(FOX19) - Ten Tri-State high schools have made The Washington Post's list of "America's Most Challenging High Schools."
Here's how local schools are ranked:
Walnut Hills: 87th nationally, first in Ohio
Highlands: 138th nationally, first in Kentucky
Wyoming: 106th nationally, second in Ohio
Indian Hill: 157th nationally, third in Ohio
Beechwood: 206th nationally, third in Kentucky
Madeira, 481st nationally, 13th in Ohio
Mariemont, 508th nationally, 16th in Ohio
Turpin: 1,120th nationally, 24th in Ohio
Covington Latin: 1,340th nationally, 13th in Kentucky
Dixie Heights, 1,786th nationally, 14th in Kentucky
There were no Tri-State schools on the list from Indiana.
The Post says schools are ranked "through an index formula that's a simple ratio: the number of Advanced Placement, International Baccalaureate and Advanced International Certificate of Education tests given at a school each year, divided by the number of seniors who graduated that year. A ratio of 1.000 means the school had as many tests as graduates."
