Registration period for basketball begins on September 1st and runs through October 31st. Those registering before September 31st receive a $15.00 "early-bird" discount per child.

IWAA basketball is offered to boys and girls in grades 3 thru 8. Incarnate Word plays in the West County District of the CYC against other schools in that district. Teams are formed when entering the third grade. These teams are then kept the same from year to year. All Incarnate Word parishioners will be placed on an established parish team or will form new teams with other parishioners. New registrants that are not registered parishioners at Incarnate Word are welcome to join the program where space on established parish rosters permit. In the event of significant rostering issues, parishioners will be given priority over non-parishioners.
