California is not a compact state when it comes to professional licensing because its regulatory boards and legislature have refused to hand oversight of nurses, doctors, therapists, and psychologists to multi-state commissions whose standards they consider weaker than California’s own. The label is a little misleading, though. California belongs to 31 interstate compacts covering water, criminal justice, education, and emergency management. What it has consistently stayed out of are the healthcare and professional licensing agreements that now cover most of the country.
The Licensing Compacts California Has Rejected
Nearly every major professional licensing compact has moved forward without California. The pattern is remarkably consistent across professions.
- Nurse Licensure Compact (NLC): over 40 states participate, giving registered nurses and licensed practical nurses a single multistate license. California is not a member.1NCSBN. NLC States
- Interstate Medical Licensure Compact (IMLC): roughly 40 states and territories have joined, offering physicians an expedited path to practice in multiple states. California has not joined and has not introduced legislation to do so.2Interstate Medical Licensure Compact. Physician License
- Physical Therapy Compact: 37 states are members. California has not introduced compact legislation.3PT Compact. PT Compact Map
- Counseling Compact: 39 states participate. California does not.
- Psychology Interjurisdictional Compact (PSYPACT): the majority of states have joined, enabling psychologists to practice telepsychology and conduct evaluations across state lines. California has stayed out.
A handful of other large states remain outside some of these agreements, but California’s absence is the most conspicuous because of its size and the sheer number of professionals affected.
Protecting Standards California Spent Decades Building
California is the most heavily regulated state in the country, with over 420,000 regulatory restrictions in its Code of Regulations.4Mercatus Center. California’s Regulatory Landscape That number is deliberate. California’s licensing boards have set requirements they consider higher than the national baseline, and joining a compact means accepting that professionals licensed under another state’s rules can practice in California without meeting California’s own.
Under a compact like the NLC, a nurse licensed in a state with lighter continuing education requirements or different scope-of-practice rules could begin working in California immediately. The California Board of Registered Nursing would lose the ability to screen that nurse through its own endorsement process first. For regulators who view that screening as the point of their job, that is not a trade they are willing to make.
Background Checks
California requires fingerprint-based background checks through the Department of Justice’s Live Scan system for professional licensure. Fingerprints must be taken by a DOJ-certified roller, and results are run against both state and FBI databases.5State of California – Department of Justice – Office of the Attorney General. Fingerprint Rolling Certification Combined fees run $74. The real sticking point is not cost. It’s that compact-licensed professionals from other states may not have undergone an equivalent screening. Accepting a multistate license means trusting another state’s vetting, which may not include the same depth of criminal history review.
Giving Up a Vote to an Interstate Commission
Every licensing compact creates an interstate commission with representatives from each member state. That commission writes rules binding on all members, and states generally cannot opt out of specific rules without leaving the compact entirely.6Occupational Therapy Licensure Compact. Rulemaking for Licensure Compacts For California, this is a hard sell. The state would get one vote alongside states with a fraction of its population and a very different regulatory philosophy, on rules that cover continuing education, disciplinary information-sharing, and practice requirements affecting patient safety.
Scope-of-Practice Conflicts
California often defines what licensed professionals can and cannot do differently from other states. Its nurse practitioner scope-of-practice rules, clinical supervision requirements, and specialty certification standards do not always line up with what compacts require. Joining could create conflicts between the compact’s uniform standards and California’s existing regulations, forcing the state either to weaken its rules or navigate a messy legal overlap.
What This Costs Professionals Moving to California
Because California stays out of these compacts, out-of-state professionals face a separate and slower path to practice. The practical impact varies by profession, but it consistently means more paperwork, higher fees, and longer waits than moving between compact states involves.
Nurses
A registered nurse moving to California must apply for licensure by endorsement through the California Board of Registered Nursing. The application fee is $350 for U.S.-educated nurses.7California Board of Registered Nursing. Endorsement Application Fees and Instructions Current processing time runs 10 to 12 weeks.8California Board of Registered Nursing. Processing Times In a compact state, a nurse with a multistate license could start on day one. Those 10 to 12 weeks are time the nurse cannot legally practice in California.
Licensed vocational nurses move faster. The Board of Vocational Nursing and Psychiatric Technicians lists a processing target of 3 to 4 weeks for endorsement applications.9Board of Vocational Nursing and Psychiatric Technicians. Processing Times
Physicians
Without IMLC participation, California requires physicians to go through the full licensing process with the Medical Board of California: verification of medical education, postgraduate training, examination history, and a complete background check. It routinely takes several months, compared with the expedited pathway available in IMLC states.
Teachers
Out-of-state teachers must hold a professional-level credential from another state or U.S. territory to qualify for a California teaching credential. Intern certificates, temporary documents, and apprentice-level credentials don’t count.10Commission on Teacher Credentialing. Out-of-State Applicants There is no direct reciprocity for career and technical education credentials; those educators must go through a designated subjects credential program in California. As of early 2026, the Commission on Teacher Credentialing was processing applications submitted before January 14, 2026, which gives a rough sense of the backlog.
The Workforce Cost
California’s refusal to join licensing compacts carries real workforce consequences, and nursing makes the stakes especially visible. State projections estimated California needed roughly 18,800 additional registered nurses in 2025, a statewide shortage of about 6%. By 2033, that shortage is projected to nearly triple, with the state needing over 61,000 additional registered nurses. Fifty of California’s 58 counties are projected to face nursing shortages.11Health Care Access and Information. Supply and Demand Modeling for California’s Nursing Workforce
Compact supporters argue that joining the NLC would give California hospitals immediate access to nurses already licensed in other compact states, especially for travel nursing and telehealth. Critics counter that an influx of compact-licensed nurses would not fix underlying problems like the geographic maldistribution of nurses across California’s counties. Both points have merit. The 10-to-12-week endorsement wait is still hard to defend when emergency rooms are short-staffed.
Will California Ever Join?
California has not ignored the question entirely. In 2024, Assembly Bill 3232 was introduced to enact the Nurse Licensure Compact, which would have brought the state’s Board of Registered Nursing and Board of Vocational Nursing into the NLC framework. The bill did not advance. No equivalent legislation for the Interstate Medical Licensure Compact or the Physical Therapy Compact has been introduced.
The failure of AB-3232 reflects a recurring dynamic in Sacramento. Proposals to join licensing compacts face opposition from the regulatory boards that would be affected, along with some labor organizations worried about increased competition for in-state professionals. Supporters, including healthcare systems and military-affiliated groups, argue that California’s isolation hurts patients and military families who relocate frequently. The opposition has carried the day so far.
The barrier is not procedural. The legislature could pass compact legislation in a single session. What’s missing is the political will to override the entrenched resistance of boards that view compact membership as a dilution of the standards they have spent decades building. Until that calculation changes, through worsening workforce shortages, federal pressure, or shifting legislative priorities, California is likely to remain one of the country’s most prominent compact holdouts.
