The Washington Post 2011 Challenge Index, released Sunday, ranks Woodrow Wilson High School No. 588 among the nation’s best 1,900 high schools.

Woodrow is ranked No. 64 among Texas high schools, just above Coppell and Hillcrest high schools. The only DISD non-magnet school to rank higher than Woodrow is W.T. White, which ranks No. 34 in Texas.

Here’s how the Post formulates its rankings:

The formula is simple: Divide the number of Advanced Placement, International Baccalaureate or other college-level tests a school gave in 2010 by the number of graduating seniors. While not a measure of the overall quality of the school, the rating can reveal the level of a high school’s commitment to preparing average students for college.

For the fifth consecutive year, high schools at the Yvonne A. Ewell Townview Center took the top two spots in the index. The Science and Engineering Magnet at Townview is the No. 1 high school in the nation, according to the index. The TAG magnet at Townview is ranked second in the nation.
