The data from the state showed the graduation rate for Buford High's black students was 90.6 percent, 86.1 percent for Hispanic students and 94.9 for white students.
As for students with disabilities, that number is 56 percent.
There were too few students who identify as multi-racial along with Asian or Pacific Islander to record data.
The increases come as Georgia has changed graduation test requirements and as many schools have increased the use of online classes in which many students earn credit without mastering the material. Georgia eliminated its High School Graduation Test starting with the class of 2015. Now high school students must take state tests in certain subjects, but they don't have to pass the tests to graduate.
In recent years, many districts too have paid more attention to tracking down students who leave school before graduation in an effort to keep them in school—and avoid identifying them as dropouts which would bring down graduation rates.
