The Koydo Tutor Quality Standard

The nine constitutional principles

1. 1.Multi-component, never single-exam.
2. 2.Multi-modal assessment with per-modality minimums.
3. 3.Tiered ladder plus a time-limited Examiner/Assessor track.
4. 4.Two-axis scoping: pedagogy tier × subject content scope band.
5. 5.Marketplace-native, server-computed evidence — never self-reported.
6. 6.Verifiable + portable (Open Badges 3.0 / W3C VC).
7. 7.Published, evidence-graded standards with a public crosswalk.
8. 8.Integrity controls: proctoring, AI + human scoring, audited hours.
9. 9.Renewal/recertification; lapses auto-invalidate the verify page.

The tier ladder

A universal pedagogy ladder crossed with a subject content scope band. Higher tiers are earned through real teaching milestones; the tutor's fee at Advanced and Master primarily funds an independent external expert who reviews and scores their teaching — a stricter, independent check.

The multi-modal entry exam (Tier 1)

A 4-hour, proctored, identity-bound battery. Each subject declares its modality set with per-modality weights and minimum cut-scores — you cannot pass by acing one modality and failing another. For language: listening comprehension and learner-error spotting, reading and error classification, written corrective feedback, and recorded spoken modeling and feedback via the Speaking Lab. For math (same engine, config only): computation, conceptual explanation, diagram reasoning, recorded spoken worked-explanation, written work-shown, and error-diagnosis.

Evidence grading

Every design choice is labeled by the strength of the research base behind it — the NSSA convention.

Integrity, consent & data protection

Recorded lessons follow a tutor-full / learner-minimized model: permanent training proof is the tutor's own audio-video plus the learner rendered as a de-identified transcript (no name, face, or voice) and the rubric scores. Raw full recordings are ephemeral and auto-purged on a short clock. Tutors consent to indefinite storage of their own artifacts; any learner-side recording requires a stored parent/guardian approval and an audit-log row, and absent consent the lesson proceeds un-recorded and does not count toward progression. No minor personal data is retained indefinitely, so data-minimization and erasure rights are honored by design.

Renewal & revocation

Safeguarding checks carry an expiry; an annual re-screen is required. A lapsed or failed check flips the credential to suspended or revoked, and the public verification page reflects it immediately. Expiry and revocation are first-class fields in the Open Badges 3.0 assertion.

Frequently asked questions

Is the Koydo tutor certification just an online exam?

No. A single online quiz is the credibility dividing line most paper-mill certifications fall on the wrong side of. The Koydo credential is multi-component: a 4-hour proctored multi-modal entry exam, a safeguarding background check, logged supervised teaching hours computed from real platform lessons, and observed/scored lessons at higher tiers. The exam alone is only the entry gate, not the whole credential.

How are logged tutoring hours verified?

They are server-computed from real Koydo lessons where the tutor taught, never self-reported. This marketplace-native evidence is auditable and is the core reason Koydo can deliver CELTA/CRLA-grade rigor affordably.

Is the credential portable and verifiable?

Yes. Every credential is issued as an Open Badges 3.0 / W3C Verifiable Credential with a public verification URL, transparent criteria, attached evidence, an issue date, an expiry, and a revocation status — so a school relies on the credential's live status, not a one-time snapshot.

Does it align with CRLA or NSSA?

The standard is crosswalked to CRLA ITTPC topic areas and NSSA's six program-design domains for continuity. Formal accreditation alignment is optional and to-be-decided; Koydo builds to a world-class bar so alignment stays open while pursuing bottom-up recognition.
