That depends on the government building present in Sparte, i think. Right now i´m playing Macs; there is lvl 2 ( Macedon Satrapie ) built in Sparta, and all my FM become "Superb Administrators" after they stay a full round within the town. I might add, i´m using Konnie´s EDCT text files, so maybe the unmodified EB is different ( don´t remember ).
