Where do Robinson, Lake Braddock and West Springfield Rank?

All three Burke-area high schools gained high spots on the annual Washington Post ranking of Virginia schools.

Lake Braddock Secondary School was ranked highest, at number 9, with West Springfield High School coming in at 19 and Robinson Secondary School at 23. These rankings are out of 102 Virginia schools on the list.

Since 1998, Washington Post education reporter Jay Mathews has ranked Washington-area public high schools using the Challenge Index, his measure of how effectively a school prepares its students for college.

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