In the United States, regulators and professional associations have spent centuries discussing and formulating interstate compacts – license reciprocity agreements intended to help solve issues with professional mobility between different jurisdictions.
Because most states have their own unique licensing ecosystems, professionals are frequently limited in their ability to travel across state lines, which can create barriers for access to services in underserved areas. Compacts aim to address this issue and promote unified standards of care across the board.
In this article, we’ll take an exhaustive look at existing interstate licensing compacts in the U.S. as well as some compacts currently in development and pending activation.
Interstate Medical Licensure Compact (IMLC)
The Interstate Medical Licensure Compact (IMLC) was first conceived by state medical boards in 2013, who at the time were beginning to take notice of how telemedicine would encourage more physicians to practice in multiple states. Over the course of a few years, state board officials laid the groundwork for the creation of an interstate agreement that would allow physicians more professional mobility
when practicing across state lines.
In the fall of 2014, the Federation of State Medical Boards assisted with the introduction of model legislation for what would become the IMLC. Over the next couple years, state legislators worked to implement the compact, which finally became operational in April 2017. Today, the compact includes 38 states as well as the District of Columbia and the Territory of Guam, with compact legislation currently introduced in six other states.
To participate in the compact and conduct work freely between member states, physicians must designate their State of Principal License (SPL), or the home state in which they hold a full medical license. Physicians must primarily reside in their SPL, conduct at least 25% of their practice in the SPL, be employed to practice within the SPL, and use the SPL as their state of residence for tax purposes.
After providing a formal Letter of Qualification from their SPL, physicians can apply to be credentialed through the IMLC, which also requires graduation from an accredited medical school as well as completion of certain licensure exams like the USMLE or the COMLEX-USA. Under the criteria for compact licensure as it stands, about 80% of U.S. physicians currently qualify. Though the compact operates under a Commission that administers the compact, licensure is still issued by compact states themselves.

Nurse Licensure Compact (NLC)
The origins of the Nurse Licensure Compact (NLC) date back over 25 years. In 1995, the National Council of State Boards of Nursing (NCSBN), recognizing inefficiencies in the traditional state-by-state nurse licensure system, caught notice of a report by the Pew Commission entitled “Reforming Health Care Workforce Regulation: Policy Considerations for the 21st Century.” This report argued single-state licensure would ultimately fail to meet the health care needs and expectations of the future.
Over the next few years, NCSBN worked to lay the foundation for what would become the NLC, starting with a mutual recognition licensure model in 1997. Two years later, the Council introduced the official compact, which focused on registered nurses (RNs) and licensed practical/vocational nurses (LPNs/VNs) and created uniform rules and policies for participating states. By 2000, Texas, Wisconsin, and Utah had become the first states to join the compact.
Over the next 15 years, the compact grew to include as many as 25 states, but growth reached a sudden halt as states grew concerned the agreement could not ensure adequate competence and education across the board. Potential new compact states were now worried the public could be endangered by a lower standard of practice in the nursing discipline if they joined. In response to this concern, NCSBN developed the Enhanced Nursing Licensure Compact (eNLC), which added uniform license requirements as well as background checks and new disciplinary provisions.
To date, 39 jurisdictions have passed legislation enacting the eNLC. Of these, Pennsylvania and the Virgin Islands are still awaiting proper implementation, and a host of other states, including Illinois, Massachusetts, Michigan, Minnesota, and New York, have introduced compact legislation but have not yet passed it.

Emergency Medical Service Officials Licensure Compact (EMS Compact)
The Emergency Medical Service Officials Licensure Compact (EMS Compact) originated in 2012 as regulators attempted to address the day-to-day issue of EMS personnel being deployed across state boundaries. For example, EMS personnel can be obliged to cross state lines to work if they are part of a multi-state agency or if they are staffing large unplanned events, among many other circumstances.
In 2013, a National Advisory Panel convened to establish guiding principles for the drafting of the compact. This panel comprised representatives from 23 stakeholder organizations, including the American Ambulance Association, the Federation of State Medical Boards, the National Association of EMS Educators, the National Registry of EMTs, the Federal Bureau of Investigation, and the USDA Forest Service.
Compact legislation was drafted, revised, and promoted over the following years. Activation of the compact required at least 10 states to implement the model legislation, and in 2020, at a meeting of the Interstate Commission for EMS Personnel Practice, this was finally achieved. Today, the EMS Compact comprises 22 member states and around 325,000 compact providers.

Psychology Interjurisdictional Compact (PSYPACT)
In 2011, the Association of State and Provincial Psychology Boards (ASPPB) established a task force to explore the use of technology in the field of psychology and how it would impact the profession in the coming years. By August 2013, the ASPPB Board of Directors had approved guidelines for the practice of telepsychology, which laid the groundwork for discussions regarding an interjurisdictional compact.
These discussions officially began in January 2014 with the ASPPB’s Telepsychology Advisory Workgroup, and by August 2014, the board had released an initial draft of the Psychology Interjurisdictional Compact (PSYPACT), model legislation allowing psychologists in constituent states to practice across state lines (particularly via telehealth) without applying for additional certification.
In August 2019, Georgia became the seventh state to enact PSYPACT (Arizona having been the first), triggering the formation of the PSYPACT Commission. As of January 2023, 34 states have enacted the compact.

The future of interstate licensing
As the need for professional mobility throughout the U.S. grows and evolves in response to changes in technology and service delivery systems, so too will regulatory approaches to interstate licensure. Whether multijurisdictional compacts are an appropriate substitute for unified, nationwide licensing systems remains to be seen, but as the development of agreements like the Teacher Compact and the Cosmetology Compact shows, the creation of compacts by regulators and professional associations will play a key role in the discussion of occupational licensing at large for years to come.
