Other than a few guilds, such as the arcanists and alchemists and such, education is hardly held in high regard or seen as important to the average Eorzean. Most are completely illiterate and could barely spell out their given name. And while adventurers such as ourselves seem somewhat educated, it could also be constructed that we simply say very little and act as a third party for almost all our interactions, so it's showing neither an educated individual nor uneducated.

I can't see anyone going to school any time soon.
