Of the 23 high schools in the Gwinnett County School District, twelve are included in U.S. News and World Report's rankings of the nation's best public schools

The annual rankings measure schools in four major categories: student-teacher ratio, college readiness, math proficiency and English proficiency.

Gwinnett School of Mathematics, Science and Technology is Gwinnett County's top-raked school (ranked No. 1 in the state, No. 4 in the nation) with a college readiness score of 100.0, mathematics score of 3.3 and a reading score of 3.9 -- all above average for Georgia. The school was named the state's "most challenging" school earlier this year.

North Gwinnett High School (ranked No. 14 in the state) and Brookwood High School (ranked No. 16 in the state) are the second- and third-best high schools in Gwinnett County, respectively.
