Q Grader

A Q Grader is a person who has passed a formal exam proving they can taste and grade coffee to a published standard — and can do it consistently, matching other trained graders rather than just having good personal taste. If cupping is the method and the 100-point score is the output, the Q Grader licence is the quality control on the human doing it.

The licence is deliberately a licence, not a diploma: it expires. A Q Grader has to be re-tested every three years, because a palate drifts.

What the exam looks like now

The Specialty Coffee Association currently runs and issues the licence. Its official course page states that the licence “is awarded to individuals who successfully complete the Q Grader course and all required assessments,” and describes the credential as “proof of a coffee professional’s ability to evaluate, describe, and communicate coffee quality using internationally recognized standards” (SCA — Q Grader, accessed 2026-07-23).

The shape of it:

  • Six consecutive days. Instruction and testing in sensory evaluation, cupping, and green coffee grading.
  • Nine assessments — eight practical evaluations plus one written exam. You must pass all of them.
  • Two attempts each, taken during the course. SCA’s page adds that from 2026 onward a third attempt becomes available on individual practical exams.
  • Valid for three years, then renewed.
  • Not a beginner course. Candidates are expected to arrive already experienced in cupping and sensory analysis, already familiar with the Coffee Value Assessment, and with “a high level of sensory skill.”

That last point matters for anyone reading this as a career path: the Q course tests a palate you built somewhere else. It does not build one for you.

The whole thing is now anchored to the Coffee Value Assessment (CVA) — the SCA’s newer evaluation framework, which asks a grader to judge a coffee across its physical quality, its flavour and aroma, its overall cup quality, and its origin characteristics, rather than producing one number from one form.

Where it came from

The programme was built to solve a coordination problem, not a training one. Before it existed, “this coffee is an 88” meant whatever the person saying it meant. CQI’s stated purpose for Q grading is to create a “skilled and credible body” of graders — people whose scores can be compared to each other. The value is in the comparability, not in any individual’s expertise.

It has been running roughly two decades: CQI’s own FAQ page refers to certifying Q Graders “for the past 20 years” (accessed 2026-07-23). The exact starting year is where the sources fall apart.

To verify — the founding year, and the purpose quote

Secondary sources disagree on when Q grading began: Tastify says the standardisation was created in 2003, while MTPak Coffee says the programme was first established in 2004 (both cited via the research report, accessed 2026-07-23). Neither is a primary CQI source, and no CQI or SCA page read here states a founding year at all — CQI’s own wording is only the round “past 20 years.” Do not state a founding year as fact until a dated CQI record confirms one. Note also that 2004 is the year of the SCA cupping form CQI says it still uses, which is an easy thing for a secondary writer to have confused with the programme’s start. The “skilled and credible body” phrasing above is attributed to CQI’s Q Grading Rules and Regulations v4.5 (April 2020); that PDF was retrieved but not machine-readable, so the exact wording is unconfirmed and the document may predate the current programme.

Who owns the licence — the unresolved part

For most of its life the Q Grader programme belonged to the Coffee Quality Institute (CQI), the nonprofit that built it, and that history is why the two names are used almost interchangeably in the trade. CQI’s own site still carries a “Q Certification” section and still sells Q coffee evaluation.

But the SCA now describes itself as the issuer, and CQI’s website carries a link whose address reads cqi-sca-transition — so something formally moved. See the callout below; the wiki does not yet have the primary document that says exactly what.

One thing is settled, though, and it is the part a working grader actually cares about: a certificate already issued is not void. CQI’s own Q Grader FAQ page states that the changes “ha[ve] no impact on your Q Grader Certification, which is still valid and still signifies that you have the skills of a professional cupper” (CQI — FAQs regarding Q Grader certification, accessed 2026-07-23). Whatever the paperwork between the two bodies says, nobody’s licence was cancelled by it.

To verify — who issues the Q Grader licence, and when it changed

The SCA’s live course page presents the Q Grader licence as SCA-issued and makes no mention of CQI (SCA — Q Grader, accessed 2026-07-23). CQI’s site, meanwhile, still lists Q Certification and links to a page whose URL slug is cqi-sca-transition — but that page returned 404 and CQI’s general FAQ page contains nothing about a transition (both accessed 2026-07-23).

A second CQI page pulls the other way. CQI’s Q Grader FAQ states plainly that “Coffee Quality Institute (CQI) will continue to train, test, and certify Q Graders as it has done for the past 20 years,” and that “CQI will continue to use the 2004 cupping form in its Quality Evaluation program offerings, including the Q Grader course, for the foreseeable future” (accessed 2026-07-23). That page is undated, and its framing — defending the older cupping form against the SCA’s newer Coffee Value Assessment — suggests it was written before whatever handover the cqi-sca-transition slug points at. But taken at face value, CQI claims to still be the certifying body while SCA claims to be the issuer.

So: the effective date, what exactly transferred, and whether two separate Q courses now exist are all unconfirmed here. This also bears on the ownership question already flagged in Coffee Quality Institute — treat both as open until a dated CQI or SCA announcement is read directly.

Renewing: calibration

A Q Grader who lets the licence lapse stops being one. Three years is the confirmed lifespan, and both bodies say so in their own words: SCA states the licence is “valid for 3 years,” and CQI’s exams page states a certificate is “valid for thirty-six (36) months” — for the original certification and for every renewal after it (both accessed 2026-07-23).

Renewal is by calibration, not by repeating the course. SCA is explicit that “retaking the full six-day course is not required for renewal.” CQI’s exams page describes the mechanism: “a certified Q Grader meets for an in-person calibration course every third year.” It is a shorter, supervised re-test that checks your palate still lines up with everyone else’s.

The re-test is graded on flights — sets of coffees cupped together. CQI’s page requires “passing at least two of the three flights” (CQI — Q Grader exams and calibrations, accessed 2026-07-23). So a calibration is not all-or-nothing on every cup: you are allowed to miss one flight of three and still hold the licence.

That design tells you what the credential is actually measuring. It is not asking whether you are a gifted taster on your best day — it is asking whether you are reliably inside the tolerance band, repeatedly, years apart.

To verify — the numeric calibration threshold

The research report cites CQI’s Quality Evaluation Program Guidebook (v6, January 2023) for a specific pass mark: that a renewing Q Grader must score 86 or higher and report defects accurately in two of three cupping sessions. The “two of three” part matches CQI’s live exams page, which confirms it as flights. The 86 figure does not appear on any CQI or SCA page read here, and the guidebook PDF was retrieved but its text was not machine-readable (accessed 2026-07-23). Treat 86 as a reported number tied to a specific guidebook version, not as a standing rule. Source: CQI — QE Program Guidebook v6 (PDF).

To verify — the calibration and recertification rules

CQI’s Quality Evaluation Program Guidebook (v8, May 2024) is cited as setting a 12-month calibration window — opening six months before the certificate expires and closing six months after — and allowing a lapsed grader to sit a Q Recertification Course for up to five years past expiry, after which they must retake the full course. The guidebook PDF was retrieved but its text could not be read machine-side, and these rules describe the CQI-era programme; whether they survive under SCA administration is unknown. Source: CQI — QE Program Guidebook v8 (accessed 2026-07-23).

Arabica and robusta are separate licences

Grading the two species is not the same job, and the programme splits accordingly: a Q Arabica Grader is licensed on arabica, a Q Robusta Grader (often written R Grader) on robusta, working to the Fine Robusta standards CQI developed. Arabica grading follows Specialty Coffee Association standards; robusta grading follows CQI’s own.

Licensed graders are also the workforce behind CQI’s Q Coffee system, where a producer submits a lot, certified graders score it blind, and the lot comes back with a standardised score and report that a buyer on the other side of the world can act on without tasting it first.

Why it matters

The licence is the reason a number travels. When a lot scores 90 at origin, the buyer in Tokyo or Berlin is trusting that the person who wrote that number was tested against the same standard as everyone else — that is the entire economic function of the credential. It underwrites the score sheets at Best of Panama and Cup of Excellence, and it is what lets green coffee be bought at a distance.

It also concentrates geographically in a telling way. Roughly half the world’s Q Graders are in Japan, South Korea, and China (per Coffee Intelligence, accessed 2026-07-22) — the same markets that dominate record auction bidding, which is not a coincidence. See Premiumisation and China coffee market.

To verify — the older exam format, and two claims that don't hold up

How many tests? Descriptions of the pre-CVA CQI exam disagree: CQI’s own long-form arabica/robusta document is cited for 19 tests, a CQI-aligned study guide for twenty (20) individual tests over six days with failed sections retakeable within 18 months, an independent pathway guide for 19, and a YouTube explainer for 22 (all accessed 2026-07-23 via the research report). None of these matches the 9 assessments the SCA lists today. Best reading: the count changed across programme revisions, so any specific number should be tied to a specific era — not stated as the number. Minimum age. Q Grading Rules and Regulations v4.5 (April 2020) is cited as requiring students to be 16 before the course start date; the PDF was retrieved but not machine-readable, so this is unconfirmed and may predate the current programme. Stock exchanges. A secondary video source claims Q scores are “valid on the London and New York stock exchange.” No CQI, SCA, or exchange document supports this. Q scores are a quality signal in physical trade; the exchanges trade standardised futures contracts, which is a different thing. Treat the claim as wrong until shown otherwise. The 2023 CVA date and the FastTrack route. The research report cites an SCA Education page for the claims that CVA was introduced in 2023 and that existing Q Graders could convert via a “CVA for Cuppers” course taken by 31 December 2025. That page (education.sca.coffee/q-grader-1) now returns 404, so neither the date nor the deadline could be confirmed at the source.
