Hi Chrisy. We run instructor courses under the accreditation of ITSSAR & RTITB from our centre in Bristol but there are many other centres closer to Scotland. The instructor course is of 10 days duration. The RTITB course results are determined by a final day examination, the ITSSAR course results are decided by constant assessment of the course Tutor based on nine elements. As for potential earnings ? That depends on the work you bring in or the company you work for - that can be anything from £80 - 160 per day. Hope this helps. Drop me a line at [email address removed] If you think I can help out further.
