As noted at AF.mil, the US military academies (Air Force, Navy, Army, Coast Guard, and Merchant Marine) were ranked in the “top 100” Best Value Colleges by the Princeton Review/USA Today (again, see 2009).

The military academies, which combine both military and academic training, are government-funded and built around their missions.  As a result, they are no-cost, have low student/teacher ratios, and provide some of the best educational opportunities in the US.

As quoted in the Air Force article, The Princeton Review said

If you can make it through this four-year gauntlet, though, an Air Force diploma is an awesome credential. You will almost certainly leave here with a knack for leadership and a skill set that will impress your friends.

While “impressing your friends” is hardly a worthwhile credential, it is worth noting that the Review recognizes the value of a military academy diploma.  They are challenging to earn, and are earned in limited numbers, making them a commodity even in the civilian sector.  (Though the education is valuable, an Academy diploma does not necessarily have instrinsic value within the military.)
