• other indirect costs (up to 20% of direct costs) that may be spent on costs that are related indirectly to the research project, including the cost of open access to publications and research data.

In the case of entities applying for state aid, indirect costs including indirect cost of Open Access and other indirect cost, must not exceed a total of 20 % of direct cost and the following categories of other direct costs are disregarded in the calculation of indirect costs: materials and small equipment, business trips, visits and consultations, collective investigators, and other.

Furthermore, during the project performance, the host institution must arrange with the principal investigator in the project for the distribution of at least 25 % of the funds arising from the other indirect costs actually incurred in the project.

NCN scholarships and doctoral fellowships are not available under PRELUDIUM.

If unreasonable costs are planned, a proposal may be rejected at the stage of eligibility check and merit-based evaluation.

Pursuant to the Open Access Policy, the research results should (if possible) be made available in open access.

The National Science Centre recognizes the following publication routes as compliant with its Open Access Policy:

1. publication in open access journals and on open access platforms registered, or with pending registration, in the Directory of Open Access Journals (DOAJ);
2. publication in subscription journals (in which the articles require payment of a subscription fee) and/or hybrid journals (in which some of the articles are open access and some require payment of a subscription fee); in the case of publishing in subscription-based model, it is advisable that Author Accepted Manuscript (AAM, i.e. the final manuscript version created by the author, including all the revisions introduced after the peer review, and accepted for publication in the journal; other terms: postprint or author’s accepted manuscript) or preprint, be made available in the repository listed in the Directory of Open Access Repositories (OpenDOAR); if the AAM/preprint is not made available, it will not affect the acknowledgment of expenses or the settlement of the project;
3. publication in journals covered by an open access licence within the framework of so-called transformative agreements (which are available within limited time in accordance with the applicable agreements between national publishing consortia; journals covered by Polish transformative agreements are listed on the website of the Virtual Library of Science.

Manuscripts must be published under the following licences:

• Route 1: Creative Commons (CC) licence or equivalent open licence in line with the open access policies;
• Route 2: Version of Record (VoR, i.e. manuscript version published in a journal with its own typeface and branding; other terms: published version or publisher’s pdf), AAM or preprint should be made available in the repository using CC licence or equivalent open licence in line with the open access policies;
• Route 3: CC licence or equivalent open licence in line with the open access policies.

Eligibility of Article Processing Charges:

The costs are eligible for each publication route and each CC licence or equivalent open licence in line with the open licence policies. NCN does not recommend incurring APC for articles published under Route 2, if the AAM or preprint can be made available in the repository at no charge.

The data underpinning scientific publications, whether in open or closed access, resulting from the project must be well-documented pursuant to the standards of the machine or manual findability, accessibility, interoperability or reusability (the so-called FAIR Data). Where possible, data must be made available in the repository using CC0 or CC BY 4.0 licence. Other licences can also be used as long as they ensure an equivalent level of data openness and reusability as CC0 or CC BY 4.0.

The term “data” is understood as data collected and unprocessed as well as data generated and analysed, other than scientific publications. The definition comprises all forms, both digital and non-digital.

All documents concerning proposals for state aid must be signed with a qualified electronic signature in the PAdES format.

Proposals are subject to an eligibility check and merit-based evaluation.

Eligibility checks are carried out by the coordinators. Only complete proposals that comply with the criteria set out in the call text can be accepted for a merit-based evaluation. A proposal may also be rejected as ineligible at the later stage of evaluation.

Proposals approved as eligible are subject to a merit-based evaluation performed in two stages:

Stage I: An evaluation is performed by the Expert Team formed by the NCN Council NCN, based on the short project description, information in the proposal and annexes thereto, with the exception of the full project description. Each proposal is evaluated by two members of the Expert Team acting independently. In the case of proposals which are assigned an auxiliary NCN review panel specifying disciplines covered by NCN review panels other than the one to which the proposal was submitted, the Chair of the Expert Team may decide to seek an auxiliary review from a member of another Expert Team (interdisciplinary proposals).

After the evaluation, the experts meet at the first Expert Team meeting. Based on the review of the proposals and discussions, a list of proposals recommended for Stage II of evaluation is compiled by the Expert Team.

Stage II: Proposals are addressed to at least two reviewers who draft individual reviews based on the full project description, information in the proposal and annexes thereto, with the exception of the short project description. Based on the reviews drafted by the reviewers and discussions at the second meeting, a ranking list of proposals recommended for funding is compiled by the Expert Team.

To find out more on the proposal evaluation procedure, please read the Proposal evaluation procedure for the Expert Team.

Proposals are reviewed within the panels to which they have been submitted (e.g. HS1, ST1, NZ1). The principal investigator selects the panel. The panel cannot be changed once the proposal has been submitted. We recommend that you precisely identify an auxiliary review panel as this may help to selects experts and reviewers for a merit-based evaluation of your proposals. The Chair of the Expert Team may decide that interdisciplinary proposals undergo an auxiliary review by an expert from another panel.

The evaluation of proposals focuses in particular on:

1. compliance with the basic research criteria;
2. scientific relevance, importance, originality and novelty of research or tasks to be performed;
3. impact of the project results on the development of the academic discipline;
4. assessment of the feasibility of the proposed project;
5. scientific achievements of the principal investigator and mentor;
6. assessment of other projects conducted by the principal investigator, funded by the NCN or from other sources;
7. relevance of the costs with regards to the subject and scope of the research; and
8. preparation of the proposal and compliance with other requirements set forth in the call text.

Proposals with a zero score or “no” decision agreed by the Expert Team in any reviewed criterion subject to an evaluation (except for the data management and ethics issues in research) must not be recommended for funding.

Proposals are evaluated by the Expert Teams within the review panels (i.e., HS1, NZ1, ST1) pursuant to the terms of the call and evaluation criteria laid down in the Regulations on awarding funding for research tasks.

Experts Teams are selected by the NCN Council pursuant to the terms of establishing and appointing Expert Teams. Experts are outstanding Polish and foreign researchers who are at least PhD holders. Expert Teams are established for each call edition. The composition of the Expert Team is subject to the number and subjects of proposals submitted to each panel.

The call results will be published on the NCN website and communicated to the applicant in the form of the NCN Director’s decision within 6 months of the proposal submission date, by the end of December 2026.

Please, read the Information for Applicants and Guidelines for applicants to complete proposals submitted to PRELUDIUM 25.
