A professional certification can help job seekers demonstrate skills, meet hiring requirements and stand out in competitive fields, but only when the credential is recognized by employers and connected to a real career goal.
Credentials can be especially useful for people changing careers, returning to work, seeking promotions or trying to prove expertise without a new degree. They can signal that a candidate has mastered a defined body of knowledge, met an industry standard or completed a required assessment.
The U.S. Bureau of Labor Statistics defines certifications as credentials issued by nongovernmental organizations that demonstrate a person has the skills or knowledge needed to perform a particular job. Occupational licenses, by contrast, are issued by government agencies and provide legal authority to work in certain professions.
The distinction matters because a certification can strengthen a résumé, while a license may be legally required to perform a job. An aspiring project manager may benefit from a recognized professional certification; a nurse, electrician, teacher, real-estate agent or cosmetologist may need a license before legally practicing in a state.
The strongest evidence suggests that credentials are associated with better labor-market outcomes, though they do not automatically cause higher pay or guarantee a job. BLS research found that full-time wage and salary workers with an active certification or license earned median weekly wages 35% higher than workers without one in 2018. Workers with credentials also had lower unemployment rates and higher labor-force participation.
Those figures should be interpreted carefully. People who hold credentials may also have more education, experience, employer support or access to higher-paying occupations. The credential itself is not necessarily the sole reason for the earnings difference.
Still, the practical lesson is clear: the right certification can give an employer more evidence that a candidate is prepared to do a specific job.
What a professional certification is
A professional certification is usually awarded by an industry association, professional body, vendor, nonprofit organization or other nongovernmental institution.
It typically requires some combination of:
- Training or coursework.
- A formal examination.
- Work experience.
- A skills assessment.
- Continuing education.
- Agreement to an ethical or professional code.
- Renewal after a set period.
For example, an IT professional might earn a cybersecurity, cloud-computing or networking certification. A project manager might pursue a credential from the Project Management Institute. A financial professional might seek a specialized planning or accounting designation. A health-care worker may earn a certification in a clinical specialty.
CareerOneStop, a U.S. Department of Labor-sponsored career resource, describes certification as an award that shows a person has specific skills or knowledge in an occupation, industry or technology.
A certificate is not always the same thing.
A certificate often shows that someone completed a course, program or training workshop. A certification generally shows that someone met an external standard, often through an examination or professional assessment. A license is granted by a government agency and may be mandatory for legal practice in a regulated occupation.
| Credential type | Who issues it | What it usually shows | Example |
|---|---|---|---|
| Certificate | School, college, training provider or employer | Completion of training or coursework | Digital marketing course certificate |
| Certification | Industry association, vendor or professional body | Verified skills or knowledge against a standard | Cloud, project-management or cybersecurity certification |
| License | State or local government agency | Legal authority to practice an occupation | Nursing, teaching, electrical or real-estate license |
| Degree | College or university | Broad academic study in a field | Associate’s, bachelor’s or master’s degree |
Before paying for a program, job seekers should confirm which type of credential they are pursuing. The name alone can be misleading.
How certifications help in a job search
The immediate value of a certification is signaling.
Hiring managers often must evaluate many résumés quickly. A recognized credential can help them identify candidates who have completed training, passed an exam or met a professional standard.
This is especially useful when a candidate lacks a traditional career history in the field.
A former teacher moving into corporate training, for example, may use instructional-design or project-management credentials to show that their skills translate beyond the classroom. A customer-service worker moving into IT may use an entry-level technical certification to demonstrate that they have studied the field seriously. A marketer may use analytics or advertising-platform certification to verify familiarity with commonly used tools.
Certifications can help in five main ways:
1. They meet employer requirements
Some job listings explicitly require a certification or license. In these cases, the credential is not an advantage; it is an entry condition.
BLS data show that licensing and certification are especially common in health care, legal work, education, training and library occupations.
If a role requires a credential, applicants without it may be screened out automatically.
2. They make skills easier to verify
A résumé can say “proficient in cloud computing” or “experienced in data analysis.” A certification gives the claim more weight, especially when the issuer is known in the industry.
3. They can help career changers
A career changer may not have years of direct experience. A recognized certification can provide a bridge by showing recent, relevant learning and a commitment to the new field.
4. They may strengthen promotion cases
Employees can use certifications to demonstrate readiness for more complex work, leadership responsibilities or technical specialization. Some employers tie pay increases, bonuses or job classifications to credential attainment.
5. They build professional confidence and networks
Many credentials require continuing education, membership in a professional association or participation in events. These can create access to mentors, job leads and industry knowledge.
The value is not just the line on the résumé. It is the knowledge, proof of effort and professional connections that can come with it.
Credentials and earnings: What the data says
BLS data consistently show an association between certifications or licenses and stronger employment outcomes.
In 2018, full-time wage and salary workers with a certification or license had median weekly earnings of $1,106, compared with $818 for workers without one, a difference of 35%.
The same research found that workers with credentials were more likely to be in the labor force and had lower unemployment rates.
More recent BLS annual averages show that 23.9% of wage and salary workers held a certification or license in 2025. The share was higher in government employment, where 37.7% of wage and salary workers held one, compared with 21.6% in private industries.
The key caution is causation.
Workers with credentials may earn more because they are in occupations that require licensing or because they have higher levels of education and experience. A surgeon, lawyer or licensed engineer is likely to earn more than a worker without a credential, but the license itself is only one part of a much longer training pathway.
The correct conclusion is not that any certification produces a 35% pay raise.
The more realistic conclusion is that recognized credentials are common in fields with established professional standards and can be associated with stronger employment prospects.
Before enrolling, ask whether the credential is required, preferred or ignored in the job market you want to enter.
Choose the credential employers actually value
The biggest mistake job seekers make is collecting certifications without checking whether employers care about them.
The internet is full of fast, inexpensive credentials that promise career transformation. Some are useful. Others have little recognition outside the company that sells them.
A credential is most valuable when it is:
- Required by law or regulation.
- Listed in job descriptions.
- Recognized by major employers in the industry.
- Issued by a respected professional body.
- Current and regularly updated.
- Connected to a real skill assessment.
- Supported by employer tuition assistance or reimbursement.
- Relevant to the job level you are seeking.
CareerOneStop’s Certification Finder allows users to search national certifications by occupation, industry, organization or keyword. Its database includes more than 6,300 certifications, giving job seekers a way to compare options before spending money.
A practical research process looks like this:
- Search 20 to 30 job listings for the role you want.
- Note every required or preferred certification.
- Count which credentials appear most often.
- Look at the seniority level of jobs requesting them.
- Ask professionals in the field whether the credential is respected.
- Check total cost, exam requirements and renewal obligations.
- Compare the credential against other ways to build proof of skill, such as a portfolio or apprenticeship.
The credential with the best marketing may not be the one with the best career value.
High-value fields for certification
Certifications can be useful in many industries, but their impact varies.
Information technology and cybersecurity
IT certifications are often used to validate familiarity with specific platforms, cloud environments, networking systems or security practices. They can be especially useful for entry-level job seekers without computer-science degrees, though hands-on projects and experience remain important.
Examples include cloud, networking, security, data and vendor-specific credentials.
Health care
Licenses and certifications are central in health care. Many roles require state licenses, while clinical specialties may require additional certifications. The stakes are high because credentials protect patient safety and establish legal authority to practice.
Project management
Project-management credentials can help professionals in construction, technology, health care, business operations and nonprofit work. Their value tends to increase with work experience because employers want evidence that a candidate can manage real projects, not only pass an exam.
Finance and accounting
Professional designations can be important in accounting, financial planning, insurance, auditing and investment roles. These fields often have strict ethical, regulatory and continuing-education requirements.
Skilled trades
Electricians, HVAC technicians, welders, mechanics and construction professionals often need licenses, apprenticeships or industry certifications. In these fields, credentials can be directly tied to job eligibility and pay progression.
Education and training
Teaching licenses are often required in public schools. Certifications can also help trainers, instructional designers, educators and administrators demonstrate specialized knowledge.
Marketing, design and business tools
Vendor certifications in analytics, advertising platforms, customer-relationship management and digital marketing can be useful, especially for early-career professionals. Their value is strongest when paired with a portfolio showing that the person can apply the tool to real campaigns or business problems.
Certification alone is not enough
A credential is evidence. It is not a substitute for experience.
Employers still want examples of work, strong communication, reliability, problem-solving and an ability to collaborate. A certification may help a candidate receive an interview, but it does not guarantee an offer.
The strongest job-search strategy combines certification with proof of application.
For example:
- A data analyst can pair a certification with a portfolio of dashboards and projects.
- A cybersecurity candidate can document home labs, vulnerability assessments or supervised projects.
- A marketing candidate can show campaign plans, content samples and analytics results.
- A project-management candidate can describe a volunteer or workplace initiative they planned and delivered.
- A cloud-computing candidate can publish a small technical project and explain the architecture.
The formula is:
Credential + Portfolio + Experience + Networking=Stronger candidacy
No part is sufficient on its own. Together, they make an employer’s decision easier.
Put certifications to work on your résumé
A certification should appear in several places, not only in a separate list at the bottom of a résumé.
On the résumé
Include the credential’s full name, issuing organization and date earned. If it is in progress, state the expected completion date honestly.
Example:
Certified Associate in Project Management, Project Management Institute, Expected – December 2026.
Do not write “certified” before passing the exam.
In the summary
If the certification is central to the role, include it near the top.
Example:
Entry-level cybersecurity analyst with Security+ certification, hands-on network-lab experience and a background in customer support.
In the cover letter
Explain how the training connects to the employer’s needs.
On LinkedIn
Add it under licenses and certifications, include the credential ID if appropriate, and post a concise explanation of the project or skill you developed while earning it.
In interviews
Be prepared to answer: “What did you learn?” and “How would you apply it here?”
Hiring managers are more impressed by a candidate who can explain how the credential changed their approach to work than by someone who simply lists an acronym.
Avoid costly credential mistakes
Professional credentials can be expensive.
Costs may include tuition, study materials, exam fees, practice tests, application fees, membership dues, travel, renewal charges and required continuing education.
Before committing, calculate the total cost:
Total credential cost = Training + Exam + Materials + Renewal + Lost work time
Then compare it with the expected benefit.
Ask:
- Is this certification required or preferred for jobs I want?
- How many relevant job listings mention it?
- Can my employer pay or reimburse the cost?
- Is the certification portable if I change employers?
- Does it expire?
- Are continuing education credits required?
- Is there an apprenticeship or degree alternative?
- Could a portfolio demonstrate the same skill more cheaply?
Beware of programs that promise guaranteed jobs, unusually high salaries or immediate placement without credible evidence. Legitimate certification bodies provide clear information about requirements, exams, renewal and professional standards.
The Department of Labor’s credential guidance stresses the difference between industry-recognized credentials, certificates and other forms of completion.
A high-quality credential should be transparent about what it proves, and what it does not.
Use free resources before paying
Job seekers do not need to navigate the credential market alone.
CareerOneStop’s Certification Finder can help identify recognized credentials by occupation and industry.
State workforce agencies, community colleges, public libraries, unions, professional associations and nonprofit workforce programs may provide low-cost training, exam preparation or vouchers.
Veterans can also use Department of Labor Career and Credential Exploration materials through the Transition Assistance Program, which offers tools for assessing careers, credentials and training pathways.
Before paying out of pocket, ask:
- Does your current employer offer tuition reimbursement?
- Does a workforce-development program cover exam fees?
- Does a professional association offer scholarships?
- Can a community college provide the same preparation at lower cost?
- Is there a free vendor training path for entry-level content?
- Can you take the exam first and pay for advanced training only if needed?
The best credential strategy is targeted, not expensive by default.
The bottom line
Professional certifications can help candidates get better jobs when they are relevant, recognized and combined with practical evidence of skill.
They can open doors for career changers, strengthen promotion cases, meet licensing or employer requirements and give hiring managers a faster way to assess job readiness.
But they are not magic.
A certification that no employer recognizes is unlikely to help. A credential without applied skills may not survive an interview. And a costly program is not worthwhile if it does not improve access to the kind of work you actually want.
The smartest approach is to start with the job, not the credential. Study employer requirements, talk to people in the field, compare options and choose the certification that proves a skill the market values.
When used strategically, a certification can turn learning into evidence — and evidence into opportunity.
FAQs
Do professional certifications really help you get a job?
They can, especially when employers list them as required or preferred. Certifications help demonstrate specific skills, meet eligibility requirements and make a résumé easier to evaluate. BLS research has found that workers with certifications or licenses are associated with higher earnings and lower unemployment, though the credential may not be the only reason for those outcomes.
What is the difference between a certificate, certification and license?
A certificate typically shows you completed a course or training program. A certification is usually issued by a nongovernmental body and verifies skills or knowledge against a standard. A license is issued by a government agency and provides legal authority to work in a regulated occupation.
Which certifications are most valuable?
The most valuable certification is the one requested by employers in your target field. Check job postings, ask people already working in the industry and use CareerOneStop’s Certification Finder to identify recognized options.
Will a certification increase my salary?
It may, but there is no automatic pay increase. BLS found that workers with a certification or license had median weekly earnings 35% higher than workers without one in 2018. However, the difference also reflects occupation, education, experience and the fact that some higher-paying jobs require credentials.
Can I get a job with a certification and no degree?
In some fields, yes. IT, cybersecurity, skilled trades, customer-support technology, digital marketing and some health-care support roles may value certifications alongside portfolios, apprenticeships or practical experience. Other professions, including many licensed fields, require degrees in addition to certifications or licenses.
How do I know whether a certification is legitimate?
Look for a respected issuer, transparent exam requirements, clear renewal rules, employer recognition and an independent skills assessment. Avoid programs promising guaranteed employment or unusually high income without evidence. Review job listings and ask professionals in the field before enrolling.
Should I list an in-progress certification on my résumé?
Yes, if you state it accurately. Include the credential name, issuing organization and expected completion date. Do not describe yourself as certified until you have met all requirements and passed the relevant exam.
Where can I find certifications for my career?
CareerOneStop’s Certification Finder is an official U.S. government-supported resource that lets users search national certifications by occupation, industry, organization or keyword. It includes more than 6,300 certifications.
