The report at a first glance seems to be that something is happening that the EU hasn't regulated, so they don't like it. They also want to see what fiscal advantage they can gain from it (interestingly HMRC have just announced that private tutors are next in their sights).
I'm in Belgium - I am going to be reorganising language tutoring for ds in Dutch over half term until his GCSE next year as I am not convinced that he will get an A next year. His teacher is a very nice lady, but with only 4 in the class, I would be expecting better results than I am seeing so far. Lots of parents both in the UK and here use tutors in Year 10 and 11 as they realise the importance of the grades at GCSE for later life. To an extent, as a teacher, I tutor ds in exam technique, writing to answer the question, looking out for key words and phrases in the questions, and ensuring that the question on the paper is answered, not the one you would like to be there.
I have done a bit of tutoring out here, but for a friend's lass who was struggling with English essays, and it was gratis anyway. I have been asked to provide tutoring for the 11 and 13 plus, but I don't know enough to do it, and frankly, having to set up a business in Belgium isn't worth the hassle.
I used to 'tutor' whilst teaching, in that I ran after school classes on a Tuesday,as part of my extra curricular activities contribution which covered revision, exam technique, how to structure answers, and to go over bits of the syllabus that some had trouble with. These were not just open to my Year 11 classes, but to all the Year 11s. As I examine, some found it useful to know what I would be looking for as an examiner; and also that I had time to go through things with them at a slower pace than we went at in class. In some cases attending that session from after the autumn half term to just before the GCSEs paid off with the increase of one or two grades on top of their predictions, especially for the lower end students. I think the comment in the report that 'tutoring' detracts from teaching if you do both is crap and painting teachers as unprofessional.
In an ideal world, no-one would need tutoring, but they do. Had my Mum paid for a maths tutor to explain it all to me in simple terms, I might have passed my O level; instead I failed it twice and got a CSE and a CEE, (the latter being an O level equivalent, so yes, I am allowed to teach!).
