A successful Horizon Europe proposal clearly demonstrates scientific excellence, a credible implementation plan, and measurable societal impact — all aligned with the specific call’s priorities. Evaluators score proposals across three core criteria: excellence, impact, and implementation, and a strong bid must perform well across all three to reach the funding threshold. The sections below unpack exactly what that looks like in practice, from structure and consortium to the most common pitfalls to avoid.
What makes evaluators approve a Horizon Europe proposal?
Evaluators approve a Horizon Europe proposal when it scores above the threshold on all three evaluation criteria: excellence, impact, and implementation. Each criterion is scored out of five, and most calls set individual thresholds of 3.0 or higher per criterion, plus an overall minimum. A proposal that excels in one area but underperforms in another will typically be rejected regardless of its total score.
Beyond the numbers, evaluators are looking for a proposal that reads as coherent and credible. The research question must be clearly defined, the methodology must be appropriate to the objectives, and the team must have the expertise to deliver. Evaluators read dozens of proposals per call, so clarity and logical flow matter as much as technical depth. Proposals that force the reader to search for answers to basic questions — what is being done, why it matters, who is doing it — rarely score well.
One factor that experienced applicants emphasize is alignment with the call text. A proposal that is scientifically strong but does not directly address the expected outcomes and impacts listed in the work programme will still lose marks. Reading the call text as a checklist and ensuring every expected outcome is addressed somewhere in the proposal is a discipline that separates funded bids from rejected ones.
How is a Horizon Europe proposal structured?
A Horizon Europe proposal is structured around two main documents: Part A, which contains administrative and budget information submitted through the funding portal, and Part B, the technical description of the project. Part B is the core of the application and is divided into three sections that mirror the evaluation criteria: excellence, impact, and implementation.
- Section 1 — Excellence: Covers the objectives, the state of the art, the methodology, and the level of ambition. This is where the scientific case is made.
- Section 2 — Impact: Explains the expected outcomes, how results will be disseminated and exploited, and how the project contributes to EU policy priorities and the broader innovation ecosystem.
- Section 3 — Implementation: Details the work plan, work packages, milestones, deliverables, team roles, and risk management approach.
Most calls also require a list of participating organizations and a description of the consortium’s capacity. Page limits apply to each section, and exceeding them means pages are simply cut off during evaluation. Writing concisely within the permitted length is not optional — it is a core skill in Horizon Europe proposal writing.
What are the most common reasons Horizon Europe proposals fail?
The most common reasons Horizon Europe proposals fail are poor alignment with the call text, an underdeveloped impact section, an unrealistic work plan, and a consortium that lacks the right mix of expertise. Evaluators consistently flag these weaknesses in evaluation summary reports, making them well-documented patterns rather than speculation.
Poor call alignment is the most frequent issue. Applicants sometimes write a proposal around research they want to do and then try to fit it to the call, rather than starting from the call’s expected outcomes and building the proposal outward from there. The result is a technically competent document that does not answer the question the call is actually asking.
An underdeveloped impact section is the second major failure point. Many research teams invest heavily in the excellence section and treat impact as an afterthought, producing vague statements about “raising awareness” or “contributing to knowledge.” Evaluators expect a concrete theory of change: who will use the results, how, and with what effect.
Work plans that are either too vague or clearly overambitious also trigger low implementation scores. A work plan that promises ten major deliverables in the first six months, or one that has no logical dependency between work packages, signals to evaluators that the team has not thought through the project in operational terms.
How should the impact section be written to score highly?
The impact section scores highly when it moves beyond describing research outputs and instead articulates a clear pathway from project results to real-world change. Evaluators want to see who the target users or beneficiaries are, what they will do differently because of the project, and how the consortium will make that happen through dissemination, exploitation, and communication activities.
A strong impact section is built around the call’s expected outcomes and impacts, which are listed explicitly in the work programme. Each expected outcome should be addressed directly, with a concrete explanation of how the project contributes to it. Generic language about “advancing the field” or “supporting EU competitiveness” without specifics will not score well.
The exploitation plan deserves particular attention. Evaluators want to know what happens to the results after the project ends. For technology-oriented projects, this means addressing intellectual property, routes to market, and which partners will take ownership of commercialization. For policy-oriented projects, it means identifying the specific decision-makers or regulatory processes the results are intended to inform.
Communication and dissemination activities should be targeted and measurable. Rather than listing generic outputs like “project website” and “scientific publications,” strong proposals identify specific audiences, channels, and timing — and explain why those choices are appropriate for reaching the intended users of the research.
What does a strong consortium look like in a Horizon Europe bid?
A strong Horizon Europe consortium brings together partners whose combined expertise covers all the scientific, technical, and operational requirements of the project, while also including the right stakeholder types to ensure results can be implemented and scaled. The consortium must be fit for purpose — not too large to manage effectively, and not so small that critical competencies are missing.
Evaluators look for complementarity, not duplication. Each partner should have a clearly defined role that draws on capabilities the other partners do not have. A consortium where every partner is doing essentially the same thing, or where one partner dominates the work plan while others play token roles, will raise questions about the project’s management logic and the fairness of the budget allocation.
Geographic and sectoral diversity matters in many calls. Horizon Europe actively encourages the participation of partners from widening countries — EU member states with lower research and innovation performance — and the inclusion of industry partners, SMEs, or civil society organizations where relevant to the project’s impact pathway. A consortium composed entirely of academic partners from a few high-income countries may score lower on impact if the call expects broader societal engagement.
Trust and prior collaboration history between partners is also worth considering. Evaluators cannot verify working relationships, but proposals where the consortium clearly has a shared understanding of the project’s goals — evidenced by a coherent work plan with well-distributed responsibilities — tend to score better than proposals that feel assembled rather than designed.
When should you start preparing a Horizon Europe application?
You should start preparing a Horizon Europe application at least six months before the submission deadline, and ideally earlier for large collaborative projects. The most competitive bids are rarely written under time pressure — they are the result of extended concept development, partner alignment, and iterative drafting that takes months to complete properly.
The preparation timeline typically breaks down into three broad phases. The first phase involves identifying the right call, reading the work programme in detail, and forming the core consortium. This is also when the central research question and impact logic should be developed before any writing begins. Rushing this phase is one of the most common reasons proposals lack coherence.
The second phase is drafting, which should begin at least three to four months before the deadline. Starting with the impact section and the work plan — rather than the excellence section — forces the team to define what success looks like before getting absorbed in scientific detail. The excellence section is then written to support those outcomes, rather than the other way around.
The third phase is review and revision, ideally including feedback from colleagues who were not involved in drafting the proposal. Internal reviewers who can read the document as an evaluator would — checking for clarity, coherence, and alignment with the call text — add significant value. For 2026 calls, this means building review time into the schedule from the outset, not treating it as an optional final step.
