Top 10 Things to Know About CAAS Standards 4.0: What You Need to Know


The Commission on Accreditation of Ambulance Services (CAAS) has officially released Version 4.0 of its national accreditation standards—a major update designed to reflect current industry practices, technology, and community needs. Whether you’re a newly accredited agency or preparing for reaccreditation, here are the top 10 takeaways from the recent webinar outlining what’s new and what’s changed:

1. Completely Redesigned Structure

Version 4.0 is more than just an update—it’s a complete overhaul. The new layout, numbering system, and merged documentation make it easier to read and apply. A crosswalk is available to help agencies transition from Version 3.0.

2. Reorganized and Expanded Sections

The standards have grown from two to four main sections:

  • 100: Administration
  • 200: Clinical
  • 300: Operations (new)
  • 400: Special/Other Services (new)

The number of characteristics has increased from 107 to 147, reflecting a broader scope.

3. Historical Performance Matters

Version 4.0 puts a spotlight on performance over time. Agencies will need to show a three-year history for licensure, strategic planning, clinical performance, employee feedback, education, and data tracking.

4. Modernized Language

Outdated terminology has been replaced with industry-relevant language. References now include electronic records, cybersecurity, and social media. Standards around diversity are community-focused rather than prescriptive.

5. Expanded Focus Areas

The standards now go deeper into:

  • Adverse event reporting
  • Medical record tech (ePCRs)
  • Leadership development and succession planning
  • Implicit bias education
  • Recruitment, retention, and organizational safety culture

6. Brand-New Standards

Version 4.0 introduces standards covering:

  • Driver monitoring
  • Technology vulnerability and response
  • Service and non-service animals
  • Detailed facility requirements (including showers and laundry)

7. Stronger Emphasis on Tech & Security

Technology and information security get much more attention, including vulnerability assessments and response plans. Cybersecurity is no longer optional—it’s an operational imperative.

8. Updated Minimum Staffing Standards

The minimum required staffing now allows for one EMT and one Emergency Medical Responder (EMR) under certain conditions—expanding flexibility for agencies.

9. Refined Medical Direction

New details clarify the roles and qualifications of the Agency Medical Director, distinguishing it from external medical direction and outlining specific training expectations.

10. Section 400: Special/Other Services

If your agency offers services like dispatch, specialty transport, or mobile integrated health, you’ll need to meet Section 400 standards. Agencies self-report services provided, but on-site reviews will confirm.
