What is a Seconded National Expert?
A Seconded National Expert (SNE) is a public-sector official from an EU member state, EFTA/EEA country, or in some cases a candidate country, temporarily placed at an EU institution under a tripartite agreement between the EU institution, the seconding administration, and the expert. The legal framework for SNEs at the Commission is Commission Decision C(2008)6866 of 12 November 2008, as subsequently amended; the European Parliament uses its own Bureau decision; the EEAS combines Council and Commission rules. SNEs are explicitly not covered by the Staff Regulations or by the CEOS. They remain part of the personnel of their seconding administration and continue to be paid their national salary. They are, however, fully integrated into the EU institution for the duration of the secondment: they work on EU files, attend internal meetings, are subject to the institution's professional conduct rules, owe duties of loyalty and confidentiality to the EU, and report to an EU line manager. The CEOS reference "Article 8a CEOS" that appears in some popular guides is in fact about other categories. SNE rules are set out in the standalone Commission/Parliament decisions rather than in CEOS itself.
How recruitment works
SNE recruitment is a two-stage process. The recruiting EU unit publishes an SNE vacancy notice describing the post (DG, unit, file, expected duration, required expertise, languages). The notice is sent to the Permanent Representations of the member states in Brussels, which forward it to the national administrations. National civil servants who wish to apply must obtain their administration's formal endorsement before submitting. It is the Permanent Representation, not the candidate, that officially nominates. Most national administrations run a small internal screening to choose between multiple interested staff before nominating one. Once nominated, candidates are shortlisted by the EU unit, typically via a competency-based interview (in person or by video) and a CV review. Successful candidates receive an offer letter; the secondment is then formalised through a tripartite agreement between the EU institution, the seconding administration, and the expert. The whole procedure typically takes three to six months from vacancy publication to start date.
Salary and benefits
Financially, an SNE is in an unusual position: they continue to receive their national salary from their home administration (this is the seconding administration's commitment), and on top of that they receive a daily subsistence allowance and a monthly subsistence allowance from the EU institution. The daily allowance is currently around €128 per working day in Brussels and Luxembourg, paid monthly in arrears; the monthly allowance is paid only to SNEs not entitled to the daily allowance (rules differ for SNEs whose home is in the duty country). On top, the EU institution covers a one-off travel and removal allowance, a daily subsistence supplement for missions, and access to the institution's canteens and internal services. SNEs are not on the Staff Regulations salary grid, do not accrue EU pension rights, and are not members of JSIS. Their health cover continues under their national social-security system, with EU support for emergency cover during missions. The economics work out well for SNEs from lower-pay member states and small for SNEs from high-pay member states; check the current allowance tables before deciding.
Career path and renewal
An SNE secondment runs for an initial period of typically six months to two years, renewable to a maximum total duration of four years (with a possible exceptional sixth year in some institutions). After the maximum is reached, the SNE must return to their seconding administration for at least six years before being eligible for another SNE post at the same institution. The secondment does not, in itself, create any right to a permanent EU position; many SNEs return enthusiastically to national civil service with greatly expanded EU expertise, while others use the secondment as a launchpad: SNE experience counts very strongly on EPSO competition CVs, opens informal networks for subsequent Contract Agent and Temporary Agent applications, and is often a prerequisite for senior national posts dealing with EU files. Some SNEs do convert into officials by passing EPSO during or shortly after their secondment; others move into agency Temporary Agent posts where their specific expertise is in demand.
Best fits and limitations
An SNE assignment is the right choice if you are a mid-to-senior national civil servant (typically 5-20 years of national administration experience), your home administration is willing to release you for two-to-four years while continuing to pay your salary, and you want a high-impact embed at the heart of EU decision-making. SNEs work on the most technical and politically sensitive files in their DG, often as the lead drafter on regulatory dossiers, briefings to the Commissioner, or negotiations with the Council and the Parliament. The honest limitations: you remain dependent on your home administration's goodwill (some are less supportive than others), the financial top-up is modest compared to a full Temporary Agent or Official salary, you do not accrue EU pension rights, and you must return home at the end of the maximum duration. SNEs in the EEAS work in a separate regime that includes posts in EU delegations worldwide. See [/guide/](/guide/) for a comparison with permanent staff categories.
