This situation has not been helped by the training industry itself, with outlandish claims designed to attract clients. For example, an advertisement in a recent national computing magazine proclaimed boldly, "Learn to Repair and Upgrade Personal Computers – Plus full theory of operation". No prerequisites are required and all it takes is thirteen hours of tuition over four weeks. The learning of this complex practical skill is also available by correspondence, with the student being awarded an accredited certificate on passing one assignment!
