WES iGPA, and Where GradeKiln Stands
Half the grade-conversion queries on the internet are really questions about WES. Here is what the iGPA is, when you need it, and what this site's numbers are and are not.
What WES actually does
World Education Services is a credential evaluator: you send verified transcripts, it converts each course through its own country tables into US terms and issues an evaluation - including the iGPA, a 4.0-scale GPA - that admissions offices, licensing boards and immigration processes formally accept. That acceptance is the product. No free calculator produces it, including this one, and most of the long tail of "WES calculator" pages are other sites reverse-engineering tables WES has never published.
What GradeKiln's numbers are
Working equivalences, computed in your browser, with the method printed next to the result: each scale's best grade and pass line anchored, your grade placed proportionally between them, the position replayed into the target scale - the modified Bavarian formula's logic, generalized. Every scale page cites the instrument it implements. What our numbers are not is an evaluation anyone accepts, and the converter says so on its face. In this field that sentence is rarer than it should be.
The practical sequencing
Estimate first, evaluate when named. Shortlisting programs, sanity-checking an agent's promise, deciding whether an application is worth the fee - that is estimate territory, free and instant. The moment a checklist names WES or another evaluator, that body's process is the only one that counts, and no converter substitutes for it. If a requirement just says "4.0-scale GPA" with no named evaluator, ask the institution who may compute it before paying anyone.
WES is not the only evaluator
It is the most requested, but it is one of roughly twenty members of NACES, and a different member reading the same transcript can return a different GPA. That is not a mistake by either of them, and applicants discover it at the worst possible moment. WES vs ECE sets out why the numbers diverge and what to check before you pay anyone.
Questions this page gets asked
Is GradeKiln's conversion the same as a WES evaluation?
No, and it does not try to be. WES produces a credential evaluation that admissions offices formally accept; GradeKiln produces an instant working equivalence with its method printed beside the number. Use GradeKiln to understand where you stand, and the evaluator your institution names when the application requires one.
How does WES calculate the iGPA?
Course by course: each grade on your transcript is converted through WES's own country table into US letter grades, then combined into a 4.0-scale GPA weighted by credit. The tables are WES's own and are not published as open data, which is one reason third-party 'WES calculators' can only approximate it.
Do universities accept GradeKiln conversions?
No - and no honest converter site should claim otherwise. Institutions accept evaluations from the bodies they name (WES, ECE and others). What a good estimate gives you is earlier, free information for shortlisting and planning.
When do I actually need a WES evaluation?
When the institution, licensing body or immigration process names WES (or a similar evaluator) as a requirement. If the requirement just says 'GPA on a 4.0 scale', ask who is allowed to compute it before paying anyone.
Why do GradeKiln's numbers sometimes differ from WES's?
Different methods, honestly labelled: WES applies its own per-country tables course by course; GradeKiln anchors each scale's best grade and pass line and interpolates - the modified Bavarian logic German universities publish. Mid-scale grades in compressed systems (the Netherlands, France) are where the two diverge most.
