The membership of the team was selected at the 2015 USA Outdoor Track and Field Championships.

However, membership on the team was subject to the athlete achieving a qualification standard.

In addition, champions from the previous World Championships and the 2014 IAAF Diamond League receive an automatic bye.

The United States is part of the North American, Central American and Caribbean Athletic Association, which held its championship August 7–9, 2015 in San José, Costa Rica where 20 athletes qualified.

The final team membership as submitted to the IAAF was announced on August 10, 2015.
