When I used to work in engineering many moons ago, the biggest two companies I worked for required employees to create a one page professional bio that could be supplied to clients that asked for it (and it apparently got asked for a lot). I think the bio was a far better idea than a full resume for many reasons, not the least of which was that the only personal information that appeared on it was my name. I was never asked to provide a bio or a resume as a flight instructor, but I can understand why clients would request it - as Blackhawk mentioned above, "trust us, we're professionals" just doesn't cut it anymore. I did have several situations were a potential student sat down with me before deciding to train and essentially interviewed me, even while I was employed by a Part 141 school. Much more often than not, they turned out to be my most conscientious students. In my opinion they are just trying to get the best service for their money, which sounds smart to me.
