You won't find this kind of ranking. Consulting is not an academic discipline. It is an industry. I don't know of a single school that offers a concentration in consulting. The closest you'll see is a strategy concentration/major. It's better for you to look at the employment reports for the schools you're interested in. You'll be able to see the percentage of students who go into the consulting/strategy function and which companies recruit heavily at the school. You'll have to make your own personal rankings based on those stats.
