UN Grade Levels Explained: G, NO, P-1 to P-5, D-1 and D-2
By Mai Nazzal · Founder, StandbyRoster · Updated July 2026 · All guides
UN grades are eligibility gates, not seniority labels: General Service (G) roles are locally recruited, National Officer (NO) roles are reserved for nationals, and P-1 to P-5 and D-1/D-2 are internationally recruited. Each P grade carries a minimum-experience threshold — typically 5 years for P-3, 7 for P-4, 10 for P-5 — checked mechanically before anyone reads your achievements.
Applying one grade too high is the most common self-inflicted rejection in UN recruitment. Grades are not seniority labels — they are eligibility gates with specific minimum-experience thresholds, checked mechanically before anyone reads your achievements. Here is the system, and how to target the level your record actually clears.
What are the three UN staff categories?
General Service (G-1 to G-7). Locally recruited support and administrative roles, paid on local salary scales. G-6 and G-7 staff often carry substantial responsibility; the category describes recruitment basis, not capability.
National Officers (NO-A to NO-E). Professional roles reserved for nationals of the duty-station country, doing professional-level work with national context expertise. A strong NO track is a common route into international P posts.
International Professional (P-1 to P-5) and Director (D-1, D-2). Internationally recruited, expected to serve at any duty station. This is the category most international applicants target.
What does each UN P grade expect?
Typical minimums (agencies vary slightly; the vacancy text is always authoritative):
| Grade | Minimum experience | Typical role shape |
|---|---|---|
| P-1 / P-2 | 0-2 years (advanced degree) | Entry professional; JPO programmes sit here |
| P-3 | 5 years | Independent specialist; runs projects or components |
| P-4 | 7 years | Senior specialist or unit manager; supervises staff and budgets |
| P-5 | 10 years | Section chief or senior adviser; leads programmes and teams |
| D-1 / D-2 | 15+ years | Division or country office leadership; representation |
Experience counting starts after the qualifying degree, must be "progressively responsible", and must usually be relevant to the function. A first-level university degree with two additional years of experience is commonly accepted in lieu of an advanced degree — the vacancy states when.
How does UN pay work?
P and D salaries combine a published base scale with a post adjustment that varies by duty station's cost of living, set through the International Civil Service Commission (ICSC). Two P-4s in New York and Nairobi earn the same base but different totals. Benefits (dependency allowances, education grant, rental subsidies at some stations) sit on top; the vacancy or the agency's HR pages give current figures.
Which UN grade should you apply for?
- Count your post-degree years honestly, the way a screener will: from the employment blocks on your P11, with no double-counting of overlaps.
- Apply at the grade your years clear, not the one your ambition prefers. An excellent P-3 application beats a screened-out P-4 application every time — and P-3 to P-4 promotion happens; rejection records do not.
- Coming from the private sector or NGOs, your equivalent grade is usually one step lower than your instinct: a corporate "senior manager" title often maps to P-3, not P-4, because the UN counts relevant field years, not titles.
- Watch the fixed-term vs temporary distinction — temporary appointments can be a faster entry door at your true grade, and the internal-candidate advantage afterward is real.
