I am a relative "newbie", that feels that there are other paths than the one expressed above. My history goes like this: I have had a degree in Electronic Engineering for 30 years. Designed, drafted, engineered and built 2200 sq ft 3 level cabin in the mountains, with full compliance to the State Building codes and requirements. I learned a lot there, but certainly not enough to call myself an inspector. Other than that, no experience in construction or codes. (by the way, the instructors on several occasions told me that being an engineer would get in the way of being a home inspector. I think that is a poor generalization.) I found the 2 week ITA on-site course to be a great introductory course for learning the basics of what a Home Inspector needs to know. Does it instantly make you a good inspector? NO. But it does give a rounded perspective of what a house is, how the systems work, the interaction of these systems, how things have changed over time, and even more important, how much you do NOT know. I found it invaluable, and worth the time and money spent. In fact, I believe that ALL inspectors should go through a multi-week on-site structured course before entering the profession. (I find it difficult to believe that correspondence courses can come close to depth of an on-site class.) I believe that those of you that take on a new candidate for inspection will find it much easier if they have this education behind them. The classes became the springboard to daily researching the web, libraries, and ........ materials to study. Websites like Journal of Light Construction, Building Science......, the Mfgrs. sites, etc. I read daily the forum boards like this one, ASHI, The Inspectors Journal, and others........ I am just beginning to comment on and post replys on existing posts. I do think one shortcoming of the class I took is in not supplying a road map for continued learning in each of the disciplines. Like a list of "must" websites for further learning. The list seems to always be a list of the other course offerings. But, that is not a reason for discounting the value of these instruction companies. The next important (no, I mean critical) thing is knowing what you do not know. And, when you don't know, taking the time to learn. If you are too confident, then you will be a problem to yourself and the industry. I joined ASHI in October, passed the exams in November, began doing ride-alongs with a 14 year veteran in November, was doing parallel inspections all December through mid-Jan, and then began inspecting and writing my own reports in mid-Jan. I advanced to ASHI Assoc. with Logo several months ago, and am close to 100 fee paid inspections. AND, I am a GOOD and an ETHICAL inspector. My MUST list for an inspector in training: 1. Attendance at a reputable 2-week on-site class. 2. Immediately preparing for and taking the NHIE exams. There is no better time to do them than in the weeks following the classes. I do not feel that a new inspector should be doing inspections until these exams are passed. 3. Find an inspector to be a mentor 4. If there is a local HI chapter, join it. (no matter what national organization it is.) 5. A commitment to lifetime learning, not limited to just "conferences".
