Average Years of Relevant Experience of Office Leader

How many years of relevant work experience should the leader of an IR/IE office have? From the 2018 AIR National Survey of IR Offices, we learned that the average office leader has spent 18 years working in higher education, 11 years working in the IR/IE field, 10 years working at the current institution, and 6 years leading the IR/IE unit at their current institution. From these data, we can see that the average office leader worked in a field outside of IR/IE for 7 years before transitioning to the IR/IE field.
