If you're planning to build a career with the United Nations, understanding the different UN job levels is essential. One of the most common questions candidates ask is what designations such as P, G, NO, FS, D, ASG, and USG actually mean.

Every vacancy published by the United Nations includes a job category and grade. These grades define the level of responsibility, required qualifications, salary range, and career progression opportunities. Choosing positions that match your experience is one of the most important steps in a successful UN job application.

This guide explains each United Nations job level, who can apply, typical responsibilities, and how these categories fit into long-term UN careers.

Why Understanding UN Job Levels Matters

Many qualified candidates are rejected simply because they apply for positions that do not match their experience level.

For example, applying for a P-4 position with only one year of experience is unlikely to be successful, while an experienced professional may overlook an appropriate P-2 or consultancy role.

Knowing the structure of United Nations job levels helps you:

• Apply for suitable vacancies.
• Understand salary expectations.
• Plan your career progression.
• Identify promotion opportunities.
• Improve your chances of being shortlisted.

Professional Category (P Levels)

The Professional (P) category is the primary international career path within the United Nations. These positions are open to applicants from all member states and usually require a university degree and relevant professional experience.

P-1

The P-1 level is designed for junior professionals with limited work experience. Vacancies are relatively rare, and many entry-level candidates instead enter through internships or graduate programmes.

Typical requirements:

• Bachelor's or Master's degree
• Up to two years of experience
• Strong analytical and communication skills

Ideal for:

• Recent graduates
• Young professionals
• Early-career specialists

P-2

The P-2 level is one of the most common entry points for international professionals.

Requirements generally include:

• Master's degree (or equivalent experience)
• Two to four years of professional experience
• Excellent English skills

Typical roles:

• Programme Officer
• Human Rights Officer
• Policy Analyst
• Information Management Officer

P-3

Professionals at the P-3 level are expected to manage projects independently and provide technical expertise.

Typical experience:

• Five years or more

Responsibilities include:

• Leading programmes
• Supervising small teams
• Developing policies
• Coordinating international projects

P-4

The P-4 grade is considered senior professional level.

Typical experience:

• Seven years or more

Responsibilities:

• Managing complex programmes
• Leading multidisciplinary teams
• Advising governments
• Representing the organization externally

P-5

The P-5 level is a senior management position.

Professionals often supervise multiple programmes, manage significant budgets, and oversee regional or global initiatives.

Most candidates have:

• More than ten years of international experience
• Strong leadership background
• Extensive technical expertise

General Service (G Levels)

The General Service (G) category consists of administrative and operational support positions.

Unlike Professional posts, G-level positions are usually recruited locally.

Examples include:

• Administrative Assistant
• Finance Assistant
• Human Resources Assistant
• IT Support Technician
• Procurement Assistant

These roles are ideal for candidates living in the country where the duty station is located.

National Officer (NO Levels)

The National Officer (NO) category is reserved for citizens of the country where the position is based.

Unlike General Service staff, National Officers perform professional-level work but focus on national programmes and local implementation.

Grades include:

• NO-A
• NO-B
• NO-C
• NO-D

Typical positions:

• Programme Specialist
• Education Officer
• Public Health Specialist
• Governance Advisor

Field Service (FS Levels)

The Field Service (FS) category supports peacekeeping operations and humanitarian missions.

These positions often require working in difficult environments.

Typical jobs include:

• Logistics Officer
• Security Coordination
• Supply Chain Management
• Telecommunications
• Engineering Support

Candidates should be prepared for frequent travel and deployment.

Director Levels (D-1 and D-2)

The Director (D) category represents senior leadership within the United Nations.

D-1

Responsibilities include:

• Managing large departments
• Leading strategic initiatives
• Supervising multiple programme teams

D-2

The highest career level before executive leadership.

Professionals at this level influence organizational strategy, global partnerships, and international policy implementation.

Executive Leadership (ASG and USG)

The highest-ranking officials within the UN system include:

Assistant Secretary-General (ASG)

ASGs oversee major divisions, regional operations, or thematic programmes.

Under-Secretary-General (USG)

USGs lead entire departments and report directly to the Secretary-General.

These appointments are typically made after decades of distinguished international leadership experience.

Consultant Positions

Although consultants are not assigned a P, G, or D grade, UN consultant jobs play a vital role in the UN system.

Consultants are hired for specialized expertise on fixed-term assignments and are often recruited for:

• Digital transformation
• Climate policy
• Public health
• Monitoring & Evaluation
• Research
• Artificial intelligence
• Governance

Consultancy positions are an excellent pathway for experienced professionals seeking flexibility.

Internship and Volunteer Opportunities

Students and graduates who do not yet qualify for Professional positions can begin their journey through:

• UN Internship Programme
• United Nations Volunteers (UNV)
• Junior Professional Officer (JPO) programmes
• Young Professionals Programme (YPP)

These opportunities help candidates gain valuable international experience.
