The algorithm for measuring such standard is pretty simple: Researchers took the number of Advanced Placement, International Baccalaureate and Advanced International Certificate of Education tests given a year and divided that by the number of graduates at each school.
The Cobb County schools on the list are as follows:
183. Walton HS495. Lassiter HS755. Harrison HS936. Pope HS1058. Marietta HS1082. Campbell HS1133. Wheeler HS1184. North Cobb HS1206. Kell HS1334. Sprayberry HS1474. Hillgrove HS1523. Kennesaw Mountain HS1718. McEachern HS2001. Pebblebrook HS
