How tenders are evaluated & scored

You can’t write to win marks you don’t understand. Tender evaluation follows a structured, surprisingly consistent logic — and once you can see how marks are awarded, every decision about what to write and how to price gets easier. This guide opens the black box.

Quality vs price weighting

Almost every tender splits the total score between quality and price — 60/40, 70/30, 50/50, sometimes 80/20. This single ratio should shape your whole approach. On a 70/30 quality-led tender, a sharper price can’t rescue mediocre answers; the marks live in the writing. On a 30/70 price-led commodity bid, the reverse holds. The weighting is always published — read it first, and let it tell you where to spend your effort. Ignoring it is one of the common reasons bids fail.

Quality scoring scales

Quality answers are typically marked on a scale — commonly 0 to 5, sometimes 0 to 4 or 0 to 100 — with each level defined. A typical 0–5 scale runs from 0 (no response / non-compliant) through 1–2 (partially addresses the question, limited evidence), 3 (satisfactory, meets requirements), to 4–5 (good to excellent: fully addresses every requirement with strong, specific evidence). The jump from a 3 to a 5 is almost always about evidence and completeness — the difference between a competent answer and a convincing one. Knowing the scale tells you exactly what “full marks” requires.

How price is scored

Price scoring is formulaic, and the formula matters enormously. Two common approaches behave very differently: scoring against the lowest price (the cheapest bid gets full price marks, others scored in proportion) rewards aggressive pricing heavily; scoring against the average can penalise outliers in both directions, rewarding sensible rather than rock-bottom prices. There are many variants. The critical point: the formula is usually published, and pricing without reading it is gambling. The same headline price can score very differently depending on the mechanism.

Combining the scores

Each quality answer’s score is multiplied by its weighting and summed; the price score is calculated by formula and weighted; the two combine into a total, and the highest total wins. A worked sketch: on a 60/40 split, a bid scoring 85% on quality and 70% on price scores (0.85 × 60) + (0.70 × 40) = 51 + 28 = 79. A rival at 75% quality and 90% price scores 45 + 36 = 81 — and wins, despite weaker quality, because the price gap outweighed the quality gap under that weighting. This is exactly why reading the weighting first is non-negotiable.

Moderation and the panel

Quality scores usually aren’t one person’s opinion. Multiple evaluators score independently, then moderate — meeting to agree a consensus score for each answer, defensible against challenge. This has a practical consequence for how you write: your answer must give evaluators the evidence to justify a high score to their colleagues. An answer a sympathetic reader might mark generously won’t survive moderation unless the evidence is on the page. Write for the moderation meeting, not just the first read.

What this means for your bid

• Read the weighting first — it dictates where your effort earns the most marks
• Write to the scale — know what a 5 requires and build every answer to clear that bar
• Evidence everything — the gap between satisfactory and excellent is specific, defensible proof
• Read the pricing formula before setting your price — the mechanism changes the optimal number
• Write for moderation — give evaluators what they need to defend a top score

Understanding evaluation is what turns bid writing from guesswork into method. It underpins everything in our guide to writing a winning bid, and it’s the lens our bid review service applies to your drafts — marking them exactly as a real panel would.

Reverse-engineering the scoring before you write

The most useful habit this understanding unlocks is reading every tender backwards — from the marking scheme to the questions, not the other way round. Before drafting anything, build a simple map: each question, its weighting, its scoring scale, and what the published criteria say a top-band answer must contain. That map tells you exactly where the marks live and how to spend your finite effort. A 20%-weighted question deserves several times the attention of a 4% one; an answer scored 0–5 where only a 5 meaningfully outscores rivals demands you build explicitly to the top descriptor, not merely to “good”.

This is also where pricing strategy and quality writing connect. Once you know the quality/price split and the pricing formula, you can model how a given price translates into marks and whether the marginal effort is better spent shaving cost or strengthening a weak answer. On a quality-led split, an extra evidenced example that lifts a 3 to a 5 will usually beat a price cut; on a price-led commodity bid, the reverse. Bidders who skip this modelling are, in effect, competing blind.

Writing for the second reader

Remember that your real audience is often not the first evaluator but the moderation meeting — the consensus discussion where independent scores are reconciled into a defensible mark. An answer that a generous reader might reward will be marked down in moderation if the evidence isn’t on the page for a sceptical colleague to point to. So write for the harder reader: make every claim verifiable, every requirement visibly addressed, every strong score easy to justify. This is precisely the lens our bid review and critique service applies — we score your draft as a moderating panel would, then show you exactly what would move each answer up a band. It is the difference between hoping for marks and engineering them.
