What it means
An evaluation panel may read the same proposal and reach different initial scores, as one reviewer notices a strong implementation plan while another finds its staffing evidence thin. Start with the scoring rules chosen before offers are opened, and if a procurement plan calls for averaging rather than consensus, use and document that method.
Individual assessments can reveal what needs discussion, so keep each evaluator's original score and reason, then record the agreed result and the evidence that changed the view. The New Zealand Government Procurement guide describes individual scoring followed by either mathematical averaging or a moderated consensus, and it recommends recording the full assessment and the reasons for supplier rejection.
A meeting chair should give every reviewer room to explain a material difference, and a senior person's preference should not silently override someone who has identified a missing mandatory requirement. A mandatory eligibility check belongs before scored comparison under the applicable rules, so a bidder missing a required licence might not be eligible for scoring.
Keep price and technical assessments separate when the tender method requires that separation, and note that the World Bank describes a two-envelope approach for certain rated-criteria procurements. Use evidence from each bid and permitted clarification, because hearsay about a supplier, a panel member's personal taste or an unannounced criterion should not determine a score.
If new information is admitted, record why it was admissible for every bidder. Minutes should distinguish discussion from final decision.
Record who attended, any conflict declarations, what evidence was reviewed, individual-to-final score changes and dissent or unresolved issues, and follow the applicable confidentiality and retention requirements. A score can be numerically correct while the rationale is weak, so if two bids receive different points for the same documented capability, the panel should explain the difference or correct an inconsistency, and a calibration example before live scoring may help.
Do not rewrite an evaluator's original file to match the consensus; preserve both versions and any agreed corrections. The panel recommendation should connect final scores to stated requirements and commercial value, although the approving person may still have a separate decision under policy.
For owners, the record reduces reliance on memory after a complex procurement. It makes a supplier choice explainable without pretending that every qualitative judgement is an exact measurement.
Review the process after award to improve the next tender.
In practice
Real-world examples.
Example
Three panel members score a service approach at 6, 8 and 8 before discussing the staffing evidence.
Example
A panel records why an unsupported implementation promise does not meet the published scoring guide.
Example
The final score and original scores remain in the file with named reviewers and dated reasons.
Formula
Calculation
Illustrative score change = Agreed final criterion score - Individual initial criterion score. A change of 2 points is a prompt for a documented reason, not proof of bias. If the published method uses weighted scoring, apply the weights stated before bids were opened.
Worked example. Three reviewers initially give an offer 6, 8 and 8 on a ten-point quality criterion. After checking the same staffing schedule, they agree on 7. The record retains 6, 8, 8 and 7, plus the evidence and rationale. It does not automatically use their 7.33 average.
Do not add scores from different scales or weightings. The procurement plan and current tender rules determine the calculation, moderation method and approval path.Case study
Seen in the real world.
This illustrative and entirely fictional example follows Greenline Estates, an invented property manager. It receives three bids for maintenance services. One bidder offers a low price, but two reviewers disagree sharply about whether its weekend coverage meets the published service criterion. The panel re-reads the bidder's timetable and checks the tender wording. It asks a permitted clarification through the controlled channel, then records how each reviewer assessed the response.
A moderator ensures the supplier is judged on the same published criterion as its rivals. In this fictional case, the panel reaches an agreed score and leaves the original scores visible. The approval manager can trace the decision without replacing the evidence with a vague note saying the team preferred another company. No contract is awarded merely because the record exists.
Watch out
Common mistakes.
- Replacing initial scores with final scores and losing the reason for changes.
- Adding a criterion after seeing which supplier it favours.
- Treating a moderation meeting as permission to ignore eligibility or conflict rules.
Questions
People also ask.
Is moderation always required?
No. Follow the method stated in the procurement plan and applicable rules; some processes use averages instead.
Should original scores be retained?
Yes, where policy permits, keep initial assessments and the reason for the final score so the decision can be reviewed.
Does a final score automatically award the contract?
No. An authorized award decision and contract process may still be required.
