(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.
Carrollton High School is No. 1644 on the list, which features more than 2,000 high schools across the country.
