(WXIA) -- The Washington Post has unveiled its 2014 list of America's Most Challenging High Schools.
The newspaper determines the annual rankings through a ratio: the number of Advanced Placement, International Baccalaureate and Advanced International Certificate of Education tests a school gives each year, divided by the number of graduating seniors.
Ten Fulton County schools made the list, which features more than 2,000 high schools across the country. The listed numbers are each school's national ranking.
215. Alpharetta HS
232. Riverwood International Charter School
244. Northview HS
263. Milton HS
265. Chattahoochee HS
380. Roswell HS
