One Licence That Works in Forty States
Professional licensing is issued state by state, which means a qualified worker crossing a border may be unable to practise. Interstate compacts let member states recognise each other credentials, and they have spread quickly.
The Problem Federalism Created
Occupational licensing is a state function, so a nurse, physician, physical therapist, or counsellor holds a licence valid in one state. Moving means applying again, meeting that state specific requirements, paying fees, and waiting.
For most of the twentieth century that was tolerable, because most people practised where they trained. Three developments made it a live problem.
Workers became more mobile. Telehealth made it possible to treat a patient in another state without moving, which raised the question of where the practice occurs. And military families, who relocate frequently and involuntarily, became a visible constituency bearing the cost.
Why Ordinary Reciprocity Failed
States have long had discretionary reciprocity or endorsement processes, under which a board may recognise an out of state licence.
Those processes are slow, discretionary, and inconsistent. They typically require a fresh application, verification of the original licence, sometimes additional coursework or examination, and a review by a board that meets periodically. Months of lost earning is a normal outcome.
An interstate compact is different in kind. It is a binding agreement among states, enacted as legislation in each, creating a legal framework under which a licence issued by one member state carries privileges in all of them.
| Reciprocity | Compact | |
|---|---|---|
| Legal character | Discretionary board decision | Binding interstate agreement |
| Process for the worker | New application in each state | One licence, multistate privilege |
| Timeline | Months | Immediate or days |
| Standards | Vary by state | Uniform eligibility criteria |
The feature that makes a compact work is not the recognition, it is the shared infrastructure behind it: uniform eligibility criteria, a common data system, and an obligation to report discipline. Without those, states will not trust each other licences enough to recognise them automatically.
How They Are Structured
A compact defines eligibility, typically requiring a licence in good standing from a member state that is the licensee primary state of residence, a criminal background check, and no current discipline or investigation.
It establishes a commission of member state representatives that administers the compact, adopts rules, and operates a shared data system recording licences and disciplinary actions.
Critically, it preserves state authority over practice. A practitioner working in a remote state under a compact privilege is subject to that state practice laws and its board disciplinary jurisdiction. The compact governs the licence, not the standard of care.
The Ones That Exist
Several compacts now cover substantial parts of the country. The nurse licensure compact is the oldest and largest, providing a multistate licence recognised across member states. The interstate medical licensure compact takes a different approach, expediting the issuance of separate full licences rather than creating a single multistate one, which reflects physician boards preference for retaining individual licensure.
Compacts also exist for physical therapy, psychology, emergency medical services, occupational therapy, counselling, audiology and speech language pathology, and others, with new ones enacted regularly. Several have been developed with funding support from the Department of Defense precisely because of the military spouse employment problem.
The Objections
Opposition is real and comes from identifiable sources.
State boards resist ceding authority, both on genuine sovereignty grounds and because licensing fees fund board operations, and a compact can reduce fee revenue.
Some professional associations oppose compacts on the argument that they lower standards to the level of the least demanding member state, since eligibility is defined by the compact rather than by each state.
There is also a competition dimension that is rarely stated openly. Practitioners in a state with restrictive licensing benefit from limited entry, and a compact admits competitors from elsewhere. The public interest argument against compacts and the private interest in restricting supply point the same direction, which makes the debate difficult to read at face value.
What the Evidence Suggests
Research on nurse licensure compact adoption has generally found increased cross border practice and improved supply responsiveness, particularly during shortages, without evidence of deteriorating quality or increased discipline rates.
That is a reasonably strong result for a policy this contested, and it is the main reason adoption has continued to spread.
The telehealth question remains the most active frontier. A clinician treating a patient remotely is generally regarded as practising where the patient is located, so compacts directly determine the reach of telehealth services, and their expansion has been driven substantially by that.
The Bottom Line
Interstate compacts solve a mobility problem created by licensing being a state function in a country where people move, by binding states to recognise each other credentials under shared standards and shared discipline reporting. They work better than discretionary reciprocity because they are legally binding and administratively automatic, and the evidence on nursing suggests they improve supply without harming quality. The opposition combines legitimate concerns about standards with a less legitimate interest in keeping competitors out, and the two are difficult to separate in any given hearing.
