J. L. Mann High Academy, Greenville High Academy, and Riverside High School are listed among The Washington Post’s listing of America’s Most Challenging High Schools.
America’s Most Challenging High Schools ranks schools through an index formula using this 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.
The index ranks for the three GCS schools are:
- J. L. Mann High (Ranking 743) – E&E% (38); Lunch (33); Index (3.027)
- Greenville High Academy (Ranking 864) – E&E% (66); Lunch (53); Index (2.784)
- Riverside High (Ranking 1,401) – E&E% (31); Lunch (18); Index (2.045)
The index ranks high schools by the number of Advanced Placement, International Baccalaureate, or Cambridge tests given at a school each year, divided by the number of seniors who graduated that year. Schools ranked no. 220 or above are in the top 1 percent of America’s 22,000 high schools, no. 440 or above are in the top 2 percent and so on.
The E&E% column shows the percentage of all seniors who passed at least one AP, IB, or Cambridge test some time in high school. The Lunch% column gives the percentage of all students whose family incomes are low enough to qualify for lunch subsidies.
