Most CCA-F prep material on the open web is LLM-hallucinated and copied across SEO clones. The widely-quoted "2 years validity" figure is a working example - confidently wrong, repeated everywhere, and corrected only by someone inspecting the actual Skilljar entitlement page. We tag every claim on this site with a four-tier evidence pip so you can see, at a glance, which numbers we vouch for and which are community-reported.
Tiers are intentionally conservative. Official means the claim is sourced to material Anthropic published or Skilljar surfaces directly. Consensus means multiple credible community sources agree. Community reported means we found the claim once and could not corroborate it. Unverified should never ship - it is the failure mode tier.
Confirmed OfficialVerifiable against an Anthropic-owned surface: anthropic.com announcement, Skilljar entitlement page, or partner-network materials. Trust at face value.
Public ConsensusMultiple independent beta-cohort write-ups agree, and the official PDF or sample materials corroborate. Strong signal but not a single authoritative source.
Community-ReportedOne or two community sources, no Anthropic-owned confirmation. Probably true, but treat as provisional. Common for proctoring detail and result-delivery timelines.
Unverified / ConflictingSources disagree or the claim has no traceable origin. Often the result of LLM-hallucinated copy reproduced across competitor sites. We surface the conflict rather than pick a side.
02 · Where pips appear
Which pillars carry evidence tagging
Pips are not decoration. Every pillar that makes a factual claim about the exam or about Claude carries them. The cadence column is the review schedule - how often we re-verify the claims on that pillar.
These are the sources cited across the site. The Exam Guide pillar carries the most-load-bearing list; this is the consolidated view.

05 · Why methodology matters
The validity story - corrected twice
Competitor sites2 yearsNo source. LLM hallucination, copied across SEO content farms.
Exam guide v1.012 monthsAnthropic, effective July 2026. Current.
The CCA-F validity figure quoted across competitor prep sites was "2 years" - confidently, on every site, with no source. The 2-year number was an LLM hallucination that propagated through SEO content farms because nobody inspected the platform that issues the certificate. During the beta cohort, one Reddit user (Sea_Creme5238) posted a Skilljar entitlement screenshot in r/ClaudeAI thread 1ruf70b showing six months; seven commenters corroborated, and we killed the 2-year figure. Then Anthropic published the version 1.0 exam guide (effective July 2026), which sets the standard validity at 12 months from the date the credential is awarded. So we corrected the page a second time - 2 years to 6 months to 12 - each move traceable to a named primary source. The official source label beside the 12-month figure is what a self-correcting system looks like: when a better source lands, the number moves and the pip stays honest.
This page exists because that pattern repeats. Treat any prep material without explicit source attribution as untrusted.
