Here are a couple of companies that we have used for auditor training at our company. A2LA is our accrediting body to Guide 25 and their website is
www.a2la.org. We have attended several of their classes. Also used Excel Corp. for RAB Lead Auditor Training, and their website is
www.excelpartners.com. Our experience is that both companies have excellent programs, and are great to work with. Both will come on-site or have classes scheduled throughout the US during the year. The two new brochures I have show classes in Chicago & Long Island for Excel and Minneapolis for A2LA. Excel is located in Sandy Hook, CT. and A2LA is located in Frederick MD. If you need any other info, e-mail me. Good Luck!
