Oakcrest's award-winning Science Olympiad team is a popular extracurricular at Oakcrest. The team has advanced to the Virginia State Science Olympiad tournament for the past four consecutive years, fielding its first Middle School team last year. In 2019, Oakcrest was the first all-girls team in history to compete in the Virginia State Science Olympiad tournament, finishing in the top ten in the categories of Designer Genes, Fossils, and Protein Modeling. Oakcrest science teacher and Science Olympiad moderator Dr. Kat Hussmann also received the 2019 Virginia Science Olympiad Coach of the Year award. In the 2020 regional competition, Oakcrest took first place among eleven high schools in the Anatomy and Physiology competition, and fourth in the Detector Building category. The Oakcrest team once again medaled in multiple events at the 2022 regional competition, including first place in Gravity Vehicle, second place in Forensics, and fourth place in Chemistry Lab and Ping Pong Parachute.
