What to review
Record the affected entry, the reason for change and the effective date. Preserve access to meaningful methodological differences.
A practical example
Correcting a source transcription error is different from changing the indicator used to rank entities. Readers should be able to identify which occurred.
Keep the claim in scope
Avoid silent revisions that make historical comparisons impossible to interpret. Use the applicable correction process.
Research and editorial context
A result is meaningful within its methodology. Match the research question, assessed universe and measurement period before making a comparison. These reference notes explain evaluation concepts; they do not add indicators, weights or thresholds to any published WCRC study.
Examples illustrate a decision and do not describe a named organisation's conduct. This is a reference note, not a new research finding or an award outcome.
