Certification

RESO certifies systems to ensure they comply with real estate data standards. Certification ensures interoperability between technology systems that speak a common language. Standards provide that common language.

The Certification Process

  1. Pre-testing: Certification candidates should work with their technical staff or vendor to pre-test their systems with RESO’s certification tools. Pre-testing is essential to expediting certification. RESO staff is available to troubleshoot issues.
  2. Application and verification: Do not start a certification application until you have a confirmed, compliant RESOscript XML file from your technology vendor. Organizations who’ve passed pre-testing can apply for certification through the RESO website. RESO reviews the application for current membership status, a current signed Trademark Agreement, a signed Declaration, and agreement to the Certification Terms & Conditions (all docs available here).
  3. Certification payment: Certifications are complimentary for RESO members. Non-members should review the RESO Certification Fee Schedule.
  4. Compliance testing: RESO uses access credentials supplied by the applicant and/or applicant’s technology vendor and verifies standards conformance for the system.
  5. Certification: Applicants whose systems pass testing are provided with certificates from RESO.
