A qualification for photo editor?

This i wrote because I have several time proposing as photo editor because I really have interest in photo editing. They told me that a photo editor must have a background of designer, since that i have only engineering education background but I increasing my photo editing knowledge through reading and internet browsing looking for tutorials. Could that possibly the main reason (education background) why i am not elected or being chosen as the photo editor? Not because of talented and still growing skill?
