Paul, Good question. Those that take all day to do an inspection and report would have to have better than 16 years in the business. Maybe ASHI's 250 X 3 could be a realistic minimum. That way anyone doing 1 a day would have the needed 750 inspections in a couple of years. Perhaps a sliding scale, like 5000/2 hour inspections, or 2500/4 hour inspections, or 833/6 hour inspections, or 625/8 hour inspections. Perhaps a report based number could work, based on check list vs. a written report. Check list need 5000, written need 50. Since most state licensing is only intended to demonstration a minimum of competence and not guru-hood, 250 might be sufficient. That number seems to be quite difficult for many newbies at ASHI, I think that that number has worked well for them. What have the other states with licensing done? George
