The United Nations Common System standardizes job grading and compensation across agencies like UNICEF, WFP, UNDP, WHO, and UNHCR. Positions are divided into three primary categories:
- General Service (GS / G-1 to G-7): Locally recruited administrative, logistic, clerical, and support roles.
- National Professional Officers (NPO / NO-A to NO-D): Locally recruited national professional positions requiring a university degree.
- International Professional (IP / P-1 to P-5 and D-1/D-2): Globally recruited specialist, managerial, and directorial positions.
2. National Professional Officers (NO-A to NO-D)
For Nigerian professionals looking to join the UN in-country, National Professional Officer roles represent the premier career pathway. Qualifications correspond to experience:
