Derwael won the gold medal on the uneven bars at the Paris Challenge Cup. Then at the World Championships, she placed third on the uneven bars behind defending World champion Fan Yilin of China and first-year senior Elena Eremina of Russia. This made her the first Belgian female gymnast to medal at the World championships. She also placed eighth in the all-around final. Additionally, Derwael and Georgia-Mae Fenton of Great Britain successfully competed a difficult original skill (Stalder to Tkatchev with 1/2 turn), after which it was named after both of them in the code of points.
