The Veterinary Medical Board is currently auditing RVTs for CE.  RVTs have had their licenses suspended due to lack of the 20 required hours every 2 years.  Make sure that you complete 20 hours of CE prior to renewing your license.  16 of the hours must be approved and interactive, while 4 hours may be passive, like reading journals or viewing videos.  Newly licensed RVTs are exempt from the requirement for their first renewal.
