How tenders are scored — what the evaluation panel actually does

Pactis Partners · 2026

Most bidders imagine a reader. What they get is a scorer: someone with a matrix, a rubric and a governance process that punishes any mark they cannot justify. Understanding that process is worth more marks than any amount of polish.

The mechanics

A formal tender, public or private, almost always separates price from quality and states the split in the invitation — 60/40 and 70/30 quality-to-price are common in services; price-heavy splits appear in commoditised supply. Quality is broken into questions. Each question carries a weighting and is marked on a published scale, typically 0–5 or 0–10, with written definitions for each score ("3 — good: the response meets the requirement with minor omissions…").

Price is usually scored relative to the lowest compliant bid: lowest price takes full marks and others are scaled down proportionally. That means a bid can be the cheapest and still lose, or the dearest and still win, depending on the quality gap.

Who scores, and how

• Several evaluators score independently, usually three to five, often from different functions — the service owner, procurement, sometimes finance or a technical lead.
• Moderation then brings them together. Where scores differ, each evaluator must justify theirs against the rubric. The result is a consensus score with written reasons.
• Every mark must be defensible. Under the Procurement Act 2023, unsuccessful bidders receive an assessment summary explaining their scores; challenges are a live risk. Evaluators therefore score what they can point to on the page.

Why good firms lose marks

What top-scoring answers have in common

1. They mirror the question's structure. If the question lists four things, the answer has four labelled parts, in that order.
2. They put evidence where the rubric looks for it. Named people, named methods, a comparable contract with an outcome.
3. They answer the pressure behind the question. A quality-management question is really "how do I know you won't collapse in month four?" Name the checks and what happens when one fails.
4. They are easy to mark. An evaluator who can justify a 5 in thirty seconds gives a 5. One who has to hunt gives a 3.

We have sat on these panels. The gap between first and second is rarely capability; it is whether the capability was put where the scorer could find it.
