McLean, Langley Rank High in Washington Post High School Challenge

McLean and Langley High Schools placed in the top 20 in Washington Post education reporter Jay Mathews' annual Challenge Index. 

McLean ranks 14th and Langley ranks 16th in the annual rankings of 50 high schools in the Washington Metro area.

The highest-ranking Fairfax County high school is Oakton High School, which is ranked No. 10.

The index score is the number of college-level tests given at a school in 2011 divided by the number of graduates that year.

Also noted are the percentage of students who come from families that qualify for free and reduced lunch (Subs. lunch), an indicator of poverty, and the percentage of graduates who passed at least one college-level test during their high school career, called equity and excellence, (E&E). More than 170 public and private schools are on the list.
