This is the qualifications for figure. Bikini is the same I think. FBB is by weight classes and not height classes. As said before you have to compete and place in a national qualifier (NQ). National qualifiers usually have 5 height classes in figure. So you have to place in the top 5 of each height class to qualify for the Junior national shows and the top 3 at Nationals and USA. You can find all the rules at npcnewsonline(dot)com
