Survey Vendor Participation Process for New Vendors

Step 1 — Vendor submits Vendor Participation form

  • Review the minimum business requirements for survey vendors and confirm your organization meets these requirements.
  • When the vendor application period is open, complete the participation application. Include, in detail, all subcontractor relationships. Fully document how you’ll fulfill the minimum survey vendor business requirements. Submit your application to the CAHPS for ACOs Survey Project Team during the registration period. Survey vendor participation for the 2019 survey administration period was open from February 27, 2019 to March 20, 2019.

Step 2 — Vendor successfully completes training

  • Approved applicants (vendors’ and subcontractors’ key staff) must participate in all CAHPS for ACOs Survey Sessions.

Vendors whose applications are approved, successfully participate in training, and pass a quiz incorporated into the training sessions can become approved vendors. The final list of approved CAHPS for ACOs Survey vendors is now available on the approved vendor list page.

Approved vendors must follow the procedures in the CAHPS Survey for ACOs Quality Assurance Guidelines to maintain their status as a CMS-approved vendor. The vendor application period for the 2019 survey administration is now closed.


The Consumer Assessment of Healthcare Providers and Systems (CAHPS) for ACOs measures experience of care for ACOs participating in Medicare initiatives. It is based on the Clinician and Group (CG CAHPS) survey and includes additional program specific survey questions.
