Georgia's first Internet-based public school now has 4,400 students enrolled across the state.
Students of the Georgia Virtual Academy take all their classes online and do most of their work with the help of their parents.
They talk with teachers over the phone and on e-mail, and take state-mandated exams at the end of the year like other public school students.
The elementary and middle school students enrolled in the online charter school come form 163 of the state's 180 school districts. It is one of 173 virtual charter schools in 18 states.
Georgia Virtual Academy opened in 2007. Charter schools are funded with taxpayer money but operate independently and set their own goals for meeting federal No Child Left Behind standards.
