Hello there
I'm not sure that it is regulated, seems to be a bit of a grey area from what I can make out. I've been looking at what's on offer myself and there are lots of IHM courses out there. They seem to vary enormously from one day workshops with no study element or exam, to 20 week diploma courses that have both practical and written exams at the end and case study work to do, as well as other course work. I suppose that what you want to get out of the course determines the one you choose. If you want to be an insured practitioner you would probably want to think about the diploma course or a similar certificated course, so you get in depth knowledge and practice and as much experience as possible. If it's something you'd like to be able to practise for pleasure on friends and family you might make a different choice. I'm sorry you're feeling swizzed about your course. Did they not deliver what they promised, or were your expectations not met because the course objectives and its nature weren't made clear?
