As per the CNS Sanctioned Event Athlete Crossover Policy (here).
Competitive allstar athletes may not participate/compete on two (or three) teams if the separation between any of the levels the athlete is on exceeds 3 levels at the SAME event from the SAME program (multi-location gyms can be considered separate programs under exception 7) at a single Cheer Nova Scotia Sanctioned Competition. There are several exceptions to this policy that can be found in the official policy document.
If you are requesting an exception to the crossover rule, or any other rule, for the purposes of a one-time exception-based circumstance, please submit this form FOR APPROVAL.
NOTE THAT SUBMISSION DOES NOT AUTOMATICALLY EQUAL APPROVAL.
CNS will notify you if your request is approved or denied.
