<p>FYI, there is no such thing as official rankings for any program in any field that I am aware of. They are all third party rankings by publications that have copy to sell and shareholders to please. Take them for what they are, a guide, but not an end all.</p>
<p>BTW, US News methodologies for any grad program are almost always just peer review surveys: "All the health rankings are based solely on the results of peer assessment surveys sent to deans, other administrators, and/or faculty at accredited degree programs or schools in each discipline. " Take that for what it is worth. Never make a decision solely based on rankings.</p>
