A grading system translation is a certified translation that reproduces your original grades exactly and translates the issuing institution’s grading legend alongside them. It does not convert your marks into another country’s GPA or letter-grade scale. That job belongs to a credential evaluator, not a translator.

Three names come up constantly once you start this process: NAATI, which certifies the translators authorised to produce documents Australian authorities accept; ISEP, whose Transcript Evaluation Guidelines set out what a compliant transcript should contain; and WES, one of the credential evaluators that performs grade conversion once a literal translation exists.

A compliant grading system translation must show:

  • Your original grades, unchanged
  • The institution’s grade-scale legend, translated
  • Credit units and dates as they appear on the source document
  • A signed translator’s declaration certifying accuracy

Key Takeaways

A compliant grading system translation preserves every original grade and reproduces the institution’s grading legend, with the translator never converting marks into another country’s scale.

Point Details
Definition matters A grading system translation preserves original grades and legend; it never converts to a different scale.
Checklist before ordering Confirm original grades, translated legend, credit units, dates and a translator’s declaration are all included.
Missing legend protocol If no legend exists, the translator documents its absence rather than guessing at equivalencies.
Fraud risk is real Requesting grade conversion or improvement is treated as academic fraud by evaluators like WES.
Certitranslate’s role Certitranslate’s NAATI-certified translators preserve grades and legends exactly, with a signed declaration for official use.

Translating grading systems: what a certified transcript translation must include

Universities, visa officers and credential evaluators are all reading the same document for different reasons, so a certified transcript translation has to satisfy all three at once. Miss one element and the whole submission can bounce back.

At minimum, the translation should contain:

  • Every grade exactly as it appears on the original, letter for letter and number for number
  • A translated version of the institution’s own grade-scale legend, not a generic explanation you found online
  • Credit units or ECTS values, matched precisely to the source document
  • Dates, semester or academic year labels, and registration periods
  • The institution’s name, any official seal, and stamps reproduced or clearly referenced
  • The same layout as the original, course by course, year by year
  • A translator’s declaration with signature, credential number and date

Each item exists because someone downstream relies on it. Admissions staff cross-check the seal against the original. Employers want dates that line up with a resume. Evaluators like WES need the legend to run their own equivalency process, and if you study certified translations more broadly, you’ll notice the same pattern: nothing gets summarised, everything gets matched.

On file format, a clear, high-resolution scan or PDF of the original is the safest starting point. Blurry photos of transcripts are one of the most common reasons a translator has to chase a client for a second copy before work can even start.

Pro Tip: Send the transcript and any separate grading-scale bulletin together in one file. Translators working from a transcript alone often can’t confirm the legend’s exact wording, which slows everything down.

How should a translator render and annotate a grading scale?

Good translators follow a small set of rules that keep a transcript legally and academically trustworthy. None of them involve interpreting what a grade “really means” in another country’s system.

  • Reproduce grades literally. An 88, a 14/20, a B+, they get carried across exactly. No rounding, no relabelling.
  • Translate the legend verbatim. If the source transcript defines “Distinction” as 75 to 84 out of 100, that definition gets translated word for word, not paraphrased into a rough Australian equivalent.
  • Keep the legend attached and in order. It travels as a companion page or an attached translated page, in the same sequence as the original, so nobody has to hunt for it.
  • Bracket unusual terms on first use. A course name or grading term with no direct English equivalent gets bracketed in the source language the first time it appears.
  • Preserve credit values exactly. ECTS points, contact hours, whatever unit the institution used, stays as written.

If the transcript arrives with no legend at all, the translator documents that absence formally rather than guessing at what the scale might mean, a point Victoria’s international education guidance makes explicit. The client is then advised to request an official legend from the registrar.

Here’s roughly what that looks like on the page:

Original: 88/100
Translated legend: “Distinction: 75–100. Awarded for work demonstrating comprehensive understanding of course material.”
Translator’s note: Grade-scale legend supplied by [Institution Name] Academic Transcript Handbook, 2023 edition.

Pro Tip: Ask your translator to keep the row-per-course structure intact rather than summarising a busy transcript into a tidy table. Evaluators read consolidated tables as a warning sign, not a convenience.

This division of labour, precise translation on one side, interpretation on the other, is what academic translation best practice actually means in day-to-day work, and it’s the same logic evaluators rely on when they assess functional equivalence between grading systems.

Why asking for grade conversion can get your application rejected

Some applicants ask a translator to “just convert it to a GPA” or make a grade “look a bit better” for admissions. Don’t. Guidance from Victoria’s education department is blunt on this point: translators must not convert or improve grades, and doing so is treated as academic fraud.

Evaluators like WES watch for specific red flags:

  • A translated grade that doesn’t match the pattern of grades around it
  • A GPA or percentage appearing where the original document used a completely different scale
  • Course consolidation that hides individual results
  • A missing legend with no translator’s note explaining why

Evaluator-facing guidance is direct about the consequence: translated documents that summarise or convert grades instead of preserving them get rejected outright, and repeated manipulation can lead to a permanent flag on file.

The safer path is always the same: supply the originals, request a literal translation, and let the evaluator or admissions office run any conversion themselves.

How to brief your translator so nothing gets lost

A good brief saves a week of back-and-forth. Before you order, gather:

  • A high-resolution scan or PDF of the full transcript
  • Any separate grading bulletin, handbook page or legend document
  • Certified copies if your recipient specifically requires them
  • The purpose of the translation (visa, university admission, employer verification)
  • Any formatting instructions from the recipient, including whether they want a sealed envelope or a direct upload

Then work through this order:

  1. Confirm file format and resolution before sending (PDF is generally preferred over photos)
  2. State the purpose clearly so the translator can format the declaration correctly
  3. Flag whether the recipient needs a physical sealed copy or accepts digital submission
  4. Ask for a translator’s note if you know the legend is missing or incomplete
  5. Review the draft against the original line by line before it’s finalised

You can copy this brief almost word for word when you place your order:

“Please preserve all original grades exactly as they appear and include a translated version of the institution’s grading-scale legend. If no legend is available on the transcript, add a translator’s note documenting its absence. Do not convert or interpret grades into another grading system.”

What does a NAATI-certified translation need to satisfy recipients?

A NAATI-certified translation carries specific, recognisable elements: a translator’s declaration attesting to accuracy, a signature, the translator’s credential number, the language pair, and the date and scope of certification. NAATI’s own application guidance specifies preferred file formats and upload size limits, and recommends English translations be completed by a NAATI-certified translator wherever possible.

Recipients generally expect:

  • A PDF version, since most portals and visa systems process this format cleanly
  • Correct file sizing to meet upload limits without compressing text into illegibility
  • Clarity on whether originals need to accompany the translation physically or digitally

For overseas qualification assessments specifically, NAATI requires both the qualification document and the academic transcript in English. The translator’s role stops at accurate, literal rendering; any equivalency assessment happens afterward, on the evaluator’s side.

Three grading systems, presented the right way

Different countries structure grades differently, but the presentation rule never changes: show the original, translate the legend, add a note if needed.

A 0–100 percentage system: original mark “88/100” stays as is, alongside a translated legend entry defining what that band means at the issuing institution, with no GPA attached.

A 1–20 or 0–20 scale: the number stays numeric, and the translator explains the institution’s own definition of a passing or distinction-level result, not a generic international standard.

A weighted letter-grade system: letters and any weighting notation carry across unchanged, with no attempt to map them onto a four-point GPA scale.

  • Original numbers and letters never change
  • Institutional definitions travel with the grade
  • No scale gets mapped onto another country’s system

What a NAATI-certified translation provider actually checks for

Every completed transcript translation goes through a second review by a native-language checker before certification, and any missing grading legend gets flagged and documented rather than quietly filled in. Turnaround runs faster when clients supply a clean, complete scan up front, since chasing a second copy is what usually adds days to a job. Consistency between the declaration, the seal reproduction and the original layout is what separates a document that sails through review from one sent back for correction.
