28 Minn. schools make Newsweek's list of top public high schools

Newsweek published their list of America's Top 1,500 Public High Schools and 28 Minnesota schools made the cut. (via)

Here is how the ranking is created:

Public schools are ranked according to a ratio devised by Jay Mathews: the number of Advanced Placement, Intl. Baccalaureate and/or Cambridge tests taken by all students at a school in 2008 divided by the number of graduating seniors. All of the schools on the list have an index of at least 1.000; they are in the top 6 percent of public schools measured this way.
Check out which Minnesota schools made the list. See the full list here.

Do you think the ranking is a fair assessment of the "top" public schools in the country? Can a school really be judged based on the percentage of students taking advanced tests.
