Under the current OFSTED safeguarding children act parent helpers in schools and nurseries must only have the normal checks carried such as a CRB if they are a regular helper. Adhoc helpers can be excused from this process. Both are "supervised". Parent helpers stretch to step parents grandparents in fact anyone that wants to volunteer.
My argument is introducing a child to a stranger in a trusted environment like school means that to the child that person is no longer a stranger and therefore they become a trusted adult to the child in and out of school. Whilst in school they are supervised outside of school they may not be. How do we explain to our children you can't trust that adult out of school because they aren't supervised. In fact how would we know which parent helper has had the checks.
It is unfair we are put in this position. I know CRBs only show what someone has been convicted of but this piece of legislation is allowing the possibility of a convicted adult working with our children in our schools and nurseries.
I would like to call that we enforce the official child protection checks on ALL helpers adhoc or regular, supervised or unsupervised and commence this immediately this is after all why we have these checks and why we enforce them in all other circumstances.
