[5] Roswell is a member of the Georgia High School Association (GHSA) and Region 4-AAAAAAA for athletic competition, as of the 2016–2017 academic year.

[18] Black students who progressed past grade 7 could then attend Washington High School in Atlanta.

During this growth, the Baptist, Presbyterian and Methodist churches also located on Mimosa Boulevard were used to house auxiliary classrooms.

[5] The new campus was expanded with a football stadium and softball field added in 1994 and an auditorium in 1995, paid for by the RHS Foundation.

[30] 26 Advanced Placement (AP) classes are offered, and SAT as well as ACT scores regularly exceed the national and state average.

The school's unique course offerings include the Career Tech diploma track, robotics, psychology, archaeology, and foreign languages.

[35] RHS students participated in the 2007 Annual Japanese Challenge Academic Bowl and won the most awards of any school at the competition.

[36] In 2007, RHS Senior Maia Bageant was named as one of 141 Presidential Scholars by the United States Department of Education.

[41][42][43] The Career Tech department at Roswell High is made up of Broadcast and Video Production, Cosmetology, Family and Consumer Sciences, Diversified Technology, Pre-Engineering, Business Education, and JROTC.

Courses cover diverse topics such as culinary arts, business, computers, interior design, and introduction to education and early childhood care.

Students in the program learn to produce everything from commercials and PSAs to dramas, news shows, and sporting events.

The advanced classes produce a weekly news show, the Morning Buzz, which airs at the beginning of the day.

The Broadcast and Video department supports the student-run radio station WRHS the Hive, the film club, and the yearly School House Rock concert.

These include performances at football games, murals painted in the school's halls, concerts, plays, and a spring musical jointly put on by the drama and choral departments.

[50] The Singing Hornets have performed concerts at Notre Dame, St. Peter's Basilica, Carnegie Hall, and Disney World.

[7][8] The Hornets have won multiple state titles in athletics, including three each in football and baseball, and two in boys' basketball.

[9] Since its inception, Roswell's traditional rival has been Milton, the oldest high school in northern Fulton County.

[2][56] The football series then went uninterrupted from 1970 to 1997 but was temporarily ended when the GHSA moved Milton to a different Region, which made scheduling difficult.

Milton ultimately ended up winning the state championship in extra innings by one run in front of an overflow crowd.

Sports offering varsity and JV teams include cross country, golf, soccer, tennis, and track and field for both genders.

[7][8] Every fall students are encouraged to wear their class colors on football game day Fridays to show their school spirit.

On Wednesday or Thursday night of Homecoming Week, students decorate the halls of the school by class to reflect the theme of the dance.

At every kickoff of the Friday football games, students anticipate the kick, each holding fistfuls of white flour.

As soon as the player kicks the ball, hands go up in the air, releasing the flour, creating a cloud of white to welcome the opposing team.

They would then beat Walton at home, which led to a rematch of the previous years semi-final match up against Lambert in the State Championship.

In Ray Manus Stadium, with over 5,000 fans in attendance, Roswell captured its first Boys' Lacrosse State Championship, defeating the Lambert Longhorns 6–5.

The team has been a state playoff participant and has been ranked nationally by such sources as USA Today Top 100 and Baseball America.

Established in 1983, The Sting is the school's official student newspaper and is a member of the Georgia Scholastic Press Association.

The monthly publication has been recognized on multiple occasions by the GSPA and the Henry W. Grady College of Journalism and Mass Communication at the University of Georgia.

The magazine is published once each semester and features student-created poetry, short stories, essays, photos, and artwork.
