US Credential Evaluation Guide: WES vs ECE, NACES, and Which Report You Need
If you earned your degree outside the United States and need it recognized — for a job, graduate school, or a professional license — you'll likely need a credential evaluation: a formal statement of what your foreign education equals in the US system. The landscape is confusing because no single government agency does this. Here's how it actually works: what NACES is, how WES and ECE differ, and the one rule that decides everything.
There is no government evaluator — the receiving institution decides
Unlike Canada's IRCC-designated list, the US has no federal list of approved evaluators. Instead, the organization receiving your application decides which evaluations it accepts: the university you're applying to, the employer hiring you, or the state licensing board. Always check their published list first. An evaluation from a provider they don't recognize is wasted money.
What NACES actually is
NACES — the National Association of Credential Evaluation Services — is a membership association, not an evaluation company. Founded in 1987, it sets professional standards for evaluation practice, and its members agree to follow them. Many US universities and licensing boards require evaluations from a NACES member because membership signals vetted expertise, ethical practices, and qualified staff.
Key point: NACES membership is not a guarantee of acceptance. A university may list WES specifically; a licensing board may publish its own separate list. NACES gets you in the door with most institutions — it doesn't override their published preferences.
WES vs ECE: the two giants
| WES (World Education Services) | ECE (Educational Credential Evaluators) | |
|---|---|---|
| Type | Non-profit, founded 1974 (NYC + Toronto) | Non-profit, founded 1980 (Milwaukee) |
| NACES | Founding member (1987) | Charter member (1987) |
| Course-by-course | ~$186 Basic / ~$239 ICAP | ~$195 |
| Document-level report | ~$118 Basic / ~$171 ICAP | ~$100 (General) |
| Typical speed | ~2 weeks verification + 1–2 weeks evaluation | ~5 business days after documents received; rush available (~$80 extra) |
| Canada immigration | Yes — IRCC-designated for ECAs | No — cannot be used for Express Entry ECA |
| Strengths | Largest evaluator; US + Canada coverage; IRCC designation | Faster turnaround; country-by-country document rules (sometimes accepts applicant-submitted copies) |
WES raised prices ~3% on January 1, 2026 — confirm live pricing before paying. Both are non-profits; neither is a government agency.
Other NACES members include SpanTran (The Evaluation Company), IERF (International Education Research Foundation), Josef Silny & Associates, and about 20 more. The US Department of State also recognizes AICE (Association of International Credential Evaluators) as a membership body.
Which report for which purpose
- Graduate school admissions: almost always course-by-course — admissions offices need your converted GPA on a 4.0 scale. Check whether the school names a preferred provider (many list WES specifically).
- Professional licensing (nursing, teaching, engineering, etc.): the licensing board's list controls. Some boards accept any NACES member; others name specific providers. ECE explicitly produces reports for internationally educated nurses accepted by many US state boards. Never assume — read the board's published requirements.
- Employment: employers vary wildly. Large employers often accept any NACES member; some specify WES. A document-level (general) report usually suffices unless the job posting says otherwise.
- US immigration: credential evaluation is rarely the mechanism — US immigration categories generally don't use ECAs the way Canada does. (For Canadian immigration, you need an IRCC-designated ECA — ECE doesn't qualify; use WES or another designated org.)
- Canadian purposes from the US: if you later apply to Canada, get the Canadian product (ECA for IRCC), not the US report.
The process and common failures
The process mirrors Canada's: create an account, pay (non-refundable), have documents sent per the provider's country-specific requirements, wait for verification and evaluation. Where it fails:
- Wrong provider for the receiver. The #1 failure — a perfect ECE report is useless to a university that only lists WES.
- Wrong report type. A document-level report won't satisfy a graduate program that needs a GPA.
- Applicant-sent documents where institution delivery is required. ECE is somewhat more flexible here (country-by-country rules sometimes allow applicant-submitted certified copies); WES generally requires institution-to-agency delivery.
- Translations. Non-English documents need certified translations, same as Canada.
- Assuming US and Canadian reports are interchangeable. They're different products for different systems.
Frequently asked questions
Is WES better than ECE?
Neither is objectively better — they're differently positioned. WES is larger, covers both the US and Canada, and holds the IRCC designation. ECE is typically faster and sometimes more flexible on document submission. The right choice is whichever your receiving institution accepts, at the speed and price you prefer.
What does NACES membership guarantee?
That the evaluator meets NACES professional standards. It does not guarantee any specific university, employer, or board will accept the report — their published lists are what matter.
Can I use my US evaluation for Canadian immigration?
No. Canadian Express Entry requires an ECA from an IRCC-designated organization in the IRCC format. A US course-by-course report doesn't qualify — and ECE isn't designated at all.
How long does US credential evaluation take?
After documents are accepted: roughly 1–3 weeks at WES, about 5 business days at ECE for standard service. The document-gathering stage (getting your institution to send records) is usually the longest part, same as in Canada.
Do I need an evaluation for every degree?
Generally have your highest completed credential evaluated; graduate programs may want the full history. Check the receiver's requirements — some want every post-secondary credential, others only the highest.
