Why Language Skills Matter
International organizations operate in diverse environments, from diplomatic negotiations to grassroots development work. Language skills can:
Fulfill official requirements in UN applications.
Enhance collaboration in multilingual teams.
Support communication with stakeholders and communities.
Give you a competitive edge in recruitment processes.
Many positions explicitly require proficiency in at least one of the UN’s six official languages, and some functions, especially field or liaison roles, may demand more.
The Six Official UN Languages
The United Nations has six official languages, and knowledge of one or more of these is a major advantage:
| Language | Why It Matters |
|---|---|
| English | Primary working language in most organizations. |
| French | Widely used in diplomacy, peacekeeping, and Africa-based roles. |
| Spanish | Key in Latin America-focused agencies and operations. |
| Arabic | Crucial for roles in the Middle East and North Africa. |
| Chinese | Valuable in multilateral diplomacy and growing UN influence. |
| Russian | Important in Eastern Europe and former Soviet regions. |
English and French are often required or highly desirable across many UN system jobs, especially in headquarters, regional offices, and peacekeeping missions.
Beyond the UN: Languages in Other Organizations
Many other international organizations follow multilingual practices:
European Union: Prioritizes EU member state languages, particularly English, French, and German.
African Union: Emphasizes Arabic, English, French, Portuguese, and Swahili.
Organization of American States (OAS): English and Spanish are key.
ASEAN: English is the working language, but knowledge of regional languages is a plus.
Regional language proficiency often enhances candidacy for roles with strong geographic focus.
How Language Proficiency Is Assessed
When applying to jobs in international organizations, candidates are usually asked to:
Self-assess their language proficiency based on reading, writing, and speaking.
Demonstrate skills during interviews or written assessments.
Submit language certificates in some cases (e.g., DELF for French, DELE for Spanish).
Working knowledge of a second or third official language is frequently listed as an asset—even if not required—making language learning a worthwhile investment.
Strategic Combinations to Consider
Here are some high-value combinations depending on your career goals:
| Region/Focus | Recommended Languages |
|---|---|
| Africa | English + French or Arabic |
| Latin America | English + Spanish |
| Middle East | English + Arabic |
| Asia-Pacific | English + Chinese or regional languages |
| Eastern Europe/CIS | English + Russian |
| Multilateral HQs | English + French |
Tools and Resources for Learning
If you’re ready to strengthen your language portfolio, consider:
Online platforms: Duolingo, Babbel, Coursera, and UN language programs.
University courses: Many institutions offer specialized language tracks for diplomacy.
Language immersion: Volunteering or working abroad is one of the most effective ways to gain fluency.
Conclusion
In the interconnected world of international organizations, language proficiency is far more than a line on your resume—it’s a strategic tool for communication, inclusion, and impact. Investing in one or more of the UN’s official languages can significantly expand your global career possibilities and prepare you to thrive in multilingual environments.
Whether you’re preparing for a UN role, an EU institution, or a regional development bank, mastering the right languages can be a game-changer.
