AST3 offers a route into the EU civil service for people with practical professional experience. The 2026 Data Management competition covers three areas, from statistical data to libraries and archives. Understanding the grade, the work and the recruitment process helps you decide whether this opportunity matches your background.
AST is the EU staff category for assistants. Its career structure runs from AST1 to AST11. The number 3 identifies the grade at which a person is recruited. Assistants carry out administrative, technical and operational work that helps EU institutions deliver their responsibilities.The word “assistant” can cover substantial specialist duties. Depending on the post, you may maintain information systems, check the quality of data, organise collections or support teams that need reliable records. Your precise responsibilities depend on the recruiting service and the vacancy.
EPSO/AST/158/26 establishes reserve lists for permanent officials at AST3 grade. The three fields are shown below. Applicants select one field.
This field supports the production and use of reliable information. Typical work includes preparing datasets, checking quality, maintaining metadata and producing tables or visual outputs. It may suit candidates whose experience involves handling data and supporting analytical work.
This field concerns organising information resources and helping users find them. Work may include cataloguing, managing collections and supporting information searches. Candidates should connect their professional experience to the specific duties and criteria in the notice.
This field concerns the organisation, retention and preservation of institutional records. Work may include classification, digital preservation and guidance for staff handling records. Reliable documentation supports continuity and access to institutional knowledge.
The published targets are 423 for data processing, analytics and statistics, 243 for librarianship and information science, and 298 for records and archives management — 964 in total. These figures concern places on reserve lists. Recruitment follows when institutions identify suitable candidates for available posts. The listed locations include Brussels, Luxembourg and Strasbourg.
Applicants need EU citizenship and two official EU languages at the required levels, C1 and B2. Education and relevant experience must satisfy the chosen field’s rules. Routes include relevant post-secondary qualifications with experience, or qualifying secondary education followed by six years of relevant experience. Check the exact qualification combinations, duration and relevance requirements in the official notice before applying.
The selection includes verbal, numerical and abstract reasoning, a field-related test and a free-text essay on EU matters. Prepare across all these components and follow the Candidate Portal for confirmed arrangements.
