This question: Is there a quantitative finance ranking system for universities? was closed as an off-topic. While reading articles What kind of questions can I ask here? and What kind of questions should I not ask here? I haven't find a reason for my question to be closed.
To clarify the situation: that is not the question about your favorite quant school. That is just a call for the reference what are the top schools in quantitative/mathematical finance. I am sure that there should be lists/ratings like there are for mathematical universities - I've just haven't found them on the web.
Finally, this question is not to build up the discussion. It asks for the direct, well-stated answer. It is related to the academic area of the quant-field. I ask it on exactly this site because here one can hope to receive a nice answer which will be non-subjective and useful rather than what I expect to receive on other sites.
