Parenting suitability
Parenting is one job where the applicant doesn't need a qualification. Setting people down to do a test in order to keep their kids would be too radical an idea and probably wouldn't work. The State has had a lamentable record as a substitute for parents and the kids would probably end up being abused in State Care. A team approach, where a social worker would keep an eye on things and intervene only when things get out of hand is needed, the trouble is that things often escalate into murder or serious injury very quickly before anything unusual ( neglect, bad influence etc... ) is detected.
