In addition to the quality assurance programs administered by REVAA member companies and other valuation providers, BPO Standards and Guidelines (BPOSG) have recently been introduced to provide a comprehensive framework for the preparation of BPOs on a national level.  They were developed by a BPO Standards Board comprised of BPO subject matter experts from leading BPO companies (including a substantial number of REVAA members), as well as experienced BPO practitioners.

The BPOSG includes suggested practices for the selection and utilization of comparable properties, pricing considerations, the use of photographs, and ethical and competency considerations.
