MFTs, Psychologists and Clinical Social Workers: Where Portability Actually Differs

Marriage and family therapists often work beside psychologists, clinical social workers and counselors, sometimes in the same group practice seeing overlapping clients. When a practice starts to serve clients in other states, those colleagues can look like they have an easier path. For the most part, they do. The reasons come down to three things: compacts, education standards and the way supervised experience is documented.

Compacts: three professions in, MFTs out

Psychologists use PSYPACT, which provides a route for telepsychology and limited temporary in-person practice across participating states. Licensed professional counselors have the Counseling Compact, which issues privileges to practice in member states. Social workers have the Social Work Licensure Compact. MFTs are excluded from all three.

There is no MFT interstate compact. AAMFT weighed that option and in 2025 chose a model law, Access MFTs, instead. As of September 2026, 17 states are confirmed to have adopted it: Arizona, Arkansas, Connecticut, Georgia, Illinois, Iowa, Kentucky, Maryland, Minnesota, Nebraska, Nevada, North Carolina, Oklahoma, Rhode Island, Tennessee, Virginia and West Virginia. AAMFT reports 24 states in total with streamlined endorsement, including seven that got there on their own.

The structural difference matters more than the count. A compact gives a licensee a way to practice in other member states through one shared framework. A model law leaves each state issuing its own license. An MFT who wants to see clients in five states still needs five licenses.

Education and exam standards

Portability systems lean on uniform credentials. Psychology licensure has long rested on a doctoral degree and a national exam, which makes it easier for states to trust each other's licensees. Social work and counseling each have their own national exams and accreditation structures.

MFT education also has national accreditation, and there is a national MFT exam, but states have historically differed on required coursework and hours. Much of the friction in MFT endorsement came from boards re-reviewing an experienced clinician's graduate transcript against local course lists. Access MFTs addresses that directly: an applicant with an unrestricted independent license elsewhere, in good standing, is not re-reviewed on graduate coursework or supervised hours.

Supervised hours

Supervised experience requirements differ within every profession, but they bite hardest in endorsement when a board wants to verify hours completed years ago. Psychologists and social workers moving through a compact generally avoid that review. MFTs moving to a state without streamlined endorsement may face it, which can mean tracking down former supervisors or proving hours from a site that has since closed.

Composite boards blur the picture

Many states license MFTs, counselors and social workers through a single composite board. That makes it tempting to assume the professions share portability rules. They do not. Compact eligibility follows the license, not the board, so an MFT and a counselor licensed by the same office can have entirely different options for practicing in the next state over.

Planning a practice across states

For a mixed group practice, the practical consequence is that clinicians will be ready to serve clients in new states on different timelines. The client's physical location at the time of the session determines which state's license is required, so scheduling needs to account for who is authorized where. Budget more lead time for MFTs, start endorsement applications before the practice commits to a new market, and look first at states with streamlined endorsement. Confirm each state's current requirements with its board, because adoption status and board procedures change.
