Ew, I hope not.
Those are so many great jobs that I'd love to level up without having it being handed to me fully leveled with my class. Especially Scholar -> Summoner, I'd really hope not.
The game has Dragoons, but it seems to be more of a title. And it also is related to Ishgard I believe? It's in part of the Conjurer storytelling.

if it went like that, youd have to level scholar to get smn specialty, youd probably have to level scholar to 30, at which point leveling either smn or scholar would level both, and give you acess to both skills
