I'd like to know myself. I had the impression that promotion in the ATA after a certain rank was dependent on you running a school and promoting a certain ratio of students yourself. Thus, a person who just wants to practice and improve themselves could not advance.
I see another reason for wanting to advance in rank but not run a school - if you don't have time to run your own school, instead choosing to spend your time helping various schools in your country (and other countries) improve. I know my Grandmaster prefers that path and it would have been a great shame if he'd been denied higher grades because he didn't have his own school.
