Croquet Referee Video Links (US Rules)
(Many of the shot faults also apply to Golf Croquet and Association Croquet)
Bob Kroeger and Ted Prentis created a USCA 6 Wicket American Rules Croquet Referee On Court Video Series designed to help aspiring referees prepare for the on court test. This series should also help current referees of all levels. Additionally, USCA members who do not want to become referees may value from watching this series to better understand what a referee is looking for when called out to make a ruling. (We thank two USCA members/referees who generously funded this project, Michael Charrier and Harvey Geiger. We hope you find this a worthwhile and helpful video series.)
