§1
The AFQT formula.
Verbal Expression (VE) = WK + PC. Raw composite = 2·VE + AR + MK. We convert the raw composite to a 1–99 percentile via the 1997 Profile of American Youth norm tables — a stable, publicly published mapping the DoD has used since the formula change.
§2
Branch line-score formulas.
Five branches define a fixed catalog of named composites. The Coast Guard does not: it publishes no names at all, and each rating lists its own combination of subtest scores instead. We record which model a branch uses in the data rather than assuming one, so a branch is never shown a catalog it does not have. Use the branch index to compare all six AFQT floors, composite systems, and job indexes from one canonical hub.

§3
Freshness policy.
- Every numeric claim shows a
last verifieddate. - > 120 days = warning ribbon. > 180 days = page goes
noindexpending re-verify. - Quarterly diff-watcher runs across all five branch sources; a human reviews every change before promotion.
The source manifest lists every cited primary URL and its latest verification date.
§4
Practice items and originality.
All practice items are self-authored against the published ASVAB content-area specs. We do not reproduce, paraphrase, or thin-rewrite copyrighted ASVAB items. An originality audit (cosine ≥0.85 dedupe + sample human spot-check) runs on every batch.
Explanations are pre-generated (one canonical + two alternatives) and stored as static text alongside the item — no runtime LLM call. AI-explained answers are labeled with the reviewer name once human review completes.
§5
Change log.
- 2026-08-08 — initial methodology page; first 43-job sample published with branch profiles, composite formulas, and AFQT calculator. Remaining ~480 jobs and 5,000 items are queued for staged release.
