The ERC Starting Grant is one of the most competitive early-career awards in Europe, with success rates typically between 10% and 15% across panels. Since 2024, the evaluation is a two-stage process: an extended synopsis (Part B1, roughly five pages) is panel-reviewed first; shortlisted applicants submit the full proposal (Part B2) and defend it in an interview. This guide walks through the structural decisions that separate funded from shortlisted-but-rejected applications, drawn from published evaluation summaries and panel member feedback.
Start with the ground-breaking claim
The ERC evaluation criteria are weighted heavily toward "ground-breaking nature, ambition and feasibility of the research." Panels reject proposals that are incremental — even if the proposed science is well-designed and the PI is strong. Your first paragraph must state, in plain language, what paradigm you are challenging or what question has been unanswered. Do not bury this in methodology. If a reviewer cannot summarise your ground-breaking claim in one sentence after reading Part B1 once, the proposal is in trouble.
- •Lead Part B1 with a 3–4 sentence "high-risk / high-gain" framing, not with background literature.
- •Name the field-level assumption you are overturning. "We assumed X; this project tests whether Y is possible instead."
- •Panel reviewers read 10–15 proposals per round. Make yours memorable in the first 30 seconds of reading.
Structure of Part B1 (extended synopsis)
Part B1 is five pages (plus references) and must work as a standalone pitch. Panels decide shortlisting from B1 alone. A good allocation is roughly: half a page on the ground-breaking claim and why the timing is right, two pages on objectives and methodology, one page on preliminary results or feasibility evidence, half a page on risk mitigation, and half a page on the PI's track record framed around this project. Keep figures to 1–2 maximum in B1 — reviewers rarely zoom in.
The CV narrative: one story, not a list
The PI track record matters more than most applicants treat it. Your CV and achievements section should tell a single story that ends at this proposal. Every publication you highlight should trace a line toward the ground-breaking claim — do not list your best five papers, list the five that make this project inevitable. If you can show one counter-intuitive result from your past work that motivated the new direction, use it as the anchor. First-author or corresponding-author papers in top venues carry more weight than long co-author lists. Panels know the norms in your field; do not pad.
Risk, feasibility, and the "why now" question
ERC rewards genuine intellectual risk but punishes operational risk. The pattern to aim for: the science is risky (the result is uncertain) but the plan is feasible (you have the skills, equipment, and preliminary data to run the experiments). Every risky aim should be paired with a mitigation strategy or fallback experiment. Explicitly address why this work is feasible now — a new method, a new collaborator, newly available data — and not five years ago.
Preparing for the interview
If you are shortlisted, the interview is typically 10 minutes of presentation plus 15–20 minutes of questions with a multidisciplinary panel. The panel has already read the full B2. Do not re-summarise the proposal — spend 8 of your 10 minutes on the one experiment that best demonstrates the ground-breaking claim, and on what a successful outcome looks like. Practise answering: "What is the single most important result this project will produce?" and "What would make you abandon this direction halfway through?"
Checklist
- ✓Part B1 opens with a one-sentence ground-breaking claim on page 1.
- ✓Preliminary data shown in B1 supports the central risky aim, not the easy aim.
- ✓CV narrative highlights 5 publications that trace the arc to this project.
- ✓Every risky objective is paired with a mitigation strategy.
- ✓Host institution commitment letter is signed by a dean-level authority, not your direct PI.
- ✓Budget justification mentions each cost category — avoid "miscellaneous" or round numbers.
- ✓Interview slide deck spends 80% of time on one demonstrative experiment, not an overview.
- ✓Abstract is readable by someone in an adjacent panel (PE vs LS vs SH).
Applied in the last two years and got a B or C? Check the resubmission cooldown rules before you start — an A can resubmit next year, a B faces a one-year cooldown, a C faces two years across all ERC calls.
