We give tests/quizzes at the orientation/initial training sessions. That is for all safety as well as food safety. We have a lot of hazards in our workplace, so occupational safety training is extremely important. People are required to pass with an 80 or higher. If they do not pass the test, they get the training presentation again and are re-tested.
Since we are rigorous in our initial training, we only have refresher training every year. No tests, but the same presentation (or an updated one) is given. Sometimes we do some extra sanitation/hygiene training at production meetings that is not the same as the full orientation training. All that is documented.
HR keeps the tests, but I keep scans of them. I have signed participation sheets for all the training sessions.
