The Top of the Class 2008

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 2007 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 5 percent of public schools measured this way.

If you have questions about the list, please contact challenge@washpost.com. Note: Subs. Lunch % is the percentage of students receiving federally subsidized meals. E and E % stands for equity and excellence percentage: the portion of all graduating seniors at a school that had at least one passing grade on one AP or IB test. For more information on methodology, see our FAQ; please leave your comments on the list in the comments box below.
