All adult officials will need to complete the following steps to be certified for the 2024 season:

  • Pay your CWLOA chapter dues. Adult Fee $60 for Early Bird Rates before 1/2/2024; $75 for LATE Registration starting 1/3/2024
  • CHSAA Membership fee is a fee of $10 paid to CWLOA from Official’s doing CHSAA games. This fee is to cover membership dues that CHSAA will bill us for at the end of the season. Note: you will include this when you pay your dues.
