see some sort of an alert on the sign in iPad and therefore have to talk to us first as we do not always catch parents when they are in and out of the centre at the speed of lightning:)
