Certifications and Micro-Credentials

By Brian Tr · Updated Oct 7, 2026

"Credential" is one of the loosest words in learning. A course completion PDF, a professional exam pass, a LinkedIn badge and a government licence all get called credentials, and vendors often use "certificate", "certification" and "micro-credential" as if they were interchangeable. They aren't. They differ in who issues them, what was assessed, whether they expire and who will accept them.

For an EdTech company, the difference decides what you can honestly sell. For an L&D buyer, it decides whether the thing your employees earned means anything outside your own LMS. This article lays out the definitions, the two standards that matter most (ISO/IEC 17024 for certification bodies and Open Badges for digital credentials), the size of the credential market, and what makes a credential worth having. If you want the university angle, see micro-credentials and certificates in higher education. This piece is about the definitions and the corporate learning market.

Key Facts

• Credential Engine's 2025 count found 1,850,034 unique credentials in the United States, offered by 134,491 providers, up from 1,076,358 in its 2022 count (Credential Engine, Counting Credentials 2025).
• Of those, 1,022,028 were badges and 486,352 were certificates, while only 6,892 were certifications and 3,384 were micro-credentials (Credential Engine, 2025).
• The Council of the European Union adopted its Recommendation on micro-credentials on 16 June 2022. It defines a micro-credential as the record of learning outcomes acquired after a small volume of learning, assessed against transparent criteria (Council of the EU, 2022).
• Open Badges 3.0 became publicly available on 29 May 2024 and is designed as a W3C Verifiable Credential (1EdTech).
• Credential Engine's rule of thumb: certificates typically require courses and don't expire, while certifications require a test and typically expire (Credential Engine, 2025).

Certificate vs certification

The cleanest distinction comes from the people who count credentials for a living. Credential Engine describes certifications as credentials that represent competency in the skills needed for an occupation or profession. It says certificates typically require courses and typically don't expire, while certifications require a test and typically expire. A certification, in its words, is awarded by an authoritative body, such as an industry or professional association, to an individual who demonstrates designated knowledge, skills and abilities in a particular occupation (Credential Engine, 2025).

Put in practical terms:

Two other categories sit nearby. An occupational licence is government-backed permission to practice a profession, and Credential Engine separates it from a certification on exactly that point: a certification can help you get a job, a licence lets you legally do the work (Credential Engine, 2025). A degree is a long-form academic award. Neither is the subject here, but both are useful for seeing where certificates and certifications sit in the range.

The practical risk is labeling. A course provider that calls its completion document a "certification" is borrowing the authority of a different kind of credential. Buyers and learners who ask "who assessed me, against what, and who stands behind it?" can usually sort the two quickly.

ISO/IEC 17024: what sits behind a real certification

Professional certification has its own international standard. ISO/IEC 17024, "Conformity assessment: General requirements for bodies operating certification of persons", sets the criteria for the organizations that certify individuals. Accreditation bodies assess certification bodies against it. The International Accreditation Service describes it as a structured and impartial framework for certifying individuals, and says accreditation verifies that a certification body operates in line with the standard (IAS).

You don't need to read the standard to understand the logic. Public guidance from the National Institute of Building Sciences, written for certification bodies, shows what the standard asks them to document:

• A defensible exam. The body has to document how the assessment method corresponds to the competence requirements, along with the fairness, validity and reliability of the examination process, citing clauses 9.2 and 9.3 of the standard (NIBS guidance).
• Impartiality. Offering training and certification in the same legal entity is treated as a threat to impartiality, so a certification body that also trains must identify those threats and show how it minimizes them (clause 5.2.3.a) (NIBS guidance).
• Appeals and maintenance. The appeals policy should cover adverse decisions such as denial of eligibility and denial of recertification, which tells you eligibility rules and recertification are part of the scheme, not extras (NIBS guidance).

The training-versus-certification point matters for EdTech. A company that sells exam prep and also runs the exam sits inside a conflict the standard is designed to manage. Whether a given credential is accredited under ISO/IEC 17024 is a fact to check with the issuer, and it is a strong signal when the answer is yes. But accreditation is not required for a credential to be useful, and not every respected credential has it.

Micro-credentials: two official definitions

Micro-credentials are the newest and least settled category. Credential Engine itself notes that the open definition of micro-credentials means there is no universal agreement on what the credential type indicates (Credential Engine, 2025). Two bodies have tried to fix that.

The Council of the EU, June 2022

The Council Recommendation on a European approach to micro-credentials for lifelong learning and employability, adopted on 16 June 2022, defines a micro-credential as the record of the learning outcomes that a learner has acquired following a small volume of learning. Those outcomes are assessed against transparent and clearly defined criteria. The definition adds that micro-credentials are owned by the learner, can be shared, are portable, may be stand-alone or combined into larger credentials, and are underpinned by quality assurance (Council of the EU, 2022).

The Recommendation also lists standard elements to describe one. The mandatory ones are:

• identification of the learner
• title of the micro-credential
• country or region of the issuer
• awarding body
• date of issuing
• learning outcomes
• notional workload (in ECTS credits where possible)
• level of the learning experience, where applicable
• type of assessment
• form of participation in the learning activity
• type of quality assurance behind it

Optional elements include prerequisites, supervision and identity verification during assessment, grade achieved and stackability options (Council of the EU, 2022). It's a useful checklist even if you're nowhere near Europe: if a credential can't tell you who assessed what, how, and at what workload, it is not describing itself well.

UNESCO, 2022

UNESCO published "Towards a common definition of micro-credentials" in 2022, proposing a definition reached through a consensus process by a global expert panel (UNESCO UNEVOC). UNESCO's TVET glossary summarizes it as a record of focused learning achievement verifying what the learner knows, understands or can do, with assessment against defined standards, awarded by a trusted provider (UNESCO UNEVOC glossary). The glossary page publishes only a short extract, so read the full document if you need the exact wording.

The two definitions agree on the important parts: a small unit of learning, a real assessment against stated standards, and an issuer that people can trust. Neither says micro-credentials replace degrees. Both say they can stand alone or combine into something larger.

Stackability has limits

Stacking is the idea that small credentials add up. The Council Recommendation is careful here: stackability means the possibility, where relevant, of combining credentials that build logically on each other, and the decision to stack lies with the receiving organization, such as a school or employer. Stacking does not create an automatic entitlement to a qualification or a degree (Council of the EU, 2022). So "stackable" in a marketing line is a design intention, not a guarantee. Ask which institution will recognize the stack and in what way.

Digital badges and the Open Badges standard

A digital badge is a credential in image-plus-data form: a picture that links to machine-readable information about who earned it, from whom, and for what. The dominant open format is Open Badges, maintained by 1EdTech.

Version 3.0 was released to the public on 29 May 2024 after approval by the 1EdTech community. It is designed as a W3C Verifiable Credential, which 1EdTech says makes badges more tamper-proof and trustworthy. Issuers can embed the criteria the badge was assessed against, evidence of skill, the issue date and a verifiable reference to the recipient. The release notes also say badges can be aligned with skills frameworks, including academic and industry-recognized standards (1EdTech).

Why does this matter commercially? A badge that only exists as a PNG on a learner's profile is a claim. A badge that carries verifiable data can be checked by an employer without calling the issuer, moved between wallets and platforms, and linked to evidence. That is where badges stop being decoration and start working as credentials.

Badges can still be hollow. A badge for watching a video is easy to produce at scale (see the market numbers below). The standard says how a badge is packaged and verified. It says nothing about whether the thing behind it was worth earning.

Industry certifications as a category

Vendor and industry certifications are a major part of the corporate learning market, and they follow the pattern above. Cloud and software vendors such as AWS, Google and Microsoft run role-based certification programs for their own platforms. Professional associations run certifications that aren't tied to a product, for fields such as project management or human resources. In both cases a third party, or the vendor itself acting as the standard-setter, defines competencies and examines candidates.

Three features explain why employers pay attention to them:

1. The standard is public and the exam is separate from the course. Learners can prepare in many ways, and the exam is the proof.
2. Expiry forces currency. Certifications typically expire, as noted above, which ties the credential to current practice and gives the holder a reason to renew.
3. Recognition can accumulate. When employers name a certification in job posts, it becomes easy for hiring managers to read. That is something to check for each credential, not assume.

Vendor certifications also carry a caveat. They certify skill on that vendor's platform, and the vendor has a commercial interest in the program growing. They are real signals for roles that use the platform. They are weaker evidence of general skill.

How big is the credential market?

Credential Engine's 2025 count is the most complete public census of US credentials, and its numbers are worth reading slowly. It found 1,850,034 unique credentials from 134,491 providers, with total annual expenditures of $2.34 trillion across the ecosystem, public and private sectors and individuals combined. The 2022 count was 1,076,358, so the total rose by 773,676 (Credential Engine, 2025).

Source: Credential Engine, Counting Credentials 2025. Secondary school diplomas (52,948 in 2025) are omitted from the table. Counts are of distinct credentials offered, not of people who hold them.

Three things stand out. First, badges and certificates make up most of the total, and certifications are a tiny slice, which is consistent with certifications being demanding and tied to standard-setting bodies. Second, the certification count slipped slightly between reports while badges more than doubled, so growth is in the low-barrier end of the range. Third, the report's category structure changed between editions (the 2025 report uses new categories that combine similar credentials regardless of provider), so comparing one edition to the next calls for the report's own 2022 reclassified figures, as in the table.

One caution for anyone quoting these numbers: the count says how many credentials exist, not how many are valued by employers. A million badges tells you about supply.

What makes a credential valuable

No single measure settles it, but four questions do most of the work.

1. How rigorous is the assessment? The strongest credentials test performance against a stated standard, with an exam or practical assessment the candidate can fail. Both the Council Recommendation and the UNESCO definition put assessment against clear criteria at the center. A credential given for attendance is a different thing.

2. Who issues it, and what is their reputation? An independent body with no stake in selling you the course is easier to trust. ISO/IEC 17024's impartiality requirements exist for this reason. For vendor credentials, the question is whether the issuer's standard is respected beyond its own customers.

3. Do employers recognize it? A credential has value in a labor market only to the extent that hiring managers read it as a signal. That is an empirical question to test, with job posts and with your own hiring managers, not something to assume from a vendor's claims.

4. Can it be verified? Can a third party confirm it is real, current and the holder's, without a phone call? This is where Open Badges 3.0 and verifiable credentials help, and where expiry dates, public registries and recertification records matter.

A short test for any credential you're considering buying, building or listing on a resume: Who assessed the learner, against what standard, and how would a stranger check? If the answer is "nobody, nothing and they couldn't", it's a certificate of participation, whatever the label says.

The business angle for EdTech companies

Credentials are a product decision, not just a feature. A few things follow from the definitions above. These points are analysis, not research findings.

A credential can raise the perceived value of a course, but only if it is credible. A learner deciding between two similar courses may prefer the one ending in a recognized exam or a verifiable badge. If the credential is easy to get and nobody recognizes it, it adds little and can damage trust in the rest of the catalog.

A credential gives learners a reason to finish. The assessment at the end is a goal, which may help with the completion problem described in course completion rates. The evidence on this is mixed, so test it on your own learners rather than assuming it.

The business model changes depending on where you sit.

• Course providers (the typical marketplace seller) mostly issue completion certificates and badges. That is the low-friction end, and it is where platforms such as those in course marketplaces compete.
• Certification bodies earn from exam fees, renewals and sometimes membership, and are expected to keep training separate for impartiality.
• Training companies that prepare people for outside exams sell the course while a third party sells the exam. That separation is healthy.
• Employers and internal academies issue credentials mainly for internal mobility and compliance, which links to how they buy and measure training.

For the wider range of ways learning companies charge, see corporate training business models.

Don't confuse credential volume with outcomes. Issuing more badges isn't evidence that anyone learned anything. If you sell credentials to companies, expect buyers to ask what the assessment was and whether it predicts job performance, the kind of question covered in proving training ROI. A credential tied to a defined skills framework, as discussed in skills-based learning, is easier to defend than one that stands alone.
