Gwinnett County graduated 67.56 percent of students in 2011, the year for which most-recent data is available from the state Department of Education.
The calculation is based on federal standards that allow all states to equally compare graduation rates across the nation. Georgia released its new calculation in April 2012.
The rate is calculated using the number of students who graduate within four years and includes adjustments for student transfers. (Data for 2012 will likely be based on a five-year cohort, and is expected to be released in spring 2013.)
Rates of neighboring districts, include: Barrow County at 64.22 percent, DeKalb County at 58.65 percent, Forsyth at 86.27, Fulton at 70.05 percent, Hall County at 72.73 percent and Walton County at 74.74 percent.
