The registration process varies depending on the team or program that your child is intending to participate in. There is an online site that you can use to register and pay fees that can be found here: Online Registration.
Registration for different programs is available at different times of the year. See the page for your intended program for details on the timing of registration.
Also, for teams that require tryouts, please ensure that your child successfully completes tryouts and is selected for a team before completing the registration process and paying fees. See the page for your intended program to determine if tryouts are required.
