The Short Answer: What a CTS Actually Is
A CTS is a Certified Temporary-Staffing Specialist: a professional who has passed an examination demonstrating working knowledge of the legal and operational rules that govern temporary and staffing-services businesses. The credential is aimed at people who place, supervise, screen and manage temporary workers, and who need to understand where the staffing firm's responsibilities end and the client's begin.
The emphasis is practical and legal. Rather than testing abstract management theory, the certification tests whether you know how discrimination law applies to a staffing firm, how contracts with clients and workers should be structured, what makes someone an employer, and how leave, disability and drug-testing rules play out when a worker is employed by one company but working on another's premises.
If you have seen several different credentials abbreviated as "CTS," note that this article covers only the temporary-staffing credential. For other variations of the question, see our related explainers on what CTS certification is and what CTS stands for.
Who Issues the Credential
The credential is run by the National Association of Personnel Services (NAPS), a trade association serving the staffing and personnel-services industry. NAPS administers the online examination through its Certification Center. It also offers an optional Certification Immersion Class (CIC), where the examination is taken in paper-and-pencil format rather than online.
Two points about the issuing body shape how you should think about the credential:
- NAPS membership is not required. Nonmembers can certify, though they pay more (see the fee section below).
- Candidates must accept NAPS ethical standards and program rules. This is a condition of certification, not a formality, and it is part of what separates the credential from a simple knowledge quiz.
Because the program belongs to an industry association, the content reflects what staffing-firm owners and managers deal with daily. That is why the exam topics read more like a compliance checklist than an academic syllabus.
Who Holds It and Who Hires for It
The natural audience is people working inside temporary-service businesses: owners, partners, managers and employees who handle recruiting, placement, client contracts and worker administration. Account managers, branch managers, recruiters and compliance-minded operations staff all deal with the topics the exam covers.
NAPS's current CTS page also extends access to HR professionals and hiring managers, which broadens the audience to people at client companies who use temporary labor and need to understand the co-employment relationship. (The eligibility section below explains why this point deserves a careful read.)
Employers that value the credential are generally staffing and personnel-services firms, along with organizations that rely heavily on contingent workers. For a closer look at the job market, see our guide to CTS jobs, and for earnings context see the CTS salary guide. We do not quote specific salary figures here because no verified earnings data tied to this credential is available in the public program materials.
What the Examination Looks Like
The exam is built from three question styles, delivered as one timed test:
| Feature | Detail |
|---|---|
| Total questions | 150 |
| Question types | Multiple-choice, true/false and case-based multiple-choice |
| Time allowed | 2 hours |
| Correct answers required | 113, described by NAPS as 75% |
| Delivery | Online via the NAPS Certification Center; paper-and-pencil in the optional Immersion Class |
| Content updates | Manual and examination updated annually |
Two minutes per question is a workable pace for true/false and straightforward multiple-choice items, but the case-based questions take longer because you must read a scenario, identify the legal issue and then select the correct response. Practicing with scenario-style items matters more than memorizing definitions. If you want a deeper look at the difficulty, our article on how hard the CTS exam is breaks down what to expect, and the passing score guide covers the 113-question threshold in detail.
The 10 Preparation Topics, Explained
NAPS does not publish a weighted, formal exam blueprint. What it does publish are the preparation topics in its FAQ and in the description of the Certified Temporary Staffing Specialist Manual. Those topics are listed below as ten unweighted areas. Treat them as a curriculum map, not as an official domain count or a percentage breakdown. For a longer walkthrough of each area, see the complete guide to the CTS exam domains.
Domain 1: Laws of discrimination
The foundation of the whole credential. Staffing firms can be liable for discriminatory practices in recruiting, assigning and removing workers, including when a client requests the discriminatory treatment.
- Protected categories and how they apply to job orders
- What to do when a client makes a discriminatory request
- How discrimination law intersects with screening and interviewing
Domain 2: Application and interview practices
What you may and may not ask, record and rely on when taking applications and conducting interviews.
- Lawful versus unlawful interview questions
- Application content and documentation habits
- Consistency in how candidates are treated
Domain 3: Contracts
Agreements with clients and with temporary workers define who is responsible for what.
- Key terms in client service agreements
- Worker-facing agreements and acknowledgments
- How contract language allocates risk
Domain 4: Employer/employment definitions
Who counts as the employer, and what counts as employment, drives nearly every other legal question in staffing.
- Distinguishing employees from other worker classifications
- Why the definitions matter for taxes, benefits and liability
Domain 5: Screening and selection of temporary workers
The operational side of choosing workers: verification, background-related practices and selection criteria applied fairly.
- Applying screening standards consistently
- Documenting selection decisions
Domain 6: Laws unique to temporary services work
Rules that apply because of the staffing model itself, rather than to employers generally.
- Obligations specific to placing workers with client companies
- Where staffing-specific rules diverge from general employment practice
Domain 7: Family leave
How leave obligations apply when workers are placed on assignment and employment is tied to a staffing firm and a client.
- Leave eligibility and the staffing relationship
- Handling leave requests during an assignment
Domain 8: ADA
Disability-related obligations, including accommodation questions that arise when the worker's job site belongs to someone else.
- Reasonable accommodation in a placement setting
- Responsibilities of the staffing firm versus the client
Domain 9: Drug testing
When and how testing can be required, applied and documented without creating legal exposure.
- Policy design and consistent application
- Coordinating testing expectations with clients
Domain 10: Joint employer
The doctrine that can make both the staffing firm and the client responsible for the same worker.
- Factors that create joint-employer exposure
- How control over the worker affects liability
One structural detail worth knowing: the FAQ supports the first six topics, while the manual description adds the last four and overlaps on discrimination and contracts. Those overlapping items appear once in the list above, which is why the count is ten rather than twelve.
Key Takeaway
Because no weighted blueprint exists, do not skip any of the ten areas on the assumption that it will be lightly tested. Build a baseline across all ten, then spend extra time on the topics where case-based scenarios are most likely to blend several rules at once, such as joint employer, ADA and discrimination.
Registration, Fees and Retests
Registration is a bundled price. It includes the legal manual, the examination and the certificate. The difference between member and nonmember pricing is large enough that it is worth weighing before you register.
| Item | NAPS Member | Nonmember |
|---|---|---|
| Registration (manual, exam, certificate) | $300 | $600 |
| Retest | $150 | $300 |
| Annual renewal fee | $35 (individuals at member firms) | $50 |
All amounts are in US dollars. The full picture, including how membership costs factor in, is covered in our CTS certification cost breakdown. If you are weighing the outlay against career benefits, the ROI analysis walks through the decision.
Because the manual and exam are updated annually, and the public descriptions do not identify a specific current manual edition, you should confirm you are working from the version included with your registration rather than relying on older copies passed around the industry.
Eligibility: What Is Clear and What Is Not
Some requirements are plainly stated. There is no length-of-service requirement, and NAPS membership is not required. Candidates must accept NAPS ethical standards and program rules.
The less tidy part is who may sit for the exam. The current CTS page extends access to HR professionals and hiring managers. The Certification Program Rules page, however, still describes a requirement to be a currently employed, full-time owner, partner, manager or employee in the temporary-service business. These two descriptions do not line up neatly.
Keeping the Credential Current
Earning the certificate is the first step, not the last. To maintain it you must complete 20 contact hours (2.0 CEUs) each year, and at least 17 of those hours must be NAPS-approved content. You also pay an annual renewal fee of $35 for individuals at member firms or $50 for nonmembers, due on the anniversary of your examination date.
That anniversary-based timing is easy to overlook. Mark the date when you pass so that your continuing-education hours and fee are ready by the same date each year. Since the manual and exam are revised annually, the ongoing education requirement also keeps holders in touch with changes to the legal landscape they are certified in. Exam scheduling specifics are covered in the CTS exam dates guide.
Sequencing Your Preparation
Study methods are not what separates candidates on this exam; sequencing is. The ten topics build on each other, so the order in which you cover them matters. A sensible approach is to anchor early weeks on the definitions and discrimination framework, then layer on the specialized statutes.
Foundations: Domains 4 and 1
- Employer/employment definitions come first because every later topic depends on who the employer is
- Laws of discrimination, since it recurs through interviewing, screening and contracts
Daily practice: Domains 2 and 5
- Application and interview practices
- Screening and selection of temporary workers
Structure: Domains 3 and 6
- Contracts with clients and workers
- Laws unique to temporary services work
Specialized statutes: Domains 7, 8 and 9
- Family leave, ADA and drug testing
Integration: Domain 10, then full review
- Joint employer, which pulls together control, contracts and liability
- Timed scenario practice across all ten topics
For a complete study approach, read the CTS study guide, and keep the CTS cheat sheet handy for last-minute review. When you are ready to test your recall under realistic conditions, try the practice tests on our main site, and consider building a routine around CTS training resources.
Separating This CTS from Others
"CTS" is a crowded acronym. Several unrelated credentials share it, and each has its own certifying body, fees, schedule and content. None of that applies here. When you evaluate information about this credential, check that it names the National Association of Personnel Services and the temporary-staffing subject matter, and discard anything that does not. The same caution applies to forum posts and older articles that mix details from different programs.
If you want a clean reference set, our pages on what CTS is, CTS meaning and CTS certification keep the focus on this specific credential. You can also return to the main practice site to see how our question sets map to the ten topics above.
