How Horizon Europe evaluators actually score your proposal

Most applicants imagine an evaluator who reads their proposal cover to cover, admires the science and then assigns a mark. The reality is more mechanical, and understanding the mechanics is the single biggest lever you have.

1. Who reads it, and for how long

Each proposal is assigned to three, sometimes four or five, independent experts. They are selected for the topic, not for your discipline alone, and they read remotely, usually in the evening after their own work. A realistic reading budget for a 45-page Pillar II proposal is 45 to 90 minutes for the Individual Evaluation Report, including writing the comments. For an ERC Step 1, the panel member may have twenty minutes per synopsis.

The practical consequence: the evaluator is reading to answer specific questions, with the criteria open in a second window. Anything that does not help answer those questions is noise, and noise costs you time you do not have.

2. The three criteria and what the scale means

Horizon Europe collaborative actions are scored on Excellence, Impact and Quality and Efficiency of Implementation, each from 0 to 5 with half points, threshold 3 per criterion and 10 overall. The scale descriptors matter more than people think:

• 5, Excellent: the proposal successfully addresses all relevant aspects; shortcomings are minor.
• 4, Very good: addresses the criterion very well, but a small number of shortcomings are present.
• 3, Good: addresses the criterion well, but a number of shortcomings are present.

Notice the word "shortcomings". Evaluators are not asked how brilliant the idea is; they are asked how many of the aspects listed under the criterion are addressed and how well. A proposal with a world-class idea and a vague methodology scores a 3.5 on Excellence, because methodology is one of the aspects.

3. What separates a 4 from a 5

In consensus discussions, the move from 4 to 5 is almost always decided on three things:

1. Evidence over adjectives. "Innovative" and "ambitious" do not score. A table that contrasts the state of the art with your approach, with numbers, does.
2. Traceability. The evaluator can follow a thread from the topic's expected outcomes, to your objectives, to the work packages that deliver them, to the KPIs that prove it. If the thread breaks anywhere, the comment "the link between objectives and work plan is not fully clear" appears, and that is a 4.
3. Answering the sub-criteria explicitly. Each criterion lists aspects: for Impact, for example, the credibility of pathways, the scale and significance of the contribution, and the measures to maximise impact. Proposals that use these words as headings make it easy to find the answer. Proposals that hide the answer in prose make the evaluator work, and tired evaluators do not give the benefit of the doubt.

The question in the panel room is never "is this good science?". It is "can I point to where this proposal addresses each aspect, and how convincing is it?".

4. Consensus: where scores move

After individual reading, the evaluators meet, usually online, with a moderator. The Individual Evaluation Reports are compared. Where scores differ by more than a point, the moderator asks each expert to justify. This is where a strong, specific comment by one evaluator can pull the others up, and where a single clear weakness, once named, pulls everyone down. The consensus report becomes your ESR.

Two implications for writers. First, your proposal should give a sympathetic evaluator the sentences they need to defend you: a crisp statement of the ambition, a visible risk table, a clear impact logic. Second, do not leave an obvious weakness unaddressed hoping no one notices; three independent readers almost always do, and once it is on the table it is in the report.

5. Reading your ESR

If you scored 12 or 13 and were not funded, the ESR tells you exactly which aspects were considered shortcomings. Rewrite those sections first. Resubmitted proposals that address the named weaknesses and leave the strengths intact are the most common route to funding on the second attempt.
