I just had my firearms licence upgraded. In a two part exam, I received scores of 96% and 92%. I had to receive a score of at least 80% in both to pass. I did not take the Canadian Firearms Safety Course, as it was not required, but did read the training text book from cover to cover. Having passed I will have to renew the licence after 5 years.
Now, as an on-ice-official with my credentials coming from Hockey Canada, I have to attend a recertification clinic every year. The course lasts about 8 hrs and I have to pass a test that requires me to achieve a score of 90%. I also get supervised at least twice a year to show that I can still skate, know my positioning and call a game properly.
Go figure!
