Fairfax County Public High Schools graduated 91.3 percent of its students last year, according to the Virginia Department of Education, beating out the statewide average of 88 percent.
The Class of 2011 had a 91.4 percent graduation rate, according to VDOE data.
In the Richmond Highway area, here is the graduation rate for local high schools:
Hayfield Secondary School had a 92.7 percent rate of graduation last year.
West Potomac High School had an 87.7 percent rate of graduation last year.
Mount Vernon High School had an 86.9 percent rate of graduation last year.
According to a release from Fairfax County Public Schools, the on-time graduation rate is based on four-years of data that factors in "student mobility, changes in student enrollment and the needs of special education and limited English proficient students."
For a student to graduate "on time" in 2012, they would have had to enter ninth grade in 2008-2009 and graduate in four years or less, earning a diploma recognized by the state's board of education. Those may include a general achievement diploma or special diploma.
"A total of 8,375 FCPS students, or 61.4 percent, obtained an advanced studies diploma in 2012, compared to the state average of 48.8 percent," FCPS reported.
