ICAA currently uses the SI Play platform to register, collect fees and communicate with teams, parents and athletes.  ICAA will make every effort to promote, communicate and allow a reasonable time frame for registration; however, due to the nature of administering to so many athletes, you will be assessed a late fee if you sign up past the stated deadline.  Registration after the deadline is not guaranteed and is determined on a sport-by-sport basis.
