I read through this document to get a good understanding of the legislative changes around the VCA. I also attended a Board training in October 2016. The training provided a great Self-Assessment Tool for Schools.
Of note the training highlighted how the Board decide on the level of checks they wish to undertake. For example, Board members do not need checking however most schools would expect this to be done.
For example, Schools can ask all parents if they would like to volunteer as parent help throughout the year and explain that they must have a police vet in order to guarantee student safety.
