Why is YPT (article link) so important? Because a safe environment is best achieved when everyone is trained and fully aware, whether explicitly required or not. Troop 21 and BSA take this seriously and so should you.
Training can be done quickly online; go to myscouting.org and log-in or create an account. Upon completion, give a copy of your YPT certificate to the Troop 21 Training Coordinator: Marla Gordon.
