1. Know the scoresheet.
This is usually talked about at a tryout meeting or posted online. You can also always email the coach to inquire how tryouts are scored specifically. For example: If a school uses a scoresheet from NCA (like the image below), tumbling is only worth 5 points out of 35 total. That is 1/7 only! Therefore, tumbling points can be easily made up through the cheer, dance & jumps compared to a girl that has a full but cannot complete the cheer or dance successfully. I've given you an example of how 4 different tryout contestants scored in each category, and how it effects their overall result. #1,2 & 3 would probably make the team, where as #4 would not (as the natural break between scores is before #4).
#1 is a pretty average tryout. They were good but nothing stood out as exceptional.
#2 is the strongest tumbler. She is talented skill wise, but could not remember the words or motions & had to stop and start her cheer several times. Her crowdleading skills need work.
#3 only has a cartwheel, but is a great crowdleader. She is extremely loud, spirited & sharp in her motions.
#4 just does not have the technique yet in her skills. She was very quiet and unsure of herself.
2. No matter what scoresheet you have, Execute skills cleanly with correct technique.
A lower jump with clean technique will score better than a high jump with incorrect technique.
A scary looking backtuck will give a worse impression than just doing a clean, nicely executed backhandspring.
etc. etc.
3. Be confident, smile & practice practice practice!
Know the tryout materials by heart. Be able to perform them in front of others (your family, friends, anyone that will watch you) without having to stop and think of what comes next. Then once you are confident with the materials, smile and have fun out there! We want to see that you are enjoying yourself, not running off to cry in the corner because you are in front of the crowd or you made a mistake & can't recover.
