All but Walton and the Gwinnett school have selective admissions. And all but Davidson Magnet School have rates of low-income students far below the state average.
Gwinnett School of Mathematics, Science and Technology, which U.S. News ranked as the number-one school in Georgia last year was initially left off this year's list because of a database error, U.S. News said.
The rankings are based on how student performance on state tests compares to schools with similar proportions of low-income, black and Hispanic students. They also take into account graduation rates and how many students take AP exams and pass at least one.
Here are the top 20 high schools in Georgia, according to U.S. News:
