The Washington Post’s education columnist Jay Mathews has been ranking the most challenging schools in the country and the D.C. region for 16 years. There are more than 1,900 schools on the America’s Most Challenging High Schools 2014 list. Noted in the national and local tables is the percentage of students eligible for government meal subsidies — a common benchmark for poverty — and each school’s average SAT score.Rider High School ranked 117 out of 162 Texas High Schools selected, and 1222 out of 2039 selected nationally (as of 4/9/14).The top three national schools include American Indian Public Charter in Oakland, CA; Uplift Education North Hills Preparatory in Irving, TX; and Corbett Charter in Corbett, OR. The top DC area schools include: Saint Anselm's Abbey (P), Washington International School (P), and H-B Woodlawn.The new question added to the survey this year reflecting a change in school cultures was whether each school has an 11-person football team. Jay Mathews writes that research indicates that high school sports, including football, give students valuable time-management and leadership skills.View the Post’s full list of national and local rankings of how effectively a school prepares its students for college here: http://apps.washingtonpost.com/local/highschoolchallenge/.
