Amanda moved up to the senior elite level for the 2010 season; although she was fifteen at every competition she competed in. On March 21, 2010, Jetter was named to the 2010 City of Jesolo Trophy team. Later in the month, Jetter travelled with the team to Venice to compete at the competition. She contributed to the team in the all-around with a score of 55.450. Later, in July, Jetter competed at the U.S. Classic in Chicago and was second in the all-around. In August, Amanda travelled to Hartford, Connecticut for the National Championships. However, in a training session on the day of the first day of competition, Jetter strained her achilles and was forced to withdraw from the competition. Jetter petitioned to be added to the 2010-11 U.S. National team and to attend the 2010 World Artistic Gymnastics Championships training camp, which was successfully accepted. Jetter wasn't named to the 2010 World Championships team.
