I always think of Students as being like Peasants. They do simple stuff until they get enough ranks in a real profession to get a better title.
I make my peasants into soldiers, so here newcomer *hands dubradditz a wooden sword* go and kill those unicorns over there.
And for a second I thought that I was the only one who got rid of my peasents that way.
Get RID of them? I recruit them, train them, and send them to swamp goblins.
Or they go into the cleanup force, picking up things the goblins drop and tossing them in a hole, and stacking the bodies up to rot.
And then sorting through this mysterious pile of goblin equipment.
Or gain an actual skill by way of natural selection; if they consistently get to the smelter, furnace, or construction project first, they gain a title, get promoted and taken off constant hauling.
Or in the case of one poor female dwarf, stuck into a small room adjacent to the bone stockpile and told to make bone bolts on repeat, no matter whether the workshop's empty or she's up to her ears in crossbow bolts.
