The Junior Olympic National Championships is the culmination event for the competitive season. The competition features 12 age divisions (Junior A, Junior B, Junior C, Junior D, Junior E, Junior F, Senior A, Senior B, Senior C, Senior D, Senior E and Senior F), which are determined by birth date. These gymnasts are vying to become Junior Olympic national champions in the all-around, as well as in all four events: vault, uneven bars, balance beam and floor exercise. The competition schedule will be determined closer to the event.

USA Gymnastics has eight regions, and the top seven gymnasts from each region’s Regional Championships advance to nationals. The winning regions will also be determined at the conclusion of the competition. The top four all-around athletes in each age division qualify to the 2018 Junior Olympic National Team and are invited to attend a national training camp.
