She competed as part of the Swiss team at the World Championships in Nanning, China, where she qualified in 84th place, missing the all-around final.

Käslin then competed at the Arthur Gander Memorial in Chiasso in October, finishing in 6th place, and at the Swiss Cup a few days later where she teamed up with Pascal Bucher but failed to make team finals.

In May she performed at the World Challenge Cup in Varna, Bulgaria, where she won bronze on beam and gold on floor.

Käslin competed at the World Championships in Glasgow, where she posted an all-around score of 53.456 towards the Swiss team's 16th-place finish, ensuring them a spot at the Olympic test event in April 2016. Individually Ilaria finished 46th all-around in qualification.
