Quote the snapshot, not the live counter. The live figure is true right now and will be wrong by tomorrow; 4,346 results have been added since the 2026-09-22 snapshot alone. The dated snapshot is the number that will still reconcile when someone checks your citation.

Per-instrument score distributions — which results are common, which are rare, and how the split moves between languages — are published on the distributions pages, and internal-consistency reliability per scale on the reliability page.

Read this as session geography, not respondent nationality. It is derived from the IP address of anonymous sessions that completed at least one test — 409,914 of them across 217 countries and territories — and a result row carries no country of its own. VPNs, travel and shared connections all land in here, and one person can be more than one session.

62.8% of results carrying a language tag — 366,278 of 583,137 — were taken in a language other than English. That is what makes cross-language comparison on the same instrument possible at all. Results with no language recorded are excluded from both sides of that share rather than counted as English: we do not know what language they were taken in, and defaulting the unknown to the majority is how a corpus gets described as more English than it is.

Times are measured over 563,282 results that recorded a duration, not estimated from question counts. The completion rate is measured on the instrumentation event stream — 716,878 completion events against 865,015 start events — which is a different counter from stored results and does not reconcile with it row for row. It is the honest way to state “how many people who begin a test get to the end”; it is not “the share of visitors whose result we hold”.

What we publish, and what we don’t

Open on this site

  • Everything on this page
  • Score distributions per instrument and per language
  • Internal-consistency reliability per scale
  • The Big Five technical manual in full
  • Two frozen anonymised response datasets — 54,431 and 77,284 rows — free, CC BY 4.0, mirrored with DOIs

Under agreement only

  • Raw responses from the live corpus, and any per-row data
  • Per-item statistics, item difficulty above all
  • The question banks
  • De-identified extracts cut to a study design
  • Fielding a new instrument to our respondent stream

Item difficulty is a map of the question bank; published openly it would damage the instruments it describes. It goes to research partners and nowhere else.

Licence and how to cite us

Everything published on this page is free to reuse, including commercially, on one condition: say where it came from.

Licence

CC BY 4.0

Creative Commons Attribution 4.0 on the aggregates published here — the counts, distributions, reliability figures, geography, language mix and completion times. Copy them, chart them, put them in a paper, a deck or a product. The only requirement is attribution.

The two downloadable response datasets carry the same licence, stated on their own pages.

Ready-made attribution

Under a figure, in a chart caption or in a slide footer — this line, as it stands:

Data: JobCannon Assessment Response Corpus (snapshot 2026-09-22), https://jobcannon.io/research/data

In a reference list, the full form:

JobCannon (2026-09-22). JobCannon Assessment Response Corpus
(snapshot of 594,590 completed assessment results, 2026-02-22 to 2026-09-22).
Retrieved from https://jobcannon.io/research/data.

Two details that are not decoration. Name JobCannon in the running text where the figure appears, not only in the reference list — a reader should be able to see whose data they are looking at without turning to the back. And keep the snapshot date: the corpus grows every day, so a figure quoted without its date cannot be reconciled by anyone checking it later.

Beyond the published aggregates — raw responses, per-row extracts, per-item statistics, a custom cut of the corpus — is not covered by the licence above and is arranged with us directly; see our terms.

Common questions

How many people have taken a JobCannon assessment?

594,590 assessments had been completed as of 2026-09-22, the date of the published snapshot; the live figure on this page is higher and updates hourly. Results were collected between 2026-02-22 and 2026-09-22 across 194 distinct instruments.

What is in the JobCannon response corpus?

Completed, scored results from 194 self-administered assessments — personality inventories, cognitive tests, interest inventories and screeners — taken in 28 interface languages by sessions from 217 countries and territories. Each result carries the instrument, the scored output, the interface language and how long it took. Names, emails and free text are not part of any published aggregate.

Is the JobCannon dataset representative of the general population?

No. It is a convenience sample of people who chose to take a test on jobcannon.io — self-selected, unproctored, unpaid and not quota-balanced on age, sex, education or country. Its value is scale, language coverage and the fact that every instrument has published reliability, not representativeness. Any comparison to a population norm has to be made carefully and said out loud.

How long does a JobCannon assessment take to complete?

The median completed assessment takes 3 min 21 s, with the middle half falling between 1 min 51 s and 6 min 7 s. That is measured over 563,282 results that recorded a duration, not estimated from question counts.

Can I download JobCannon assessment data?

Two frozen, anonymised response datasets are free to download under CC BY 4.0 — 54,431 rows across the psychometric instruments and 77,284 rows of entertainment quizzes. The full live corpus is not downloadable: its aggregates are published on this site, and de-identified extracts are prepared for research partners under agreement.

Is JobCannon assessment data reliable?

Internal-consistency reliability is computed from our own answer vectors and published per scale for 23 assessments, last recomputed 2026-08-06 — including the scales that score badly. 66 of our 195 tests implement a published, peer-reviewed instrument; a wider 137 sit on the serious shelf, which also holds typological frameworks such as MBTI and DISC that are established but not peer-reviewed in that sense. The remainder are labelled entertainment rather than mixed in.

How do I cite JobCannon research data?

Use the prepared line: Data: JobCannon Assessment Response Corpus (snapshot 2026-09-22), https://jobcannon.io/research/data. Keep the snapshot date — the corpus grows daily, so a figure quoted without one cannot be reconciled by anyone checking it later — and name JobCannon in the running text, not only in the reference list.

What licence is JobCannon research data published under?

The aggregates published on this page — counts, distributions, reliability, geography, language mix and completion times — are CC BY 4.0 (Creative Commons Attribution 4.0), free to reuse including commercially, with attribution. The two downloadable response datasets carry the same licence. Raw responses, per-row extracts and per-item statistics are not covered by it and are arranged with us directly.

Need more than the aggregates?

De-identified extracts cut to a study design, item-level statistics, a human baseline for model evaluation, or a new instrument fielded to a live respondent stream — all of it is available to research partners under agreement.
