Lori - Thanks for sharing your experience of having an internal audit directly help in identifying areas which could be addressed prior to an external accreditation visit. This demonstrates a great positive outcome and I am impressed that you are now implementing an annual review at each campus. At one company I worked for, audit teams included members of the internal audit department plus we implemented a "guest auditor" program whereby we invited campus based employees (usually no more than one for any given audit) to be part of the team. We would train them on how to conduct some of the testing. It was mutually beneficial as the guest auditors gained insight on what to look out for at their own campus and they in turn helped the internal audit members see different angles and approaches which sometimes prompted us to modify our testing to catch additional areas of risk.
