Between 2014 and 2023, large US employers removed degree requirements from a growing number of job ads. Researchers at Harvard Business School and the Burning Glass Institute then checked who actually got hired. Across 11,300 roles, the share of hires without a bachelor’s degree rose by only about 3.5 percentage points on average after a company dropped the requirement.

Employers said one thing and did another. That gap sits at the centre of the professional certification vs degree debate. It’s also why advice like “skills matter more than diplomas” can cost you real money.

The truth is more specific. For some jobs, a certificate plus proof of your work is enough. For others, a degree is the only way in, and no certificate will open that door. Below, I compare four types of credential and test them against three careers: a digital marketer, a software professional and a healthcare professional.

Professional certification vs degree is really a four-way choice

Most articles set two things against each other. In practice there are four, and mixing them up is how people buy the wrong thing.

• Academic qualification. A degree or diploma from a university or college. It shows you completed a programme of study.
• Professional certification. A credential from an industry body or a company, such as a project management association or a cloud provider. It’s voluntary and usually tests a specific set of skills.
• Occupational license. Legal permission to practise. In the US, the Bureau of Labor Statistics separates the two by who issues them: licenses come from a government body, certifications from non-government ones.
• Informal evidence. A portfolio, work samples, a GitHub profile, references, a track record. No awarding body, but often the first thing a hiring manager looks at.

“Credential” is the umbrella word for all four. “Qualification” usually means the formal academic kind. “License” means the law says you need it. That’s credential vs qualification vs license in a paragraph. The difference between certification and license is simple: one is optional proof of skill, the other is permission to work.

Why companies dropped degree requirements, and why hiring barely moved

Employers gave sensible reasons for dropping degree requirements. Degrees can screen out capable people, shrink the hiring pool and favour candidates whose families could afford college. But when the Harvard and Burning Glass team looked at actual hiring, only 37% of firms changed outcomes in a meaningful way. About 45% changed the wording of their job ads and little else.

Why? A degree is a cheap shortcut. A recruiter with 400 applications can filter by degree in seconds. Judging skills takes work tests, structured interviews and managers willing to back a stranger. Until a company builds that process, deleting the requirement changes the ad, not the shortlist.

For you, this means the professional certification vs degree question is partly a question about the employer. A company that runs practical tests will care about what you can do. One that still screens by degree may never read your certificate.

So can certifications replace a degree? Sometimes, in unregulated jobs, when paired with proof. Never on their own in regulated ones, as the healthcare example below shows.

Digital marketing: proof beats paperwork

Can you work in digital marketing without a degree? Yes. Nobody needs a license to run ads or manage email campaigns, so employers can hire whoever they trust.

Vendor certifications from platforms like Google or Meta show you know the tools. Entry-level programmes such as the Google Data Analytics Professional Certificate teach useful vocabulary and basic methods. But they’re easy to collect, so they rarely separate one candidate from another. A small campaign you ran, with the budget, the result and what you’d change, does that far better.

Degrees still matter in some places, especially large companies with graduate schemes. For most marketers, the sensible mix in the professional certification vs degree choice is a certificate to learn fast and a portfolio to prove it.

Software: a degree isn’t required, but it’s common

Do software engineers need a computer science degree? Not legally. But look at the numbers. In Stack Overflow’s 2024 developer survey, about 46% of professional developers held a bachelor’s degree and 28% a master’s, while around 5% had secondary school as their highest level. Most developers have a degree, and a real minority don’t.

Is a certificate better than a degree for tech? Not better, different. A cloud or security certification shows you can work with a specific platform. A computer science degree shows you’ve studied the fundamentals, like how algorithms and systems behave. A platform-heavy role may reward the first. A general engineering role often wants the second, or years of equivalent experience. Developers without degrees who get hired usually have shipped work to point to.

International job seekers face one more catch. Immigration rules can turn a degree from a preference into a requirement. In the US, for example, the H-1B visa for specialty occupations generally calls for a bachelor’s degree or equivalent in a related field. Check the current rules for your target country before assuming experience will count.

Healthcare: where the debate mostly ends

Here the professional certification vs degree debate mostly ends. Regulated professions have qualification requirements written into law, and employers can’t waive them.

What is an occupational license? It’s legal permission, granted by a government agency or regulator, to do certain work or use a protected title. In the US, states set the rules, so healthcare occupational licensing requirements differ depending on where you plan to work. In the UK, doctors must register with the General Medical Council and hold a license to practise, and nurses must register with the Nursing and Midwifery Council. Nurses trained overseas also sit the NMC’s Test of Competence. Across the EU, a directive on recognising professional qualifications covers regulated professions.

Can an employer hire an unlicensed professional? Into a role the law reserves for licensed people, generally no. Employers in these fields typically check the public register before hiring, and the worker can face penalties too.

A certificate can’t replace the degree here, because only approved programmes lead to registration. Extra certifications, such as advanced life support training, help candidates who are already licensed. They don’t get anyone through the door.

Moving countries changes the rules

The professional certification vs degree question looks different once you cross a border. International recognition of professional qualifications runs on two tracks. Academic recognition asks whether your degree counts for further study. Professional recognition asks whether you can practise. Different bodies decide each one.

The OECD’s Pathways to Professions report shows how inconsistent the labels are. Nursing programmes are classed as academic in England and professional in parts of Belgium, for example. In non-regulated occupations, there’s usually no authority at all, so the employer decides what a foreign qualification is worth.

Practical checks by region:

• UK: regulators must publish their entry requirements, and the government runs a Regulated Professions Register.
• EU: member states keep lists of regulated professions, and recognition rules apply mainly to those.
• Canada: regulated professions are overseen by provincial and territorial regulators, so check the one where you plan to work.
• US: licensing mostly sits with individual states.

How to decide on professional certification vs degree for your own job

1. Check if the job is regulated. Search your country’s regulator or regulated professions register. If it is, find the approved route and stop comparing.
2. Read ten current job ads for the role you want, in the country you want. Count how many require a degree and how many name a specific certification.
3. Check the awarding body. Ask who issues the certificate, whether it’s accredited, and whether it’s recognised where you plan to work. Judge the issuer, not the course marketing.
4. Look for stackable credentials. In higher education, these are short credentials designed to add up, sometimes into a diploma or degree. Ask in writing whether the credits transfer. It lets you start cheap and keep your options open.
5. Build proof alongside. Whatever you choose, produce something an employer can see.

On pay, be careful with any professional certificate vs bachelor degree salary comparison. People who earn certificates and people who earn degrees differ in age, experience and field, so averages rarely compare like with like. Look up pay for your exact job title in your country’s official statistics instead.

A job ad is a wish list. A regulator’s rule is a legal wall. Most of the confusion around professional certification vs degree comes from treating the two as the same thing. Before you pay for anything, find three people doing the job you want, in the country you want, and ask what they had to hold to get hired. Ten minutes of that beats ten hours of comparison articles.

FAQ

Is professional certification vs degree really an either-or choice?

Usually not. Many people hold a degree and add certifications later, and some use short certificates as a first step toward a degree. In regulated professions it isn’t a choice at all, because the license route decides.

Can certifications replace a degree?

In unregulated fields like marketing or parts of tech, they can, if you also show real work. In regulated professions such as medicine and nursing, they can’t.

Do employers prefer certifications or degrees?

It depends on the role and the employer. For most unregulated jobs, professional certification vs degree matters less than evidence you can do the work. Employers that still filter by degree will do so before they read your certificates.

What is the difference between certification and license?

A certification is voluntary proof of skill, issued by a non-government body. A license is legal permission to work, issued by a government body or regulator.

Can an employer hire an unlicensed professional?

Not into a regulated role where the law requires a license. In unregulated jobs, there’s nothing to license, so employers can hire on skills and experience.

Do employers verify certifications?

They can, and for regulated roles they usually do by checking the public register. Many awarding bodies also offer online verification. Checks on informal course certificates are less common.

Are online course certificates recognised?

It depends on the issuer. A certificate from a university or recognised industry body carries more weight than a simple completion badge. Pair it with a project and check whether the provider is accredited.
