There is a HUGE difference between a family that is choosing to home educate their child, and a family choosing to not send a child to school in order to become invisible. These children are absolutely not being home educated!
Home educated children are seen by doctors, dentists, other parents, are part of home ed groups. It's a lot of effort on a parent's part to home educate a child. My children are seen in my community every day - shops, cafes, parks, group sessions, sports clubs, local charities etc.
Children that are kept out of school for radicalisation or neglectful reasons are most certainly NOT home educated.
A DBS won't help any of this. What is it being suggested red flags are for DBS checked parents? This worries me.
I have been home educating for seven years now. I have also never been visited by anyone officially. Despite asking for this at the start. We get no help in my area. No resources or support at all apart from within the home Ed community, which is immensely supportive, luckily.
