In the 206th IAAF Council Meeting, held after the 2016 Summer Olympics, the council decided to conclude the world championship for under-18 athletes after the 2017 event. The decision was made with the intention of improving under-18 competitions at continental level instead.[2] The competition was renamed to the IAAF World U18 Championships in November 2015, though ultimately only the 2017 competition used this title.
The competition was the under-18 counterpart to the World U20 Championships, which are for athletes who are 19 years of age or under in the year of competition.
