The European Security and Defence College (ESDC) has opened applications for its 2027 internship programme, offering students the opportunity to gain practical experience within an EU institutional environment in Brussels, Belgium. The programme provides two internship periods in 2027 and is designed for students pursuing relevant bachelor’s or master’s degree programmes who want practical exposure to the European Union’s Common Security and Defence Policy (CSDP) and the wider Common Foreign and Security Policy (CFSP).
Selected interns will receive a monthly allowance of EUR 1,500, while eligible expenses for occasional duty trips outside Brussels may also be reimbursed. Applications must be submitted by 12:00 CET on 14 October 2026.
About the European Security and Defence College Internship
The ESDC is a European Union institution focused on education and training in the area of the EU’s Common Security and Defence Policy within the broader framework of the Common Foreign and Security Policy.
According to the official 2027 internship call, the programme is intended to give students an opportunity to work directly with the ESDC and contribute to the organisation and implementation of its activities. Through this practical experience, interns can develop a stronger understanding of CSDP and CFSP while applying knowledge gained through their academic studies.
The ESDC operates as a network that brings together civilian and military institutes, universities, academies and other organisations working in the fields of security and defence. Its activities therefore provide interns with exposure to a broad institutional and international environment.
The ESDC works under the overall responsibility of the High Representative of the Union for Foreign Affairs and Security Policy, while the European External Action Service (EEAS) supports the High Representative in carrying out responsibilities relating to the EU’s foreign and security policy.
For students interested in international relations, diplomacy, security studies, defence policy, European affairs and related disciplines, the internship provides an opportunity to gain experience in an environment directly connected to these areas.

What Will ESDC Interns Do?
The internship is designed to provide practical experience rather than purely academic exposure. Successful candidates will support the ESDC Secretariat and contribute to a range of activities associated with security and defence policy training and education.
The official call identifies several responsibilities that interns may undertake.
1. Support Courses, Seminars and Conferences
Interns will assist with the preparation, implementation and post-processing of ESDC courses, seminars and conferences.
These activities may take place in Brussels or abroad and focus on CSDP and the broader CFSP framework.
This means interns can gain exposure to the planning and delivery of institutional events involving stakeholders working in European security and defence.
2. Prepare Course Materials and Background Documents
Interns may be responsible for helping prepare:
- Course materials
- Background briefs
- Reports
- Supporting documentation
This responsibility can provide useful experience in policy research, institutional writing, briefing preparation and information management.
3. Provide Meeting and Administrative Support
Interns will provide logistical and administrative assistance for meetings involving ESDC bodies, topic-focused configurations and ESDC stakeholders.
They may also:
- Attend meetings
- Take meeting notes
- Help prepare meetings
- Support post-meeting activities
- Assist with coordination and follow-up
This aspect of the internship can be particularly relevant to students interested in diplomacy, international organisations, public administration, foreign affairs and policy coordination.
4. Support eLearning Activities
The ESDC also expects interns to support the revision of its eLearning modules.
This could expose interns to institutional digital learning content, training development and the review of educational materials.
5. Maintain the Annual Training and Course Catalogue
Interns may assist in maintaining the ESDC’s annual training and course catalogue.
This involves supporting the organisation and management of information relating to the College’s training activities.
6. Contribute to the ESDC Annual Report
Interns may also support the drafting of the ESDC Annual Report.
This can provide practical exposure to institutional reporting, information gathering, drafting and documentation.
7. Support Knowledge Management
Another important responsibility involves supporting the ESDC Secretariat’s internal Lessons Identified / Lessons Learnt and knowledge-management processes.
This component can give interns insight into how international institutions capture experience, document lessons and use organisational knowledge to improve future activities.
8. Proofread Documents and Draft Social Media Posts
The internship also includes communication-related responsibilities.
Interns may be expected to:
- Proofread institutional documents
- Draft social media posts
- Support the preparation of communications content
This makes the opportunity potentially relevant not only to security and international-relations students, but also to students whose academic backgrounds combine international affairs with communications, public information, digital media or related fields, provided their programme is considered relevant to ESDC activities.
Who Can Apply for the ESDC Internship 2027?
The ESDC has established specific eligibility requirements.
Applicants must meet all applicable eligibility criteria outlined in the official call.
1. EU Citizenship Is Required
Applicants must be nationals of a Member State of the European Union.
This is an important requirement for prospective applicants from outside the European Union. The official call does not establish general eligibility for nationals of non-EU countries.
Therefore, applicants from African, Asian, American, Middle Eastern or other non-EU countries would not meet the stated nationality requirement unless they are also nationals of an EU Member State.
2. Current Bachelor’s or Master’s Students
Candidates must currently be enrolled at an academic institution or university with a view to obtaining a:
- Bachelor’s degree;
- Master’s degree; or
- Equivalent qualification.
Their field of study must be relevant to the activities of the ESDC.
The internship is therefore aimed primarily at currently enrolled students, rather than applicants who have already completed their studies and are no longer enrolled.
3. Students Must Remain Enrolled Throughout the Internship
Applicants must remain enrolled at their academic institution or university for the entire duration of the internship.
This means applicants should carefully consider their expected graduation date before applying.
A student whose enrolment ends before the completion of the selected internship period may not satisfy this requirement.
4. Health and Accident Insurance
Candidates must have insurance covering sickness and accidents for the entire duration of the internship.
Applicants should therefore ensure that appropriate coverage will be available throughout their selected internship period.
5. Language Requirement
Applicants must have a thorough knowledge of at least one EU working language: English or French.
Knowledge of another language is considered an additional asset.
What Academic Backgrounds May Be Relevant?
The official call does not provide an exhaustive list of qualifying degree programmes. Instead, it requires candidates to be enrolled in a field relevant to ESDC activities.
Given the College’s mandate and the responsibilities listed in the internship call, potentially relevant academic areas may include fields connected to:
- International relations
- Diplomacy
- Security studies
- Defence studies
- European studies
- Political science
- Foreign policy
- International security
- Strategic studies
- Peace and conflict studies
- Public policy
- International law
- European affairs
- Related social sciences and policy disciplines
Applicants should rely on the ESDC’s official assessment of whether their particular academic profile is relevant rather than assuming that a specific degree automatically qualifies.
Selection Criteria
Meeting the minimum eligibility requirements does not necessarily guarantee selection.
The ESDC states that applicants will be assessed based on several qualifications, including:
- Academic achievements
- Academic profile
- International profile
- Work experience
This means applicants should present their academic and professional background clearly and demonstrate how their studies and experience relate to the work of the ESDC.
Students with relevant international exposure, academic projects, internships, research activities or work experience may wish to make those aspects clear in their application where applicable.
What Does the ESDC Internship Offer?
One of the most significant features of the programme is the financial allowance.
EUR 1,500 Monthly Allowance
Selected interns will receive a monthly allowance of EUR 1,500.
The call also explains how the allowance interacts with certain external grants.
For example, if an intern receives a grant such as an Erasmus+ grant, the ESDC will reimburse the difference up to the EUR 1,500 monthly amount.
Reimbursement for Certain Duty-Trip Expenses
Interns may participate in ESDC duty trips outside Brussels, subject to budget availability.
The ESDC states that interns will be reimbursed for expenses associated with occasional duty trips outside Brussels.
This provides an additional opportunity for selected interns to gain exposure to ESDC activities beyond the institution’s Brussels base.
Internship Mentorship and Responsibilities
Interns will be placed under the responsibility of a mentor.
They are expected to follow instructions provided by their mentors and ESDC superiors and maintain high standards of:
- Personal integrity
- Impartiality
- Courtesy
Interns are also required to keep a careful record of their activities and submit a report to their mentor at the end of the internship.
After completing the internship, the ESDC will provide a certificate confirming the internship.
Working Hours and Leave
Interns will work the same working hours as ESDC staff and will have the same official public holidays as ESDC employees.
They are also entitled to two working days of leave per month.
These provisions provide applicants with a clearer understanding of the institutional nature of the internship and the expectations associated with participating in the programme.
Equal Opportunities and Inclusion
The ESDC states that it is committed to an equal-opportunities policy for its staff and applicants.
The College says it is committed to:
- Promoting gender equality;
- Preventing discrimination on any grounds;
- Welcoming qualified candidates from diverse backgrounds; and
- Maintaining the broadest possible geographical representation among EU Member States.
Candidates with disabilities may request assistance or reasonable accommodation during the selection process.
The official call instructs candidates requiring accommodation to contact the ESDC vacancies address so that appropriate support can be considered.
Documents Required to Apply
Applicants must submit:
- A CV
- A motivation letter
The documents must be submitted in English or French and should be provided in PDF or Word format.
The ESDC specifically requests applicants to use the European CV format.
Applicants should therefore ensure that their CV clearly communicates their academic background, relevant experience, international exposure, language abilities and other information relevant to the internship.

Applicants must:
- Be currently enrolled at an academic institution or university;
- Be pursuing a bachelor’s, master’s or equivalent degree;
- Be studying a field relevant to the ESDC’s activities; and

Nationality and geographical eligibility
The opportunity is restricted to nationals of European Union Member States.

Conclusion
The ESDC Internship 2027 provides eligible students with an opportunity to gain practical experience within a European Union institutional environment focused on security and defence policy.

However, applicants must carefully note the nationality requirement: candidates must be nationals of an EU Member State, must remain enrolled in their academic programme throughout the internship and must satisfy the language, insurance and other eligibility requirements.
