Performance review and categories

NCCF reviews every VVB through witness audits and report reviews, scores each completed activity out of 25, and publishes each VVB’s category on the Registry website.

VVBsLast reviewed 23 October 2026

How performance is reviewed

  • Random witness audits during on-site work
  • Reviews of Validation and Verification Reports, plans and findings

Scoring

Each completed activity is scored 1 to 5 for approach (team selection, audit plan, code of conduct, timeliness) and 1 to 5 for representation (report quality, responsiveness to comments, unbiased accuracy). The score is the product, up to 25. NCCF’s scores cannot be contested.

Categories

CategoryAverage score

Categories are published on the Registry website. IVVEs are reviewed the same way, with input from project proponents, peer reviewers and witness auditors, and can be de-empanelled for poor performance or ethical breaches.
