In my save at the start of FoV I learned unarmed expertise up to level 13 from my battle tower trainer, and then checked the two trainers in the ministry, each of which had 2 of the other expertise skills (up to 13).
With a new FoV character, I checked the ministry trainers first, and they still only had these skills up to level 13 (the male trainer had one handed expertise and sword and shield, while the female trainer had unarmed, duel wield and two handed), and the same with Kenneth in the battle tower. Maybe the level 15 upgrade needs to be unlocked somehow for either a new or existing character?
Maybe they do, but if so, I didn't notice a way to unlock them during the story. They must've just appeared.
