The IWLUB is the local board of US Lacrosse. In order to officiate games during the season you will need to become a US Lacrosse member. The cost is approximately $50. USL releases an online rules test during the first two months of the year. You will take this open book test online and submit your score to the local board before the beginning of the spring season. The IWLUB holds conference call Q&A which you are welcome to attend prior to submitting the test in order to rule related questions of an experienced official. There is no additional charge for completing the online test or participating in the conference call.
