The Appraiser skill relates to trading and item value estimation. Your fortress's representative trader gains appraiser skill the first time the trading screen is opened for each caravan visit, but the item valuations in the Trade Depot are determined by your broker's appraiser skill, not your fortress representative's. (You can, however, reassign the position of broker to your fortress representative to display item values at the depot.) Appraiser has no associated assignable labors. A good way to train another dwarf is to assign him as broker, make him go to the trade depot and (T)rade, exit and assign the "main" broker again and make him do the actual trading.
In order to have access to the monetary fortress value estimates in the status menu, as well as individual item values, a dwarf with the Appraiser skill must be appointed as broker in the nobles screen. (Note that this is not necessary for the display of item quality - the indicators near the item names - which will always appear.)-
Sometimes, migrants who arrive with Appraiser as their highest skill are counted as "Friendly" units rather than as part of the fortress population.Bug:5098 They linger at the edge of the map instead of gathering at a meeting hall, and so may delay a number of migrants from entering the map until they either get killed by something or decide to move aside. Ordering soldiers to kill them will result in a loyalty cascade.
