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

The MCB has updated our trainings to an online platform and all upcoming trainings can be found on our training calendar at www.missouricb.com

This includes the “live” ethics requirement– The MCB has suspended the requirement that ethics trainings be live indefinitely. The MCB will accept any ethics training a professional takes until further notice—please just make sure the session has the word “ethics” in the title.
