Accreditations are formal recognitions that a school, program, organization, or business meets established quality standards set by an independent evaluating body. You encounter them most often in education (where they determine whether a degree is worth the paper it’s printed on) and in industries like healthcare and manufacturing (where they signal that an organization follows best practices). Understanding how accreditation works helps you make better decisions about where to study, which credentials to pursue, and which organizations to trust.
How Accreditation Works
At its core, accreditation is a peer-review process. An outside organization, called an accrediting agency, sets quality standards and then evaluates whether an institution or program meets them. The process typically involves a self-study (where the organization being evaluated documents how it meets each standard), a site visit by a team of reviewers, and a final decision by the accrediting body. Accreditation is not permanent. Organizations must undergo periodic reviews, usually every few years, to maintain their status.
The key distinction that separates accreditation from other quality markers is that it evaluates the organization or program itself, not individual people. A college gets accredited. A hospital gets accredited. An individual person, by contrast, gets licensed or certified.
Accreditation in Higher Education
Education is where accreditation matters most to everyday decision-making. The U.S. Department of Education recognizes two basic types: institutional accreditation and programmatic (sometimes called specialized) accreditation.
Institutional accreditation applies to an entire college or university. It means the school as a whole, including its faculty, facilities, finances, and governance, meets baseline quality standards. Regional and national accrediting agencies handle this level of review. If a school lacks recognized institutional accreditation, its degrees may not be accepted by employers or other colleges, and its students typically cannot receive federal financial aid.
Programmatic accreditation applies to a specific department, school, or curriculum within a larger institution. A university might be institutionally accredited while also holding separate programmatic accreditation for its nursing school, engineering program, or business college. Some programmatic accreditors also evaluate freestanding professional schools and even training programs housed in non-educational settings like hospitals. In fields like nursing, law, and engineering, graduating from a program with the right programmatic accreditation can be a prerequisite for sitting for licensing exams or being admitted to graduate school.
The practical takeaway: before enrolling in any college or program, check both levels. A school can be institutionally accredited but have an unaccredited program in the specific field you care about, which could limit your career options after graduation.
Accreditation vs. Certification vs. Licensure
These three terms get mixed up constantly, but they serve different purposes and carry different legal weight.
- Accreditation evaluates organizations and programs. It is technically voluntary, though in practice it can be essential. A hospital that skips accreditation, for example, may be unable to bill Medicaid. A nursing program without accreditation may find that graduate schools refuse to admit its alumni.
- Certification evaluates individuals. It recognizes that a person has demonstrated knowledge or skills beyond what’s legally required. Think of a certified public accountant (CPA) or a project management professional (PMP). Certification is typically granted by a professional association, not a government body.
- Licensure is a legal requirement. It’s granted by a state government and gives an individual permission to practice a profession. A registered nurse must hold a state license to work. Licensure aims to protect the public by verifying that practitioners meet minimum safety standards. You cannot legally practice without it in licensed professions.
The simplest way to remember the difference: accreditation is for institutions, certification is a voluntary credential for individuals, and licensure is a mandatory legal permission for individuals.
Accreditation Outside of Education
Accreditation extends well beyond colleges. In healthcare, Joint Commission International (JCI) accreditation is widely regarded as the gold standard for hospitals and medical centers worldwide. Earning JCI’s Gold Seal of Approval signals that a facility meets rigorous patient safety and quality-of-care standards, and organizations must demonstrate continuous performance improvement to maintain it.
In business and manufacturing, ISO (International Organization for Standardization) certifications function similarly. An ISO 9001 designation, for instance, signals that a company’s quality management systems meet international standards. While technically called “certification” in ISO’s framework, the process mirrors accreditation: an independent body audits the organization against established criteria.
Business schools seek AACSB accreditation to distinguish their programs. Only a fraction of business schools worldwide hold this designation, which evaluates curriculum quality, faculty qualifications, and student outcomes. For students comparing MBA programs, AACSB accreditation is one of the most reliable quality signals available.
Who Oversees the Accreditors
In U.S. higher education, the accreditors themselves are held accountable by two bodies. The U.S. Department of Education is required by law to publish a list of nationally recognized accrediting agencies that the Secretary of Education determines to be reliable authorities on educational quality. The Department reviews these agencies to ensure they effectively enforce their standards. The Council for Higher Education Accreditation (CHEA) provides a second layer of independent oversight.
The Department of Education maintains a searchable Database of Accredited Postsecondary Institutions and Programs, where you can verify whether a school or program holds recognized accreditation. This is the single most reliable way to check a school’s legitimacy before enrolling or accepting a degree from a job applicant.
How to Spot Fake Accreditation
Diploma mills, schools that sell degrees with little or no academic work, frequently claim to be “accredited” by agencies they invented. The names often sound official and authoritative, which makes them hard to distinguish at a glance. According to the Federal Trade Commission, if you cannot find the accrediting agency on the Department of Education’s recognized list, treat the claim with serious skepticism.
Several red flags point to a diploma mill rather than a legitimately accredited institution:
- Tuition charged per degree rather than per credit hour, course, or semester
- Few or no degree requirements, or heavy emphasis on awarding degrees for “life experience”
- Degrees earned in unusually short timeframes, or multiple degrees listed for the same year
- Names that mimic well-known universities but are located in a different state or country
- A school that is brand new or has recently changed its name
When reviewing someone’s educational background (or choosing a school for yourself), verify accreditation directly through the Department of Education’s database rather than trusting what a school’s own website claims. A few minutes of checking can save years of wasted tuition or the embarrassment of holding a worthless credential.
Why Accreditation Matters for You
If you’re choosing a college, accreditation determines whether your credits will transfer to another school, whether you can receive federal student loans and grants, and whether employers and graduate programs will recognize your degree. In some fields, graduating from an unaccredited program means you cannot sit for required licensing exams at all.
If you’re hiring, verifying a candidate’s accreditation claims protects your organization from credential fraud. If you’re a patient choosing a hospital, accreditation status is one of the clearest indicators of whether a facility meets recognized safety and quality benchmarks. And if you’re evaluating a business partner or vendor, industry accreditations like ISO standards offer third-party verification that the organization operates at a professional level. In every context, accreditation serves the same basic function: an independent authority has reviewed the organization and confirmed it meets the standards it claims to meet.
