CAAS Standards Version 4.0
The CAAS Standards Version 4.0 are the latest, ANSI-approved national standards for EMS accreditation. Developed to elevate operational excellence, clinical quality, and organizational accountability, Version 4.0 reflects modern EMS expectations and evolving industry realities.
With a reorganized structure and expanded requirements addressing today’s challenges—such as cybersecurity, implicit bias, and employee wellness—Version 4.0 sets a clear benchmark for EMS agencies striving to achieve the highest level of care, safety, and compliance.
This comprehensive guide is divided into four sections—Administration, Clinical, Operations, and Special/Other Services—to ensure clarity, practical navigation, and relevance across diverse agency sizes and service models. Whether you are pursuing accreditation for the first time or transitioning from a previous version, the Standards provide the framework for meeting CAAS requirements.
