Not every difference between a CV and a public source is meaningful. Good verification distinguishes normal variation from a conflict that changes the substance of a professional claim.

Scope and approach

This article presents an evidence-classification framework rather than a prevalence study. It uses limitations disclosed by official databases to show why a missing record and a contradictory record must be treated differently.

Material discrepancies

Differences are more important when they alter authority, qualification, ownership, or scale.

  • CEO versus an operational or advisory role
  • Completed degree versus attendance only
  • Winner versus finalist or honorable mention
  • Founder versus early employee
  • A materially different investment, revenue, or funding amount
  • Employment dates that create a substantial unexplained overlap

Differences that often are not discrepancies

  • A publication year differing from the later award year
  • A shortened paper or presentation title that clearly refers to the same work
  • Month-level date differences caused by payroll, announcement, or transition timing
  • Equivalent title wording across countries or business units
  • A company rename, acquisition, or former legal name

Require direct, eligible evidence

A discrepancy should be based on a source that is both credible for the fact and directly conflicting. Search-result snippets, copied biographies, and absence of evidence are not enough. Explain the conflict neutrally and recommend the most authoritative document that could resolve it.

Use proportionate follow-up

Ask the candidate for clarification before drawing a conclusion. A corrected CV, degree record, employer letter, licensing lookup, publication record, or financing announcement may resolve the issue quickly.

How CredVerity applies this evidence

From research method to repeatable workflow

CredVerity requires direct, eligible conflicting evidence before assigning Discrepancy found. Small timing differences and compatible title variants remain contextual unless they materially change the claim.

Public-source verification can be incomplete and should not be the sole basis for a consequential decision. Confirm material findings directly with the person or an authoritative source.

    The Department explicitly states that reported accreditation information is not audited and may not be accurate, current, or complete—an important example of why absence alone is not a conflict.
