The nominative registrations are in for the 2018 World Championships, and the USA's team consists of Simone Biles, Morgan Hurd, Riley McCusker, Grace McCallum, and Kara Eaker, with Shilese Jones as the alternate.

The nominative roster is subject to change and USA Gymnastics is expected to announce the final team on October 12, following the world selection camp which will be held October 10-12. The three-day camp includes a one-day competition on October 11 that will be live-streamed on the USA Gymnastics YouTube Channel.

Gymnasts in addition to the nominative roster who are expected to attend the camp are Jordan Chiles, Alyona Shchennikova, and Ragan Smith.

Senior national team members Jade Carey and Trinity Thomas were both invited to the selection camp but declined their invitations. 

According to USA Gymnastics, "Carey, who is the defending vault and floor exercise World silver medalist, and her coach, Brian Carey, want to pursue qualifying as an individual through the apparatus World Cup series, which precludes her competing on the 2018 World Team."

Below are the world selection team procedures via USA Gymnastics:

"The U.S. Women’s World Championships Team will have six athletes, including an alternate, and there may be one non-traveling alternate.  To be eligible, the gymnast must be at least 16 years of age during the 2018 calendar year. A minimum of eight athletes – the top two in the all-around rankings and a minimum of six additional athletes from among the competitors at the U.S. Championships and petitioned athletes – will be invited to the World Team Selection Camp, Oct. 10-13, at the interim training facility. The 2018 World Championships Team will be announced at the conclusion of the Selection Camp on Oct. 13. The final line-up of the five who will compete at the World Championships will be determined a minimum of 24 hours prior to the qualification competition. 

Criteria considered when selecting the team include: consistency – percentage of hit routines; results from past international and national competitions, including the U.S. Championships, GK U.S. Classic and American Classic, and World Team Selection Camp; D-scores for difficulty, and E-scores for execution; medal potential; composite strength of all team members, with consideration of potential for all-around and event medals; physical capability to fulfill the training plan; and readiness to compete.

The coaches for the 2018 World Championships Team will be the personal coaches of the team members following the final team selection, and the head and assistant coaches will be chosen from this group. Per the FIG rules, either the head or assistant coach must be a female.

The selection committee for the athletes and coaches is comprised of Tom Forster, high-performance team coordinator; Tatiana Perskaia; and Terin Humphrey, the athlete representative."
