Between January 1, 2013 and December 31, 2016, every Realtor® is required to complete 2 1/2 hours of Code of Ethics training. NAR offers a free course.
Training opportunities are available from a variety of sources including courses/programs available from local associations, proprietary programs, NAR’s online course, and others. Go to http://www.realtor.org/code-of-ethics/training for NAR's free course. You do have to log in to this site in order to access this course. If you would like to receive continuing education in Virginia, there is a paid option as well.
Additionally, a course you may have taken for ethics continuing education may have already satisfied this requirement. You will have to check with the course provider to see if the course also qualified for NAR quadrennial ethics.
