Am I eligible for an MSCA Postdoctoral Fellowship?

The two rules that decide it (the 8-year research-experience limit and the mobility rule), explained with worked examples.

Updated Jun 20, 2026

Two rules decide whether you can apply for an MSCA Postdoctoral Fellowship: the 8-year research-experience limit and the mobility rule. Both are commonly miscounted, and getting either wrong means an otherwise strong proposal is ruled ineligible before it's even read. This guide explains exactly how each is calculated, with worked examples. Always confirm the precise wording in the current MSCA Work Programme.

The two gates

At the call deadline, you must:

  1. Hold a PhD (or have successfully defended your thesis, even if not yet formally awarded); and
  2. Have at most 8 years of full-time-equivalent research experience since your PhD; and
  3. Meet the mobility rule for your host country.

Miss any one and you're ineligible, so check all three before investing months in a proposal.

The 8-year rule, counted properly

The limit is 8 years of full-time-equivalent research experience, measured from the date your doctoral degree was awarded, not simply "years since your PhD." Several things do not count toward the maximum:

  • time spent outside research;
  • documented career breaks: parental leave, military service, long-term illness, clinical training, caring responsibilities;
  • for researchers reintegrating to Europe, research experience in third countries (for nationals/long-term residents of an EU or Associated Country).

Worked example. You were awarded your PhD 9 years ago, but spent 2 of those years on parental leave and non-research work. Your FTE research experience is roughly 7 years, within the limit. The raw "9 years since PhD" would have looked ineligible; the correct count is not.

Part-time example. Three calendar years of half-time research count as about 1.5 years of FTE experience.

Use the official tool. The European Commission publishes a self-assessment tool and detailed guidelines for the 8-year calculation. Miscounting this is one of the most common reasons applications are ruled ineligible. Run it before you commit.

The mobility rule, counted properly

You must not have resided or carried out your main activity (work, studies) in the country of your host for more than 12 months in the 36 months immediately before the call deadline.

Three things trip people up:

  • "Host country" is the beneficiary country for a European Fellowship, or the outgoing-phase host country for a Global Fellowship.
  • Both residence and main activity are assessed, each against the 12-month limit independently.
  • Count from the dates you arrived and left a country, which may differ from your contract dates.

Worked example. The 2026 call deadline is 9 September 2026, so the reference window is the 36 months before it (roughly September 2023 to September 2026). If, within that window, you spent 10 months in the host country, you're fine; 14 months would breach the rule, even if the rest of your career was elsewhere.

How the two rules interact

A useful way to hold them together: career breaks help the 8-year rule (they're excluded, extending your window), but they do not extend the mobility window, which is a fixed 36 months before the deadline. So a researcher with a long break may stay eligible on experience for years, while their mobility status can change call to call as the 36-month window rolls forward.

If both gates are clear and you hold your PhD, you're eligible, and the next step is the proposal itself, covered in our full MSCA-PF guide.

Draft this with Reservoir

Once you've confirmed you're eligible, keep your career in Reservoir and project it into the MSCA CV and the reusable sections of the proposal, so you spend your time on the science.

Frequently asked questions

How are the 8 years of research experience counted?

As full-time-equivalent research experience measured from the date your doctoral degree was awarded. Time spent outside research and documented career breaks (parental leave, military service, long-term illness, clinical training, caring responsibilities) do not count. For researchers reintegrating to Europe, research experience in third countries can also be excluded. Use the European Commission's self-assessment tool to get an exact figure.

Does part-time research count differently?

Yes, it's full-time equivalent. If you worked half-time in research for two calendar years, that counts as roughly one year toward the 8-year maximum. Periods that were not research at all do not count toward the limit.

What exactly does the mobility rule require?

You must not have resided or carried out your main activity (work, studies) in the country of your host for more than 12 months in the 36 months immediately before the call deadline. Both residence and main activity are assessed, each against the 12-month limit. The host is the beneficiary country (European Fellowships) or the outgoing-phase country (Global Fellowships).

I did a short stay in the host country. Am I disqualified?

Not necessarily. The limit is 12 months within the 36-month reference window before the deadline. A stay shorter than that, or one outside the window, does not breach the rule. Count from the dates you actually arrived and left the country, which may differ from your contract dates.

What if I had a career break?

Career breaks generally help eligibility, not hurt it: documented breaks are excluded from the 8-year research-experience count, effectively extending your window. The mobility rule, by contrast, is about a fixed 36-month period before the deadline and is not extended by breaks in the same way. Check the current MSCA Work Programme for the precise rules.

Do I need a PhD already?

You must hold a doctoral degree at the call deadline, or have successfully defended your thesis, even if the degree is not yet formally awarded. Without that, you are not eligible regardless of experience.
