NAR stands for the National Association of Realtors and is the largest trade organization in the world.  The NAR promotes ethics and education in the real estate industry.  Many of the state laws designed to promote professionalism and improve ethical standards begin in the NAR’s REALTORS Code of Ethics and Standards of Practice.  The NAR’s fundamental strength is the local association or REALTORS.  These local associations are organized across the nation.  Each real estate brokerage makes the decision regarding whether to join a local association or REALTORS.  If a particular real estate brokerage belongs to an association, all of the associates in that brokerage must also join the association.
