In September, Carey was selected to represent the United States at the 2017 World Artistic Gymnastics Championships in Montreal alongside Ragan Smith, Morgan Hurd, and Ashton Locklear. On the first day of competition, Carey competed only on floor and vault. With clean performances on both, she qualified in third place for the floor exercise final (14.100), behind Smith and Mai Murakami of Japan, and second in the vault final, behind reigning world champion Maria Paseka of Russia.
