NCN is the acronym of Narodowe Centrum Nauki — the National Science Centre — Poland’s national grant-making agency for basic (fundamental) research. Established by the Act of 30 April 2010 on the National Science Centre and operating since 1 October 2010, NCN is headquartered in Kraków and is the country’s principal source of competitive, peer-reviewed funding for curiosity-driven research across all academic disciplines, from the humanities and social sciences to the natural sciences, engineering, and life sciences. If you encountered “NCN” in a grants-management or international-collaboration context involving a Polish partner institution, this is almost certainly the agency in question.
NCN vs. NCBR: basic research vs. applied research
Poland splits its national competitive research funding between two agencies with distinct mandates, and confusing them is a common mistake for administrators new to the Polish system:
- NCN (Narodowe Centrum Nauki) funds basic research — projects driven by scientific curiosity rather than a defined commercial or policy application, evaluated primarily on scientific merit and originality.
- NCBR (Narodowe Centrum Badań i Rozwoju, the National Centre for Research and Development) funds applied research and development, technology commercialization, and industry-linked projects. NCBR was established in 2007, three years before NCN.
A Polish research administrator’s first task when scoping a funding search is usually to identify which side of that line a given project falls on — the funding-council model generally, and this basic/applied split specifically, is a recurring pattern research administrators encounter when working with national grants management systems outside the US federal-agency framework.
Governance and funding source
NCN is a state legal entity (state governmental unit) funded through Poland’s national budget, operating under the oversight of Poland’s minister responsible for higher education and science, but with statutory independence over which specific projects it funds — decisions on individual grants are made by expert panels and the NCN Council, not by the ministry. This separation of political oversight from project-level funding decisions mirrors the arm’s-length model used by comparable national basic-research funders elsewhere in Europe, such as Germany’s DFG and the Dutch NWO.
Main flagship funding schemes
NCN organizes most of its funding around career stage and project scale rather than around discipline. Call editions are numbered sequentially and reopen on a recurring schedule (for example, “OPUS 29” or “SONATA 21”), so the specific numbered edition changes year to year even though the underlying scheme’s purpose stays stable. The core flagship schemes are:
- OPUS — NCN’s largest and most general scheme, open to researchers at any career stage. OPUS grants can fund a full research team (postdocs, PhD students on scholarships) and equipment, and — in some editions — has included an international co-funding module for projects run jointly with a foreign partner.
- PRELUDIUM — for researchers who have not yet been awarded a doctoral degree; the smallest and most accessible flagship scheme, intended as many applicants’ first independent grant.
- SONATA — for early-career researchers holding a PhD conferred within a defined recent window (historically around 2–7 years before the year of submission), supporting the transition to independent research leadership.
- SONATA BIS — for more experienced researchers (with a PhD but not yet a habilitation) who want to build and lead a new research team, distinguishing it from SONATA’s individual-investigator framing.
- MAESTRO — for experienced, established researchers with a substantial track record, intended for pioneering, higher-risk research projects.
Career-stage, mobility, and small-grant schemes
- ETIUDA — doctoral scholarships that typically include support for a research stay abroad as part of the doctoral project.
- MINIATURA — a fast-track, single-action small grant (for example, a preliminary study, archival query, short research visit, or conference trip) that does not require assembling a full research team or project proposal on the scale of the flagship schemes — designed to help researchers gather pilot data ahead of a larger application.
- POLONEZ BIS — an incoming-mobility fellowship scheme for researchers relocating to a Polish host institution from abroad, run in the tradition of MSCA COFUND-supported mobility programs; it is the scheme most relevant to a foreign researcher who wants to be the one holding the grant in Poland rather than a foreign collaborator on a Polish-led project.
International and bilateral collaboration schemes
Because a large share of NCN’s applicant pool works with international partners, NCN also runs schemes built specifically around cross-border collaboration:
- HARMONIA — for research projects carried out under formal international collaboration agreements or programs.
- Weave-UNISONO — Poland’s implementation of Science Europe’s Weave initiative, a shared review model that lets researchers in Poland and a partner country (for example, Germany, Austria, Switzerland, Czechia, or Slovenia, depending on the bilateral agreement) submit a single joint proposal reviewed once, rather than duplicating review in both national systems.
- DAINA — a bilateral scheme with Lithuania’s Research Council.
- GRIEG — a bilateral scheme with Norway, funded in part through the Norway/EEA Grants mechanism.
- UWERTURA — support for researchers preparing to apply to the European Research Council (ERC), intended to strengthen a Polish-based applicant’s competitiveness for ERC funding rather than to fund the underlying research project itself.
NCN periodically retires and introduces schemes, and exact eligibility windows, budget ceilings, and open dates change with each numbered call edition — administrators should always confirm current terms against the specific call documentation on ncn.gov.pl rather than relying on a general description, including this one, for a live application.
Eligibility: who can apply
NCN grants are held by a principal investigator based at an eligible host institution — a Polish university, research institute of the Polish Academy of Sciences, or other qualifying research entity — that formally administers the grant and employs or hosts the funded researchers. A foreign researcher who is not relocating to Poland typically participates as a partner or collaborator on a Polish-led project (for example, under HARMONIA or a bilateral scheme) rather than as the grant holder; POLONEZ BIS is the main route for a foreign researcher to become the Poland-based principal investigator themselves. As with most European national funders, nationality of the PI is generally not restrictive — what matters is that the PI is affiliated with, and the grant is administered through, an eligible Polish host institution.
Application process and review
Calls for the flagship schemes reopen multiple times a year on a published annual schedule, with each edition assigned a sequential number. Applications are submitted through NCN’s electronic system (OSF, the Online Grant Application Support System) and evaluated by expert panels organized into three broad panel groups covering the humanities/social sciences/arts, life sciences, and physical sciences/engineering, each further divided into discipline-specific panels. Review typically combines written assessment by panel members and external reviewers with a ranking process; some schemes (generally SONATA BIS and above) also include an interview stage for shortlisted applicants. Funded projects appear on published ranking lists by panel and scheme.
Indirect costs and budget structure
Like most national funders, NCN grants distinguish direct project costs (personnel, equipment, materials, travel, subcontracting) from a contribution toward the host institution’s indirect costs (overheads). The applicable indirect-cost rate and how it is shared between the grant and the host institution are set out in each call’s specific funding regulations and vary by scheme — a Polish grants office can confirm the exact figure and cost-sharing terms for a given call edition, and this is a point worth clarifying early with the host institution’s research support office rather than assuming a single fixed percentage applies across every NCN scheme.
Why this matters for international research administrators
NCN comes up for non-Polish research offices in a few recurring situations: coordinating a joint Weave-UNISONO or HARMONIA submission with a Polish partner institution, advising a researcher considering a POLONEZ BIS move to a Polish host institution, or simply distinguishing NCN from NCBR when a Polish collaborator mentions “national funding” without specifying which agency. Because NCN’s flagship schemes (OPUS, PRELUDIUM, SONATA) map roughly onto the career-stage logic used by comparable funders — general/open, pre-doctoral, and early-postdoctoral, respectively — administrators already familiar with schemes like DFG’s Emmy Noether Programme, the Irish Research Council’s career-stage awards, or Israel’s ISF personal-grant structure will find the underlying logic familiar even though the Polish names and numbering are distinct.
Frequently asked questions
Is NCN the same as NCBR?
No. NCN funds basic (fundamental) research; NCBR (National Centre for Research and Development) funds applied research and development. They are separate agencies with separate calls and separate budgets.
Can a researcher outside Poland apply directly to NCN?
Generally, an NCN grant must be held by a principal investigator based at an eligible Polish host institution. A researcher based abroad usually participates as a project partner on a Polish-led grant, or applies to relocate to a Polish institution under a mobility scheme such as POLONEZ BIS in order to become the grant-holding PI.
What is the difference between SONATA and SONATA BIS?
SONATA is aimed at early-career researchers a defined number of years past their PhD, typically running their own individual project. SONATA BIS is aimed at somewhat more experienced researchers (pre-habilitation) who want to establish and lead a new research team, which is a different scale and purpose than SONATA’s individual-investigator framing.
What is Weave-UNISONO?
Weave-UNISONO is NCN’s implementation of Science Europe’s Weave initiative: a joint bilateral or multilateral review procedure that lets researchers in Poland and a partner country submit and have reviewed a single collaborative proposal, rather than each side submitting separately through its own national process.
Where can I find the current NCN call schedule?
NCN publishes its annual call calendar and the specific terms for each numbered call edition (for example, OPUS 29, SONATA 21) directly on ncn.gov.pl, which is the authoritative source for current deadlines, budget ceilings, and eligibility details rather than any third-party summary, including this guide.
