After several successful competitions, Ferlito was chosen to participate in the 2015 World Championships. She qualified to the all-around final in 16th place with a total score of 55.665, and the Italian team qualified for the 2016 Summer Olympics in seventh place. On beam, with a score of 14.233 (difficulty: 5.7; execution: 8.533), Ferlito tied with Eythora Thorsdottir of the Netherlands (D-Score: 5.6, E-Score: 8.633). However, because Thorsdottir had the higher execution score, she earned the last place in the beam final over Ferlito. In the all-around final, Ferlito scored 14.441 on beam, the third-best score in that final (after Larisa Iordache's 14.766 and Shang Chunsong's 14.700). She finished in 12th place.
