Foreword
As Special Legal Counsel for the National Center for Interstate Compacts it was both an honor and a privilege to serve as a principal compact drafter and member of the EMS National Advisory Panel to provide the legal framework, build consensus, and advance the national dialogue that made the United States EMS Compact a reality. It was also a privilege to assist in convening the inaugural meeting of the Interstate Commission for EMS Personnel Practice on October 10, 2017 in Oklahoma City.
Interstate compacts are not widely understood, although the EMS compact and other health occupational licensure compacts mentioned in this Guide have resulted in unprecedented use of compacts in a wide range of interstate regulatory purposes including licensure of EMS personnel. As science and technology have enabled people to travel the country virtually as well as literally, such mobility has also increased the need for accommodating health practitioners licensed across state lines to provide competent health care commensurate with the rapidly changing laws and regulations concerning the provision of telehealth to our highly mobile society.
As this Guide demonstrates, clinicians often cross state lines, not as an exception but as part of their day-to-day work, disaster response, or military service. The EMS Compact ensures clinicians can do so legally, safely, and efficiently without sacrificing public protection or clinical oversight. This Guide also illustrates that a national crisis such as the Covid-19 epidemic requires a licensure process in which compact member states could immediately recognize EMS licensees from other Compact states for the first time without requiring additional applications, processing delays, or redundant fees. A process which once took weeks was now needed to be instantaneous and as the result of the EMS compact, clinicians were quickly deployed across state lines with the legal authority to practice.
Donnie Woodyard has provided a comprehensive analysis of the EMS Compact, including chapters on How the EMS Compact Functions, Disaster Response and Mutual Aid, EMS Data Privacy and National Security, and Advancing the EMS Compact Together. His experience, knowledge, and insights give us an invaluable look from the inside and the impact of the EMS Compact on member states and the nation.
This Guide is an extraordinary resource for those involved in EMS work including clinicians and regulators, as well as legislative and executive branch officials and I am grateful that this definitive work has been made available.

Common Questions About the EMS Compact
Since Across State Lines was published, a number of claims about the EMS Compact have circulated in legislative debates and online sources — some accurate, many not. The questions below reflect what the historical record, statutory text, and six-plus years of operational data actually show. Answers draw on publicly available sources including the Compact's model legislation, the Commission's Administrative Rules, and the operational record documented at emscompact.gov.
Does the EMS Compact reduce local control over patient care?
No — the historical and operational record shows the opposite. The EMS Compact does not alter patient care protocols, medical direction, or system design. Under Administrative Rule 4.0(B), an EMS clinician may exercise a Compact Privilege to Practice only when performing official EMS duties assigned by an EMS agency already authorized to operate in the host state. Local protocols, scope of practice, and physician medical direction remain fully under state and local authority.
Rule 4.4 explicitly preserves host-state authority to modify scope of practice and require additional training. Host states may restrict, suspend, or revoke a Compact Privilege to Practice at any time to protect public health and safety (Rules 8.0–8.1). The Compact reinforces local control rather than displacing it.
Has the EMS Compact reduced wages or displaced workers?
After more than six years of implementation across 25 member states, there is no documented evidence that the EMS Compact has reduced wages, displaced workers, or systematically advantaged any category of employer. The Compact addresses individual licensure recognition only — it does not regulate employment, wages, labor relations, procurement, or collective bargaining, which remain governed by state and federal labor law and collective bargaining agreements.
Notably, one of the most frequent user groups of the EMS Compact is fire-based EMS, including career firefighter-EMTs and paramedics — particularly for wildland fire deployments, lateral transfers, and disaster response missions.
Can for-profit ambulance companies use the Compact to deploy resources across state lines without state approval?
No. The EMS Compact addresses individual EMS clinician licensure recognition only — not agency authorization. EMS agency operations remain fully subject to each state's licensure, permitting, franchising, certificate-of-need, and regulatory requirements. Section 15 of the model legislation explicitly states that nothing in the Compact supersedes state law or rules related to licensure of EMS agencies. An EMS agency operating within a state must continue to comply with that state's agency licensure and operational laws, independent of whether individual clinicians hold a Compact Privilege to Practice.
Is the EMS Compact Commission a governmental body subject to transparency requirements?
Yes. The EMS Compact Commission is defined in the model legislation as "a joint public agency" and "a body politic and an instrumentality of the Compact states" (Section 10(A)). The U.S. Supreme Court has repeatedly affirmed the governmental nature of interstate compact commissions, most directly in United States Steel Corp. v. Multistate Tax Commission, 434 U.S. 452 (1978) and Cuyler v. Adams, 449 U.S. 433 (1981).
Open meetings and public notice are mandated by the Compact statute itself (Section 10(B)(4)) — not a discretionary policy, but law. The statute requires advance publication of proposed rules at least 60 days before consideration (Section 12(D)) and public hearings when requested by 25 or more persons (Section 12(G)). Since October 2017, the Commission has publicly noticed 29 Commission meetings, 117 Executive Committee meetings, and 17 Committee meetings — all open to the public with public comment periods. See the Commission's full governance structure and bylaws at emscompact.gov.
Do states know the qualifications of EMS clinicians arriving from other Compact states?
Yes — and the EMS Compact gives states more information than they would have under traditional single-state verification. All Compact member states use the same nationally accredited educational standards, the same program accreditation requirements (CoAEMSP/CAAHEP), and the same national licensure examination (NREMT). The Compact's Coordinated Database provides member states real-time access to licensure status, privilege-to-practice status, investigatory information, and adverse actions across all member states (Rules 2.8; 11.0).
A clinician may exercise Compact privileges only if their home-state license is unrestricted, all eligibility criteria are met, and their privilege to practice is active and visible in the Coordinated Database (Rule 4.0(C)–(G)). Local agencies retain full authority to credential clinicians against agency-specific and medical-director-specific standards — the same process applied to any new hire regardless of state of origin.
Are background checks adequate for EMS clinicians practicing under the Compact?
The EMS Compact requires FBI-compliant biometric criminal history checks as a prerequisite for state licensure for all licenses issued after a state joins the Compact (Administrative Rule 4.7(A)(5)). There is currently no equivalent uniform requirement for non-Compact states. In December 2023, the Commission adopted Position Paper 2023-01 calling on all states, territories, and jurisdictions — including non-Compact states — to implement this standard. The Commission has also encouraged states to enroll in the FBI Rap-Back service for continuous monitoring.
In 2026, the Commission further strengthened this framework with Position Paper 2026-01: Criminal Convictions and Licensure of EMS Personnel, establishing a data-driven, constitutionally grounded framework for evaluating applicants with criminal histories — balancing public safety with due process and rehabilitation pathways. States retain full authority to determine whether a clinician may practice within their borders.
Can the EMS Compact Commission sell or share EMS clinicians' personal information?
No. Personally Identifiable Information (PII) is explicitly defined as protected under Administrative Rule 2.20. The Commission is prohibited from releasing or generating public reports containing PII and must ensure confidentiality and data security (Rule 11.4(C)–(D)). The Coordinated Database exists solely to support governmental licensure verification, investigations, enforcement, and disciplinary coordination among state EMS authorities — not for commercial use. Member State data remains the property of the originating state (Rule 11.0(B)(1)).
In 2025, the Commission adopted Position Paper 2025-01: EMS Workforce Privacy Protection, calling for robust safeguards against misuse of licensure data, restrictions on bulk data releases, and alignment with federal privacy standards including the Privacy Act of 1974.
Who wrote the EMS Compact model legislation?
The EMS Compact was developed through a federally funded process under a U.S. Department of Homeland Security contract awarded to NASEMSO (Contract HSHQDC-12-C-00128, September 2012). A multi-organizational National Advisory Panel of approximately 24 stakeholder organizations — including the International Association of Fire Fighters (IAFF), the International Association of Fire Chiefs, the National Volunteer Fire Council, the National Governors Association, and many others — provided policy guidance beginning in January 2013.
A 13-member Expert Drafting Team then translated those recommendations into model legislation. The Drafting Team included representatives from NASEMSO, the Council of State Governments, the Association of Air Medical Services, the IAFF, the National EMS Management Association, the National Association of EMTs, and Vedder Price Law Firm (legal advisors). The model legislation was approved and released for state consideration in June 2014 as a consensus document on behalf of all drafters. The Commission's official EMS Compact history documents this full timeline. Across 25 member states, more than 3,250 state legislators have voted in favor of EMS Compact legislation, with a 98% approval rate.
Does federal law support the EMS Compact?
Yes, at multiple levels. The Servicemembers Civil Relief Act (50 U.S.C. § 4025a), as amended by the Veterans Auto and Education Improvement Act of 2022, explicitly defers to interstate licensure compacts — including the EMS Compact — for military EMS licensure portability in member states. The U.S. Department of Justice notified all State Licensing Authorities of this provision in July 2023.
The U.S. Department of Defense designates occupational licensure compacts as the "gold standard" for license portability and tracks the EMS Compact by name in its Support of Military Families (SoMF) scorecards. Compact participation accounts for 50% of a state's spouse employment score in DOD assessments that inform base realignment and investment decisions. The CMS Rural Health Transformation Program (Public Law 119-21, $50 billion, 2026–2030) includes licensure compact participation as a scored criterion in state grant applications.
Does the EMS Compact create tax issues for states?
No. The EMS Compact does not affect taxation. It does not create new employment classifications, payroll mechanisms, tax exemptions, or special treatment for EMS clinicians or employers. Income taxation, withholding, and employer tax obligations remain governed entirely by existing state and federal tax law. There are currently more than 270 interstate compacts in effect in the United States, including approximately 18 occupational licensure compacts — none of which create separate tax regimes or disrupt state revenue authority.
