ERC resubmission rules can affect whether a researcher is eligible to apply in 2027 based on results from earlier ERC calls.
For the 2027 Starting, Consolidator and Advanced Grant calls, the ERC states that applicants who received a C score at Step 1 in the 2025 or 2026 StG/CoG/AdG calls are not eligible, and applicants who received a B score at Step 1 in the 2026 StG/CoG/AdG calls are not eligible.
The ERC also limits applicants to one proposal under the 2027 Work Programme, except where the first submission is declared ineligible.
Because these rules can depend on the exact call and outcome, applicants should always check the current Work Programme and official eligibility guidance before submission.

Check eligibility before investing heavily in the draft
The first task is administrative but important.
Collect:
- the year of any previous ERC application;
- the grant scheme;
- the stage reached;
- the score or outcome;
- whether the proposal was eligible, ineligible, withdrawn or otherwise not evaluated.
Then compare that record with the 2027 Work Programme.
Do not rely on memory or a rule from a previous call year.
Resubmission rules create a timing decision
The ERC has explicitly encouraged researchers to consider whether their idea is mature enough before submitting.
That is good advice even without restrictions.
With resubmission rules, the cost of submitting a proposal too early can be higher because an unsuccessful Step 1 outcome may affect eligibility in a later year.
The relevant question is not:
Can I technically submit this year?
It is:
Is the scientific idea mature enough that this is a good year to use my application opportunity?
Maturity is not the same as having every detail solved
A proposal can be mature while preserving scientific uncertainty.
Maturity means:
- the central question is clear;
- the scientific importance is visible;
- the hypothesis or proposition is coherent;
- the objectives form one programme;
- the PI's independence is credible;
- the project has enough methodological logic to be executable;
- the field-level payoff can be stated without exaggeration.
It does not mean the answer is already known.
A previous rejection can be useful scientific information
If you are eligible to resubmit, do not begin by editing sentences.
First ask what changed in your understanding of the proposal.
A serious revision may require:
- a sharper scientific question;
- a larger or more coherent vision;
- a different panel;
- clearer PI independence;
- reduced methodological overload in Part I;
- stronger scientific optionality;
- a better connection between preliminary evidence and the unknown;
- a different team architecture.
The revised proposal should not simply be the previous one with reviewer comments patched in.
Distinguish proposal weakness from idea weakness
Sometimes the underlying science is strong but the proposal did not make it visible.
Sometimes the writing is clear and the scientific concept itself needs work.
A useful diagnostic is:
Proposal problem
The question is strong, but the argument is buried, the panel fit is poor, the figures do not clarify the concept, or Part I reads like a methods paper.
Scientific-concept problem
The project is incremental, the main result is already predictable, the objectives do not resolve a central uncertainty, or the field-level payoff is weak.
The second requires more than editing.
One proposal in 2027 increases the value of choosing carefully
Researchers who are eligible for more than one ERC scheme under the 2027 Work Programme still need to choose one proposal.
That means the submission decision should consider:
- scheme fit;
- scientific maturity;
- track record;
- previous ERC outcomes;
- call timing;
- whether another year would materially strengthen the programme.
Submitting because a deadline exists is not a strategy.
A practical resubmission review
Before deciding to submit again, ask:
- Am I eligible under the current 2027 rules?
- What was the real reason the previous proposal was not competitive?
- Has the central scientific question changed or matured?
- Is the new version a genuine scientific revision rather than an editorial revision?
- Does the panel choice still make sense?
- Is my PI profile stronger in a way that matters for this programme?
- Would waiting another call materially improve the scientific case?
A resubmission is most useful when the proposal has learned something.
