While one Lilburn high school is seeing an increase in its graduating students, another has seen a slight decrease.
According to data released this week from the state Department of Education, Berkmar High's graduation rate has increased more than 10 percentage points, from 47.68 in 2011 to 57.75 percent in 2012.
Parkview High on the other hand isn't seeing that type of increase. While it's still higher than Berkmar's, the orange-and-white school has a graduation rate of 86.94 in 2012, a 0.34 percentage drop from the 87.28 percent it had the year before.
As a county, Gwinnett County's graduation rate increased more than three percentage points -- from 67.56 in 2011 to 70.98 percent in 2012, according to data released this week from the state Department of Education.
In comparison, state averages increased from 67.44 percent in 2011 to 69.72 percent in 2012. In both years, Gwinnett County beat the state average.
This marks the second year that Georgia has used an adjusted cohort rate to determine graduation rates. Currently, the state uses a four-year method, which tracks the number of students who graduate in that time frame.
It also includes adjustments for student transfers. The calculation is based on federal standards that allow all states to equally compare graduation rates across the nation.
