Not every "online university" is what it claims to be, and the format itself makes it easier for illegitimate programs to look convincing — a polished website and a fast application process don't tell you anything about whether the degree will actually be recognized by employers, other universities, or licensing boards. Accreditation is the mechanism that separates a real degree from a worthless one, and it's worth understanding before you commit money or years to any online program.
Regional Accreditation: The Recognized Standard in the US
In the United States, regional accreditation (increasingly referred to under a unified national umbrella following a shift away from strict geographic regions, but still commonly called "regional" accreditation) is the standard held by the vast majority of established public and private nonprofit universities — the institutions most employers, other universities, and licensing boards recognize as credible without a second thought. Georgia Tech, UT Austin, UIUC, UC Berkeley, University of Michigan, and essentially every well-known university you'd recognize by name carry this type of accreditation, whether for their on-campus or online programs.
National accreditation, by contrast, is a separate accreditation category that has historically been used by a large share of vocational, religious, and for-profit institutions. It is a real, federally recognized form of accreditation in a narrow technical sense — but it is generally regarded as a lower bar, and credits or degrees from nationally accredited institutions are often not accepted for transfer, further graduate study, or by employers who specifically expect a regionally accredited credential. This distinction matters a great deal in practice: a school leaning on "we're accredited" without specifying which type can be using national accreditation as a way to sound legitimate while sidestepping the much higher standard that regional accreditation represents. If a program's marketing mentions accreditation but doesn't clearly name a specific, checkable accrediting body, treat that as a reason to dig further, not reassurance.
How to Check Accreditation Status
Don't take a school's word for its own accreditation — verify it independently:
| Where You're Checking | How to Verify |
|---|---|
| United States | Search the US Department of Education's database of accredited institutions or the Council for Higher Education Accreditation (CHEA) database. Both let you look up an institution and see exactly which body accredits it and at what level. |
| Outside the US | Check the relevant national accreditation or quality-assurance body for that country — most countries maintain an official register of recognized universities and degree-granting authority (for example, a national ministry of education's list of recognized institutions). |
| A specific program, not just the institution | Some fields (business, engineering, nursing) also have their own programmatic accreditation on top of institutional accreditation — for example, AACSB for business schools. Check whether the specific program carries relevant programmatic accreditation if your field has one, since institutional accreditation alone doesn't guarantee it. |
The key habit: look the accrediting body up independently, and confirm that the accreditor itself is recognized (by the US Department of Education, CHEA, or the equivalent body in another country) — not just that the school claims to have "an accreditor."
Diploma Mill Red Flags
A diploma mill is an operation that sells degrees with little or no real academic requirement behind them. These have gotten more sophisticated over time, but the warning signs are fairly consistent:
- No real admissions process. Legitimate programs — even less selective online ones — require transcripts, some form of application, and a genuine review. If you can "enroll" with just a credit card and no academic review at all, that's a serious red flag.
- Instant or unusually fast degree completion. A legitimate Master's degree takes real coursework time — typically at minimum close to a year even in accelerated formats. Offers of a degree in a matter of weeks, or based primarily on "life experience" credit, are a classic diploma mill pattern.
- Unusually low cost, even relative to legitimate low-cost programs. Georgia Tech's OMSCS at roughly $7,000-$10,000 total is already an outlier on the low end for a real accredited degree — a program charging a few hundred dollars for a full Master's degree is not offering the same thing, regardless of what it's called.
- No accreditation, or accreditation from an unrecognized body. Some diploma mills invent their own "accrediting agency" or use one that sounds official but isn't recognized by any government or established accreditation council. Always verify the accreditor independently rather than trusting a name that sounds legitimate.
- Aggressive marketing promising guaranteed high-paying jobs. Real universities don't typically guarantee employment outcomes as part of their sales pitch, because they can't — outcomes depend on the individual, the market, and the field. Heavy, high-pressure marketing focused on income promises rather than academic content is a consistent warning sign.
A Simple Checklist Before You Apply
- Confirm the specific accrediting body by name, and verify it independently through the US Department of Education or CHEA database (or the equivalent outside the US).
- Confirm whether the degree is the same credential as the institution's on-campus program, or a separately branded "online degree" — this affects both quality and how it's perceived later (see our guide on whether an online degree is worth it for more on this).
- Check that admissions involves a real review — transcripts, some form of application, and genuine selection criteria.
- Sanity-check the cost and timeline against known legitimate programs — extremely low cost combined with extremely fast completion is the classic combination to watch for.
- Search for the school's name alongside terms like "accreditation" or "diploma mill" to see whether it's been flagged publicly, since scrutiny of shady programs tends to surface in higher education press and forums over time.
Taking twenty minutes to verify accreditation independently is a small amount of diligence against the risk of spending significant money and time on a credential that won't be recognized where it matters.
