Government officials can have traits/followers that increase clamour for reform, in an absolute monarchy I keep a close eye on my Gov. officials and have never had much trouble with unrest. I would say you should not put more then 2 schools in a single region, and then only in a "capital," and you need at least one tavern for each. Also I wouldn't put any schools in a "small" region (ie. only one building slot in regional capital.)
