CAIBOK — anchor and elective policy

Version 1.0 · 2026-07-23. Why some exams are required, why others are not, and what each kind of exam is allowed to claim.

The rule

Anchors and capstones must trace to an analysed task area. Electives need not.

An anchor makes a competence claim and is therefore bound by the job-task analysis. An elective is professional development — it broadens the holder without being part of what the credential attests.

Everything below follows from that one sentence.

Anchors

An anchor is a subject a professional at that level would be unqualified without. Anchors are required for the belt.

Every anchor must satisfy all four:

1. It traces to at least one task area in the job-task analysis (CAIBOK-JTA-progression-matrix-DRAFT.csv), at that belt's level.
2. The task area is supported by evidence — practitioner or employer evidence, or published regulation. Not opinion.
3. Its content is assessable in writing. Anything requiring psychomotor demonstration is out of scope for a written anchor (see the scope statements).
4. Absence would be a competence gap, not merely a narrower professional.

Current anchor sets:

Anchors are defined in one place — beltframework::ANCHORS — which is the single source of truth for the site, the public JSON feed, and the award engine. They are never hard-coded downstream.

Electives

An elective is a subject that broadens a professional without being required to practise at that level. Electives count toward the belt in number, not in identity: the belt requires N electives, not particular ones.

An elective must: - sit within a CAIBOK pillar and belt level; - be assessed to the same standard as any other exam (same authoring rules, same validation, same pass mark methodology); - be honestly described.

An elective need not trace to a task area.

Why that is legitimate, not a loophole

The credential's competence claim is carried by the anchors and the capstone. If the analysis does not support requiring a subject, CAIBOK does not require it — but it may still offer it.

That is what makes subjects like Pest Management, POS Systems and Menu Engineering defensible. They are real, useful professional knowledge. They are not things a chef de partie is unqualified without, so they are not anchors — and no CAIBOK credential claims they were assessed as part of its competence statement.

The alternative — requiring everything useful — would inflate the credential beyond what the analysis supports, which is precisely the failure mode scope control exists to prevent.

The Black Belt pillar minimum

Black requires 3 electives with at least one from Professional Cooking. This is a deliberate hard requirement: a Chef de Cuisine who has broadened only into business subjects has drifted from the craft the credential is named for. It is enforced by the award engine, not by guidance.

What each kind of exam may claim

A subject badge attests that the holder passed that exam. It does not attest a level of practice, and it is not a certification. Only belts and named certificates are certifications.

Changing the classification

Moving a subject between anchor and elective changes what a credential attests, so it is a scheme change:

1. Evidence is presented — job-analysis data, regulation, or practitioner input.
2. The Board of Trustees decides (reserved authority, CAIBOK-GOV-001 §4.2).
3. beltframework::ANCHORS is updated as the single source of truth.
4. The change is published, with its effective date and the treatment of holders certified under the previous rule.

Precedent (2026-07-23): subject 2120 Workplace Safety was reclassified from elective to a fourth Brown anchor. Rationale: it was Brown's only elective, and required workplace-safety knowledge should not be optional at the entry rung. The SA-WORKER task area was added to the job analysis in the same change so the requirement traces to analysed work — the anchor and its evidence were introduced together, which is the order this policy requires.

Review

Reviewed at least annually and whenever the job-task analysis is revised.

Appendix — how examination blueprints are weighted

Blueprint weight comes from how critical a task is, not how often job advertisements mention it.

This is a deliberate override, and it needs stating because the evidence is counter-intuitive. Across 136 chef job advertisements in 18 countries:

Weighted by advertisement frequency, allergen management would be worth 3% of supervision, and pest management would be worth nothing at all. That would be indefensible: allergen failures kill people, and pest activity closes kitchens.

Employers advertise the management and assume the safety. A job ad is a recruitment document, not a task analysis — it lists what distinguishes candidates, not what the job requires. Frequency data is therefore evidence of market language, not of criticality.

Blueprint weights are set from practitioner-rated criticality — how serious the consequence of failure is, and how often the task is performed — validated by panel. Advertisement frequency is retained only as supporting evidence that a task area exists in real work.
