The quick answer from Indy is yes - however they are working on a way to allow 17yo's to take the test early (before turning 18) so that they may become compliant.:
"Question was: What about the athlete who is turning 18 after the March 23 deadline and before E/W and JO Nationals?
As it relates to those who are 17 right now, who will be turning 18 soon, we are working on communication to notify the parents that their child to begin to complete the course prior to the 18th birthday. The US Center for SafeSport has stated that all 18 year old’s must complete the course .
At this time, due to federal law, NGB’s cannot allow a 17 year old to complete the course with parental consent. USA Gymnastics is quickly working to develop a consent waiver for the course that can be provided to parents of 17 year old athletes, so that the 17 year old athlete will have the opportunity to complete the course prior to their 18th birthday.
The goal is to have this communication out in the coming days."
