Hi silverysea. I do a lot of GCSE tuition for students all across my local area and some come from quite a way away. I have never really been 'interviewed' by parents but I do have a detailed document which I send to interested parties which outlines my academic background, teaching credentials and teaching experience. Info like this should be readily available from any potential tutors. A key factor should be how far the tutor is au fait with current syllabus requirements and the different boards as well - for example, I teach the AQA, EDEXCEL and also the EDEXCEL iGCSE versions of my subject (barely any schools follow OCR but I am still au fait with it)- knowledge like this is critical. They should also fully understand the assessment objectives and how the subjects are marked too - have they had any experience marking for the exam boards? I have marked for two. This stuff helps IMO. Also, have they taught the subject in a school, successfully? that would be the dealbreaker for me. If I was sending my dd to a tutor I would want someone with good practical experience of delivering that subject in a classroom.
I think there are lots of very good people out there but equally I am often a bit
at how unqualified and inexperienced people take up tutoring because they think it's easy money.
