There is a small, highly trained group of Realtors in the US who, by all industry and peer standards, represent the most qualified agents available for servicing the relocation market. Under the guidelines established by the Employee Relocation Council, a Realtor can apply to take the examination required for certification as a Certified Relocation Professional (CRP). The exam tests the applicants' knowledge of Family Relocation Issues, Relocation Tax and Legal Issues, Corporate Relocation Policies, Appraisal Methods for Relocation, and Relocation Real Estate Marketing. Most of the major US corporations require nothing less than a CRP to administer the needs of their transferees.
