Live Trainings:  With careful consideration, it has been determined it is best to cancel all upcoming MCB March and April trainings.  The Centers for Disease Control and Prevention are recommending social distancing when possible due to the COVID-19 virus.

Spring Renewals:  If you are renewing in April 2020 you will no longer be required to complete all your required educational hours; however, you will still need to provide a copy of your required ethics hours.  (You will however be allowed to do online ethics).

These changes are only in effect for this Spring April 2020 Renewal Date. For all future renewal dates including October 2020 you will be required to complete all required educational hours and “live” ethics trainings.
