Locum Tenens vs. Travel Nursing vs. Contract Staffing: What's the Difference?

If you've spent any time trying to fill a clinical vacancy, you've probably heard these terms used almost interchangeably. Someone on your team says "let's get a travel nurse," someone else says "just bring in a locum," and a third person asks whether a contract hire is the same thing as either. They're related, but they're not the same, and picking the wrong one can cost you time and money on a gap that needs a much simpler fix.

This isn't just semantics. The staffing model you choose affects how fast you can fill the role, how much flexibility you have, and what it costs. At Source EQ Staffing, we get asked to explain the difference almost every week, so we put together a clear breakdown of what each term actually means, and how to tell which one fits the gap you're staring at right now.

Contract Staffing, Defined

Contract staffing is the broadest term of the group, and the other three sit underneath it. It simply means bringing on a clinical or non clinical professional for a defined term, rather than as a permanent employee. The term can be a few weeks or several months. The role can be clinical (RNs, NPs, physicians, behavioral health clinicians) or non clinical (billing, intake, administrative support).

What makes contract staffing useful is the flexibility. You're not committing to a permanent salary and benefits package, and you're not stuck in a lengthy traditional hiring process while your unit runs short. A well run contract staffing desk, like the one at Source EQ Staffing, sources from an existing screened network, so a role can move from "we have a gap" to "someone credentialed is working it" in a matter of days rather than months.

Travel Nursing, Defined

Travel nursing is a specific type of contract staffing built around a nurse who relocates, or commutes a significant distance, for a temporary assignment, usually 13 weeks but sometimes shorter or longer. It grew out of hospitals needing to cover seasonal surges, like flu season in the Northeast or snowbird population swings in Florida and Arizona, without permanently expanding headcount.

Travel assignments typically come with housing stipends or provided housing, along with the pay rate, which is part of why they attract nurses willing to move for a few months at a time. From the facility's side, travel nursing is the right tool when you need coverage for a defined block of time and you're comfortable pulling from a national pool rather than a strictly local one.

The trade off is that travel assignments usually come with a minimum commitment on both sides, generally the full 13 week block, so they're not the most efficient fit for a shorter or more open ended gap.

Locum Tenens, Defined

Locum tenens is Latin for "to hold the place of," and it refers specifically to physicians and, in some cases, dentists or advanced practice providers, filling in temporarily for another provider. Locum coverage is common when a physician is on leave, a practice is between permanent hires, or a rural or underserved area needs coverage that the local market can't supply on its own.

Locum assignments range from a single day of coverage to several months, and they're built around continuity of patient care rather than filling an hourly shift. A locum physician needs privileging, malpractice coverage, and often state licensing handled before their first day, which is part of why working with a staffing partner who manages that compliance layer matters so much for this category specifically.

Per Diem, and How It's Different From All Three

Per diem sits slightly outside the contract, travel, and locum trio, and it's worth mentioning because it often gets lumped in with them. Per diem staffing means someone picks up individual shifts as needed, with no ongoing commitment on either side. It's the right fit when you need occasional coverage, not a sustained gap. A unit that's mostly fully staffed but needs an extra set of hands on Saturday nights is a per diem situation, not a contract or travel one.

Which One Do You Actually Need

The honest answer is that most hiring managers don't need to memorize this table. What they need is to describe the gap accurately, and let a staffing partner match it to the right model. That said, a few quick questions can point you in the right direction before you even make the call:

• Is this a single, defined vacancy with a known end date, like a leave of absence or a notice period? That's usually straightforward contract staffing.
• Do you need to cover a whole program or facility for a seasonal stretch, and you're open to a national candidate pool? That's travel territory.
• Is the gap specifically a physician or provider role, tied to patient continuity rather than shift coverage? That points to locum tenens.
• Are you mostly staffed, just short on certain shifts? Per diem is the leaner fit, and often the cheaper one too.

This is also exactly where a generalist staffing model can slow you down. A firm that only does high volume travel placements will try to fit your gap into a travel assignment even if a shorter contract would serve you better and cost less. This is one of the reasons Source EQ Staffing works across all four models under one desk, with one point of contact, so the recommendation is based on your actual gap rather than whichever model the agency happens to specialize in.

It's also worth saying that screening quality matters just as much as picking the right model. A contract RN or locum physician who is technically qualified but doesn't fit the team's pace or communication style creates the same disruption as an unfilled vacancy, just with extra steps. That's why every placement at Source EQ Staffing goes through The EQ Factor, our screening process that looks at fit and staying power alongside license and credential verification. The right model gets someone in the door fast. The right screening is what makes them actually work out once they're there.
