Knowing how to choose a staffing agency, especially in healthcare, starts with looking beyond rates and sales claims. The right staffing agency should understand the position, explain how it sources and screens candidates, clarify responsibilities, support the staffing model you need, and provide clear contract terms.

For healthcare employers, the evaluation may also involve professional credentials, workplace responsibilities, and regulatory requirements. This 12-point checklist can help a hiring organization compare staffing agencies using practical criteria instead of relying on broad claims about being the “best” staffing partner.

Start With Your Hiring Needs Before Comparing Staffing Agencies

Before choosing a staffing agency, define the position the agency will be expected to fill. It is difficult to judge whether an agency is a good fit when the hiring organization has not established what the job requires.

Start with:

• Job description: What will the professional be expected to do?
• Required skills: Which qualifications are essential?
• Work setting: Where will the person work?
• Schedule: What hours, shifts, or coverage requirements apply?
• Credentials: Are specific licenses, certifications, or other professional requirements necessary?
• Duration: Is the need temporary or ongoing?
• Engagement model: Do you need temporary staffing, contract staffing, temp-to-hire, or direct hire?
• Start need: When would you like the selected professional to begin?

Your HR team should also separate required qualifications from preferences. That gives the staffing partner a clearer picture of the role and reduces unnecessary limits on the candidate search.

Facilities still deciding whether outside staffing support makes sense can review the signs your facility needs a therapy staffing partner.

12 Things to Check When Choosing a Staffing Agency

A practical way to evaluate a staffing agency is to review four areas: role fit, recruitment process, responsibility clarity, and agreement terms. If an agency cannot explain these clearly, employers may have difficulty comparing its services against another staffing provider.

Does the Agency Understand Your Industry and Roles?

Industry expertise should show up in the questions an agency asks, not only in its marketing.

A healthcare staffing agency should understand the types of professionals it recruits, the settings where they work, and the qualifications that may matter for those positions. Recruiting healthcare professionals can involve different role and credential considerations than staffing skilled trades, administrative employees, or other industries.

Ask:

• Which positions do you regularly recruit?
• Which healthcare or educational settings do you support?
• How do you distinguish required qualifications from preferences?
• What information do you need to understand this role?

The right staffing partner should be able to discuss the position in practical terms rather than rely on broad claims about expertise.

Does the Agency Understand Your Actual Hiring Needs?

A job title alone is rarely enough to run a focused candidate search.

The staffing agency should understand the work setting, schedule, required skills, desired experience, engagement model, and expected duration. If the job requires specific professional credentials, those requirements should also be clear before sourcing begins.

Pay attention to the intake process. An agency that begins recruiting before understanding the job description may be working from assumptions instead of the employer’s actual hiring needs.

How Does the Agency Source Candidates?

Access to candidates is one reason employers use staffing services, but the size of a database does not tell you whether an agency can source the right talent.

Ask how the staffing firm approaches recruitment for your type of position:

• Does it actively source candidates?
• Does its approach differ for temporary and permanent positions?
• How does it approach harder-to-fill roles?
• Does it recruit professionals with experience relevant to your setting?

The goal is not to uncover proprietary recruiting methods. It is to determine whether the agency has a defined talent acquisition process for finding potential candidates.

What Does the Screening Process Actually Include?

“Screened candidate” can mean different things from one staffing agency to another. Ask what the screening process includes and when each step occurs.

Depending on the role and agreement, the process may include:

• resume or application review;
• relevant experience review;
• schedule and availability discussions;
• role-specific qualification checks;
• professional credential verification;
• background checks;
• references;
• required pre-start documentation.

Do not assume the agency performs every step.

Ask what is completed before candidate presentation, what occurs before the professional starts, and which responsibilities remain with the hiring organization. In healthcare staffing, candidate screening, credential verification, exclusion screening, and facility onboarding can be separate activities.

Are Compliance Responsibilities Clearly Defined?

Employers should understand which responsibilities belong to the staffing agency, which belong to the hiring organization, and which may be shared.

For temporary workers, OSHA states that staffing agencies and host employers share responsibility for maintaining a safe work environment, with the exact responsibilities depending on the circumstances. OSHA also recommends that both parties clearly define their respective safety responsibilities in the staffing agreement.

Healthcare organizations may also have exclusion-screening responsibilities. The U.S. Department of Health and Human Services Office of Inspector General maintains the List of Excluded Individuals/Entities and advises healthcare entities to routinely check new hires and current employees against it. 

Worker classification is another area where labels alone are not enough. The IRS says employers should examine the actual relationship, including behavioral control, financial control, and the relationship between the parties. 

The useful question is not simply, “Does the agency handle compliance?” It is: Which responsibilities apply to this staffing arrangement, and who is responsible for each one?

Does the Agency Offer the Right Staffing Model?

Not every staffing agency supports the same types of placements. The right agency should offer an engagement model that fits the workforce need.

Hiring need	Model to consider
Short-term coverage	Temporary staffing
Defined assignment	Contract staffing
Temporary role with possible permanent transition	Temp-to-hire
Permanent position	Direct hire

Employers do not need to compare every detail of these models while evaluating the agency. They do need to confirm that the staffing firm can support the type of hire they intend to make.

For a deeper workforce comparison, see direct hire versus contract staffing for rehab departments.

How Does the Agency Evaluate Candidate Fit?

Candidate fit should be tied to the actual job rather than vague personality matching.

Relevant factors may include:

• required skills;
• applicable credentials;
• related professional experience;
• work setting;
• schedule;
• communication expectations;
• team structure;
• other job-related requirements.

Company culture can matter, but “cultural fit” should not replace clear, job-related criteria. Employers should describe the work environment and expectations precisely enough for the agency to understand what the position requires.

How Clear Is Communication During the Hiring Process?

Communication expectations should be established before the search starts.

Ask:

• Who will be the main contact?
• How will candidate information be shared?
• How should the employer provide interview feedback?
• What happens if job requirements change?
• How are scheduling issues handled?
• Who should the employer contact when a problem needs escalation?

Avoid equating fast responses with a better agency automatically. Communication should also be accurate, clear, and useful to the hiring process.

Are Pricing and Contract Terms Clear?

An hourly rate or placement fee is only one part of a staffing agreement.

Depending on the engagement model, employers may need to review:

• hourly or bill rate;
• direct-hire placement fee;
• minimum-hour requirements;
• overtime provisions;
• invoicing terms;
• cancellation conditions;
• temp-to-hire or conversion terms;
• replacement provisions;
• payroll responsibilities;
• agreement duration.

Payroll taxes, benefits, and employment responsibilities depend on the actual arrangement. Worker classification should not be determined simply by how someone is described in a contract; the IRS looks at the substance of the working relationship.

A common mistake is comparing one headline rate when the agreements themselves contain materially different terms.

Can the Agency Support Its Performance Claims?

Claims such as “high retention,” “fast placement,” or “strong candidate quality” need context. For example, “fast placement” may refer to the time it takes to present a candidate, not the time it takes for that person to complete screening, onboarding, scheduling, and the actual start. Employers should ask which milestone the claim measures.

If an agency shares performance data, ask:

• How is the metric defined?
• What time period does it cover?
• Which roles or clients are included?
• Does it cover temporary, contract, or direct-hire placements?
• Can the agency support the figure?

The same principle applies to fill rate, time-to-fill, employee retention, placement volume, and client satisfaction.

There is no single performance number that identifies the best staffing agency for every employer. The useful comparison is whether the measure is defined, supported, and relevant to your hiring needs.

What Support Continues After Placement?

Post-placement responsibilities can differ by engagement model.

Before signing an agreement, ask what happens if questions arise about:

• assignment changes;
• schedule changes;
• communication;
• contract administration;
• performance concerns;
• extensions;
• temp-to-hire conversion.

This is particularly relevant in temporary and contract staffing, where the relationship among the agency, worker, and hiring organization may continue after the assignment begins.

Is This the Right Long-Term Staffing Partner?

Finally, consider whether the agency fits both the current opening and the organization’s broader workforce needs.

Ask:

• Does it recruit the professionals your organization regularly needs?
• Can it support both temporary and permanent positions when needed?
• Does its geographic coverage fit your hiring footprint?
• Can it support recurring staffing needs?
• Does it adapt when role requirements change?
• Does its engagement model work for your HR team?

Some employers work with a single partner. Others use several agencies based on specialty, geography, volume, or position type.

Neither approach is automatically better. The right staffing partner is the one whose capabilities, process, and terms fit the organization’s actual hiring needs.

Who Is Responsible for What in a Staffing Relationship?

Responsibilities depend on the engagement model, applicable law, workplace, profession, and written agreement. Employers should clarify the division rather than assume a staffing agency handles every step.

Area	Staffing agency	Hiring organization
Define the job	Helps clarify requirements	Defines the position and hiring need
Source candidates	Leads recruitment as agreed	Provides role requirements
Evaluate potential matches	Screens or presents candidates as agreed	Makes selection decisions
Credential verification	May perform agreed checks	Confirms applicable role requirements
Background checks	May perform agreed checks	Responsibilities depend on the arrangement and applicable requirements
Workplace supervision	Depends on arrangement	Facility/worksite responsibilities apply
Workplace safety	Responsibilities may be shared in temporary staffing	Responsibilities may be shared in temporary staffing
Facility onboarding	May support agreed steps	Handles facility-specific requirements as applicable
Employment and payroll	Depends on staffing model	Depends on staffing model and agreement

For temporary staffing specifically, OSHA says the staffing agency and host employer are joint employers for workplace-safety purposes and recommends that their respective safety responsibilities be addressed clearly.

Employers should confirm the actual division of employment, payroll, safety, screening, credentialing, and onboarding responsibilities for their arrangement rather than relying on a generic staffing-industry assumption.

Common Mistakes When Choosing a Staffing Agency

Several common mistakes make agency comparisons less useful.

Comparing Agencies on Rate Alone

A lower hourly rate or placement fee does not tell you whether two agencies provide the same services or contract terms.

Starting With an Unclear Job

An incomplete job description makes it harder for any staffing partner to understand which candidates meet the actual need.

Treating Every Staffing Firm as Interchangeable

Agencies may differ by industry expertise, positions served, geographic coverage, engagement models, and recruiting approach.

Accepting Vague Screening Claims

Ask what “screened” means and which steps occur before candidate presentation or start.

Assuming One Party Handles Every Compliance Requirement

Safety, employment, professional credential, and screening responsibilities can depend on the arrangement.

Overlooking Conversion Terms

If a temporary or contract professional could later become a permanent employee, understand applicable conversion terms before the assignment begins.

Accepting Performance Claims Without Context

A percentage or placement number is useful only when you know what it measures.

FAQs

Is a Staffing Agency the Same as an Employment Agency?

The terms can overlap, but the services offered may differ. Some agencies focus on temporary or contract staffing, while others provide temp-to-hire or direct-hire recruiting. Employers should evaluate the actual engagement model and services rather than rely on the label alone.

Should a Company Work With One Staffing Agency or Several?

Either approach can make sense. One partner may simplify communication, while several agencies may provide access to different specialties, locations, or recruiting channels. The better structure depends on hiring volume, role type, geography, and the organization’s internal process.

Who Employs Temporary Workers?

In the temporary-worker model described by OSHA, workers are supplied to a host employer and paid by the staffing agency. Other staffing arrangements, particularly direct hire and some contract structures, can create different employment relationships, so employers should confirm the structure in the written agreement.

What Should an Employer Review Before Signing a Staffing Agreement?

Review the services provided, rates or fees, engagement model, payment terms, conversion provisions, cancellation terms, allocation of responsibilities, and any stated replacement provisions. For healthcare staffing, also clarify which party handles applicable screening, professional credential verification, and pre-start requirements.
