## Claim
A credential earns employer trust only when it simultaneously proves job-relatedness (built from a real job task analysis, not a topic list), enforces administration security (identity verification, proctoring, multiple exam forms, statistical item analysis), and stays independent of any single educational path — missing any one of the three leaves it functioning as a weaker signal than its holders assume.
## Evidence
Source: [[3. Resources/Literature Notes/Building Trust Inside the WordPress Advanced Professional Developer Certification (Klaus & Dr. Leslie)]] — Dr. Leslie (Criterion's Chief Psychometric Officer) names these three properties as what distinguishes certification from training or a degree, and the talk's described build pipeline (job task analysis → blueprint → SME item writing → beta test → cut score) is the mechanism that makes each property real rather than claimed.
## Scope & conditions
- Holds for high-stakes professional certifications used in hiring, staffing, or promotion decisions — where the cost of a false-positive "qualified" signal is real (a bad enterprise hire, a failed high-traffic deployment).
- Breaks down for low-stakes badges or participation certificates, where the security and job-task-analysis rigor this claim requires aren't warranted or cost-justified — most course-completion badges reasonably skip all three properties.
- Even where all three properties are genuinely present, the credential can still be misused as a proxy screen if employers stop checking the underlying work it certifies — see the companion caution below.
