RESO Certification Status

With the launch of RESO Analytics, the RESO Certification Map reflects a temporary Passed Current layer of certification that falls below Certified Current but ahead of Certified Legacy / Uncertified.

Passed Current represents the state between when an MLS vendor has passed technical testing on the latest standard(s) for an organization and when an MLS accepts those results as certified. Due to the new passed status, the lists that were on this page became incongruous with the certification map and RESO Analytics, and we are in the process of creating a meaningful solution here that shows the statuses of all MLSs, technology companies and brokerages in alphabetical order. Thank you for your patience.

For a list of all Certified Current organizations, please see RESO Analytics.
