An expensive advertising site. The Finders Fee for my tutor was £25. The references are hardly a guide to their work ethic having been written by friends and only including the first name of the peron writing it. I am astonished why First Tutors think this is a acceptable indication of a person's reliability and suitability to work with children. There is no CRB guaranteed. They do check the person's right to work in the UK which is the least of my concerns. I thought I was paying for robust background checks - but it appears not. Should I need another tutor, next time I will ask the school and other parents who they use.
