If you've studied outside the US and are applying to a US university, employer, or licensing board, you may be asked to get your transcript "evaluated" before anyone will look at your GPA. This isn't bureaucratic busywork — it's because the institution reading your application usually has no in-house expertise in how your specific country's grading and degree system works, and a credential evaluation service exists to translate it into terms they can act on.
What Credential Evaluation Services Do — and Why They Exist
A credential evaluation service reviews your academic transcripts and degree certificates from a non-US institution and produces a report stating the US equivalency of your qualification — typically your degree's US equivalent (e.g., "equivalent to a Bachelor of Science degree from a regionally accredited US institution") and, often, a converted GPA on the 4.0 scale.
These services exist because a US university's admissions office, an employer's HR department, or a state licensing board can't realistically maintain expertise in the grading conventions, degree structures, and accreditation standards of every education system in the world. Rather than each of them separately trying to interpret a transcript from an unfamiliar system, they outsource that judgment to organizations that specialize in exactly this.
The Major Evaluators
The most commonly requested evaluators in US higher education contexts are:
| Evaluator | Notes |
|---|---|
| WES (World Education Services) | One of the largest and most widely recognized; commonly required by US graduate programs and increasingly by employers and immigration processes |
| ECE (Educational Credential Evaluators) | Also widely accepted; a common alternative to WES, sometimes specifically required or preferred by certain universities |
| Scholaro | Used by some universities, particularly for a quicker or lower-cost evaluation, though acceptance is less universal than WES/ECE |
| Other NACES-member agencies | Several other evaluators (SpanTran, Josef Silny & Associates, and others) are members of NACES — the National Association of Credential Evaluation Services — and are accepted by many institutions |
Always check which evaluator your specific university requires or accepts before paying for one. Some universities name WES or ECE explicitly and will not accept a report from another agency; others accept any NACES-member evaluation. Submitting the wrong evaluator's report can mean paying for a second evaluation.
Document-by-Document vs. Course-by-Course Evaluation
Evaluators typically offer at least two report types, and which one you need depends entirely on the purpose:
| Evaluation Type | What It Provides | Common Use |
|---|---|---|
| Document-by-document | Confirms your degree(s) and their US equivalency, without a course-level GPA breakdown | Often sufficient for immigration purposes, some employers, or general degree verification |
| Course-by-course | Evaluates every individual course and grade, produces a converted GPA and course-by-course US credit equivalency | Usually required for university admissions, since admissions committees want a GPA and a sense of your specific coursework |
Applying to a university's graduate program almost always requires the course-by-course version — check the specific program's requirements page rather than assuming.
The Process, Step by Step
- Create an account and select your evaluation type with your chosen evaluator (WES, ECE, etc.), specifying the purpose (education, immigration, employment).
- Submit your documents. This typically means official transcripts and degree certificates. Requirements vary — some evaluators require documents sent directly from your issuing institution, others accept documents you submit yourself if they're sealed/official, and some now support electronic submission through partnerships with universities.
- Institutional verification. Evaluators generally verify your credentials directly with your issuing institution — confirming your enrollment, grades, and degree conferral with the university's registrar rather than relying solely on the documents you provide. This step is often the longest part of the timeline, particularly for institutions the evaluator hasn't processed before or those without established digital verification channels.
- Evaluation and report generation. Once documents are verified, the evaluator applies its own conversion methodology to produce your report — including your converted GPA if you selected course-by-course.
- Delivery. Reports are typically sent electronically to you and/or directly to the institutions or organizations you designate, depending on the service used.
Cost and Processing Time (Approximate — Verify Current Figures)
Fees and turnaround change periodically, so treat these as rough, non-binding ranges rather than current pricing — always check the evaluator's own website before budgeting or planning your application timeline:
- Cost: Course-by-course evaluations have historically run roughly in the $150-$250 USD range, with document-by-document evaluations somewhat cheaper; expedited processing typically costs extra.
- Processing time: Standard processing has commonly been cited in the range of one to several weeks after all required documents are received and verified — but delays are common if your institution is slow to respond to verification requests, so applicants are generally advised to start the process well ahead of application deadlines (often recommended: at least 6-8 weeks of buffer).
Because both figures shift and vary by evaluator, document type, and your country of origin, confirm current cost and turnaround directly on the evaluator's website before relying on any number you read elsewhere, including this one.
When It's Required vs. Optional
This varies significantly by university and by purpose:
- Some universities require a formal credential evaluation (often specifying WES or ECE by name) as a mandatory part of the application for all applicants with non-US transcripts.
- Some universities accept raw transcripts and perform their own internal review using in-house international admissions staff, treating a formal evaluation as optional or only necessary in ambiguous cases.
- Some purposes outside university admissions — certain employers, professional licensing boards, and immigration processes — have their own separate requirements, which may specify a particular evaluator or evaluation type distinct from what a university requires.
Never assume — check the specific requirement listed on your target university's international admissions page, since "credential evaluation required" and "transcript accepted as-is" are both common depending on the institution.
How This Connects to Your GPA
This is the part applicants often miss: if your target university requires a credential evaluation, the GPA on that evaluator's report is very often the number that actually gets used in your application review — not whatever you calculate yourself using a generic conversion table. For a deeper look at why percentage-to-GPA conversion varies so much and how to estimate your own GPA in the meantime, see our guide on converting a percentage or other scale to US GPA.
Common Mistakes
- Ordering the wrong evaluation type (document-by-document when course-by-course was required, or vice versa) and having to pay again.
- Using an evaluator the university doesn't accept. Always confirm WES vs. ECE vs. "any NACES member" before paying.
- Starting too close to the deadline. Institutional verification delays are common and largely outside your control.
- Assuming the evaluation is only about your degree title. For admissions purposes, the GPA conversion is usually the more consequential part of the report.
- Not sending the report to every institution that needs it. Evaluators typically require you to specify recipients (or order additional copies) — a report sitting in your own account isn't automatically visible to your universities.
