There are many methodologies for ranking and comparing MBA programs. Business school rankings are a good place to start when researching your options, but be careful - they are subjective and far from perfect. Sometimes you will find large differences in the rankings, so it is always best to look beyond them as well.
Another item to consider is the growing number of online MBA programs. There are many flexible and specialized programs that could also be useful as you are considering the many MBA programs offered around the world.
