Why is the start date on consent forms different than the start date on the approval letter?
The dates on the approval letter follow the date of the IRB Meeting when the initial was presented and approved (even if there were contingencies to be met): they are the start and ending dates of the first full year approval period. When the first date is different on the consent form(s), the first date indicates the date that any contingencies were removed, and the second date will be the same as on the approval letter, i.e., the end of the approval term.
