For what it is worth, my experience with the Ministry of Education here is that if I am telling them to do something that isn't more or less what they already want to do, I need rhetorical leverage. At best, I have obtained this (i.e., managed to get their attention and motivate them) by a combination of getting an article in the newspaper (+ a couple of radio spots) and going over their heads to the political level of the Ministry (i.e., managing to talk to someone who had the Minister's ear). This strategy requires the ability to write a press release (one which takes into account what motivates journalists) and find a political connection.
