Are you talking about the mobility score to move from level 7 to level 8? If so, this is set by USA Gymnastics, and it is 31 All-Around. BUT most gyms would expect a higher score than that to be able to safely move onto level 8 skills and competition.
Each state has its own set qualifying scores for sctional, state etc. for moving from one level to another there is a minimum set by USAG but most gyms in my area usually all have their own extra requirements. Most of the gyms I know also have they must qualify for States to move up a level and have a score of 34 or higher to move up a level. some score requirements are more some are less.
