Sports teams are called the Raiders, and they compete in the Ohio High School Athletic Association as a member of the All-American Conference.

Athletic programs include football, baseball, fastpitch, basketball (men's and women's), soccer (men's and women's), bowling, swimming and diving, volleyball, golf, tennis, track and field, and cheerleading, with talks of forming a lacrosse team.

There are various types of choirs at Harding, including the madrigals and new tomorrows where the students dance and sing on stage.

Each year FIRST creates a new game/challenge, and every team has six weeks to design and manufacture a robot to complete the given tasks.

In 2012 the team won the school's first state championship in the activity, led by senior Michael Coates.
