One of the most common reasons organisations lose tenders is surprisingly simple:
They do not fully understand how their submission will be evaluated.
Many suppliers spend weeks developing solutions, writing responses and gathering evidence, only to discover that they have answered the question they wanted to answer rather than the question the evaluator was actually scoring.
Understanding bid evaluation criteria is therefore one of the most important skills in bid writing. It allows organisations to focus effort where it matters most, align responses to buyer expectations, and maximise available marks.
In this guide, we explain how public sector bid evaluations typically work, what scoring methodologies look like, what differentiates an average response from a high-scoring one, and how to interpret evaluation criteria before writing a single word.
Why Understanding Evaluation Criteria Matters
Every public sector procurement exercise is effectively a competition.
The buyer has a set of requirements and a methodology for assessing how well each bidder meets those requirements. The supplier with the highest overall score will often be awarded the contract.
However, many organisations focus almost entirely on answering the question and overlook how the response will actually be scored.
Before writing begins, bid teams should ask:
- What is the buyer evaluating?
- What evidence are they looking for?
- How are marks allocated?
- What separates a passable answer from an excellent answer?
- How much weighting does each question carry?
Understanding these factors should shape the entire bid strategy.
This is why evaluation analysis should form part of your wider Bid Qualification, Capture Strategy, and Bid Planning processes.
Even experienced suppliers regularly lose marks for avoidable reasons, including:
- Only answering part of the question
- Repeating the specification rather than explaining delivery
- Making claims without evidence
- Failing to provide measurable outcomes
- Using irrelevant case studies
- Describing activities rather than benefits
- Not addressing risks and mitigations
- Submitting generic content copied from previous tenders
- Failing to demonstrate understanding of the buyer’s priorities
Many responses fail not because the proposed solution is poor, but because the bidder has not adequately demonstrated why their approach will be successful.
What does ‘Bid Evaluation Criteria’ mean?
Before analysing individual question scores, it is important to understand how most public sector procurements are evaluated at an overarching level.
Whilst every procurement is different, most UK public sector tenders assess submissions across three broad areas:
Quality – Typically accounting for between 50% and 80% of the overall score, quality evaluates how the bidder intends to deliver the contract. This often includes:
- Methodology
- Staffing
- Mobilisation
- Risk management
- Contract management
- Service delivery
- Innovation
- Continuous improvement
For many contracts, quality is the largest contributor to the overall evaluation score.
Price – Price weightings commonly range between 10% and 40%, depending on the sector and procurement approach.
Buyers are rarely looking for the cheapest provider. Instead, they are seeking the most economically advantageous tender (MEAT) or, under the Procurement Act 2023, the Most Advantageous Tender (MAT).
This means pricing is typically assessed alongside quality rather than in isolation.
A bidder may submit the lowest price but still lose if quality scores are significantly lower than competitors.
Social Value – Many contracting authorities now include dedicated Social Value weightings, typically ranging from 10% to 20%.
These questions assess the wider benefits suppliers will deliver alongside the core contract, such as:
- Local employment opportunities
- Apprenticeships
- Volunteering initiatives
- Environmental improvements
- Community engagement
- Supply chain opportunities for SMEs and VCSEs
In some procurements, Social Value may be evaluated as a standalone scored section, whilst in others it may be embedded throughout quality responses.
Example Evaluation Structures
Health & Social Care Contract
| Area | Weighting |
|---|---|
| Quality | 70% |
| Price | 20% |
| Social Value | 10% |
Security Services Contract
| Area | Weighting |
|---|---|
| Quality | 60% |
| Price | 30% |
| Social Value | 10% |
Construction Framework
| Area | Weighting |
|---|---|
| Quality | 55% |
| Price | 35% |
| Social Value | 10% |
Employability & Skills Contract
| Area | Weighting |
|---|---|
| Quality | 65% |
| Price | 15% |
| Social Value | 20% |
The key takeaway is that a bid should never be viewed purely through the lens of individual question scores. Organisations must understand how those scores contribute towards the overall evaluation model and where the greatest opportunities to gain competitive advantage exist.
For example, a bidder may spend significant time refining a pricing model worth 15% of the overall score whilst neglecting quality responses worth 65%. Understanding the evaluation structure allows resources to be directed towards the areas with the greatest impact on the final result.

Understanding Quality Scoring
Whilst price and social value are often assessed using predefined formulas or scoring frameworks, quality responses are usually evaluated by human assessors. This means understanding how evaluators think is critical to maximising scores.
Most public sector tenders use either a 0–5 or 0–10 scoring scale. Although terminology varies between commissioners, the principles are generally similar.
Typical 0–5 Scoring Matrix
| Score | Typical Description |
|---|---|
| 0 | Unacceptable – no response or fails to meet requirements |
| 1 | Poor – significant concerns or major omissions |
| 2 | Fair – partially addresses requirements but lacks detail or evidence |
| 3 | Good – meets requirements and provides a satisfactory response |
| 4 | Very Good – exceeds requirements in several areas with strong evidence |
| 5 | Excellent – fully addresses requirements with comprehensive evidence, innovation and added value |
One of the biggest misconceptions in bidding is that answering the question automatically results in maximum marks. In reality, a compliant answer will often achieve a score of 3 out of 5, because it demonstrates that the bidder understands and can meet the requirement.
To achieve higher scores, bidders must provide evaluators with confidence that their proposed approach will deliver successful outcomes.
Not All Quality Questions Are Equal
Many bidders focus on overall quality percentages but overlook the weighting of individual questions.
Not All Quality Questions Are Equal
| Question | Weighting |
|---|---|
| Methodology | 25% |
| Mobilisation | 10% |
| Staffing | 10% |
| Quality Assurance | 5% |
In this example, the Methodology question carries five times the value of the Quality Assurance question.
Yet many organisations spend similar amounts of time writing both responses.
Understanding question weightings enables bid teams to prioritise:
- Senior reviewer input
- Evidence gathering
- Storyboarding
- Graphic design
- Final quality assurance reviews
The strongest bid teams allocate effort in line with scoring potential.
The Difference Between Good and Excellent
Following individual assessments, many public sector procurements undertake a moderation process where evaluators discuss scores and agree a final consensus score. This means isolated strong statements are rarely enough to achieve maximum marks. Responses must consistently demonstrate evidence, credibility and value throughout, enabling multiple evaluators to independently reach the same positive conclusion.
Consider a question asking:
“Describe your approach to recruiting and retaining staff.”
A response scoring around 3/5 may include:
- Recruitment advertising
- Interview processes
- Induction arrangements
- Mandatory training
Whilst this answers the question, it primarily describes activities.
A response scoring 5/5 would typically go further by:
- Explaining the recruitment methodology
- Demonstrating understanding of local labour markets
- Providing measurable retention data
- Evidencing successful delivery on similar contracts
- Identifying risks and mitigations
- Offering additional value beyond the specification
For example:
“Across our current domiciliary care contracts, we maintain an annual staff retention rate of 87%, supported through structured career pathways, quarterly development reviews and access to over 120 CPD modules. This approach has reduced vacancy rates by 22% over the previous two years.”
The difference is subtle but important. Rather than simply explaining what will happen, the bidder demonstrates why the approach works.
Further examples include:
Health & Social Care

“Describe how you will maintain continuity of care.”
3/5 Response:
- Staff rotas managed weekly
- On-call arrangements in place
- Relief staff available
5/5 Response:
- Dedicated locality-based care teams
- Digital scheduling and call monitoring
- Contingency staffing pools
- Escalation procedures
- Real-time service oversight
- Evidence of 98%+ visit fulfilment
- Service-user satisfaction data
- Case study demonstrating successful continuity during periods of high demand
Employability & Skills
Question:
“Describe how you will engage employers.”
3/5 Response:
- Employer engagement team
- Vacancy sourcing
- Job brokerage activity
5/5 Response:
- Employer advisory boards
- Sector-specific recruitment campaigns
- Vacancy forecasting
- Employer-led curriculum design
- Evidence of employer satisfaction rates
- Progression outcomes
- Case studies demonstrating sustained employment
Construction & Professional Services
Question:
“Describe your approach to managing project risks.”
3/5 Response:
- Risk register maintained
- Monthly reviews undertaken
5/5 Response:
- Risk workshops at project inception
- Quantified risk assessment methodology
- Escalation thresholds
- Early warning mechanisms
- Lessons learned integration
- Evidence from comparable projects showing successful risk mitigation
The “What, How, Evidence, Outcome” Model
One of the simplest ways to improve quality scores is to structure responses around four key elements:
- What? – What are you proposing to do?
- How? – How will it be delivered?
- Evidence? – Where have you successfully done this before?
- Outcome? – What measurable benefit will this create for the commissioner?
Many responses focus heavily on the “what” and “how” but overlook evidence and outcomes. Unfortunately, these are often the areas that move a response from a 3/5 to a 5/5 score.
What Evaluators Are Really Looking For
Across hundreds of evaluations, we have found that buyers are typically assessing five underlying factors:
- Understanding – Have you understood the requirement and the buyer’s objectives?
- Credibility – Is the proposed solution realistic and deliverable?
- Evidence – Can you demonstrate previous success?
- Risk Management – Have you identified potential challenges and explained how they will be managed?
- Added Value – What additional benefits will the commissioner receive beyond the minimum specification?
The highest scoring responses address all five areas, whether explicitly stated within the question or not.
Why Two Bidders Can Receive Different Scores?
It is important to remember that quality evaluations are conducted by people, often from different operational, commercial and procurement backgrounds.
Whilst evaluators are trained and moderated to ensure consistency, they can only score the evidence presented within the response. They cannot assume capability, infer meaning or award marks for information that has not been clearly articulated.
This is why two organisations with similar delivery capability can receive significantly different scores. Often, the difference is not the solution itself, but how effectively that solution has been evidenced and explained.
A common phrase within bid management is:
“Evaluators can only score what they can see.”
The highest scoring bidders make it easy for evaluators to identify requirements, evidence, outcomes and added value without having to search for them. This is down to effective Bid Evidence and Writing.
Before writing any response, ask yourself:
✓ Do we understand the overall evaluation model?
✓ Do we know the weighting of each question?
✓ Have we reviewed the scoring matrix?
✓ Do we know what a maximum score looks like?
✓ Have we identified the evidence needed?
✓ Have we linked our solution to commissioner outcomes?
✓ Have we included measurable results?
✓ Have we demonstrated added value?
✓ Have we addressed risks and mitigations?
✓ Have we made it easy for evaluators to award marks?
If the answer to any of the above is “no”, there is likely an opportunity to improve the submission before writing begins.
