Staff positions are grouped in two broad categories of occupations (the Professional and higher categories and the General Service category) and the hierarchy is expressed by grade levels within those categories. The grade level of each position is established based on the nature of duties and responsibilities assigned to it and the related skills, knowledge and experience required.
National professional officers are recruited locally to perform work that typically requires knowledge of the local laws, culture and tradition. Positions in this category are classified against the same classification standards applied to positions in the Professional and higher categories, and are subject to the same recruitment criteria for positions in the Professional category.
Positions are classified according to the classification standards developed by the International Civil Service Commission (ICSC). Positions in the Professional and higher categories entail work that are analytical, evaluative and conceptual duties, and typically require an advanced university degree (Master’s degree or equivalent) and relevant work experience. Work in the General Service category is procedural, operational or technical in nature and supports the execution of programmes. General Service positions require a minimum of secondary education and relevant work experience.
Human Resources by Grade
The Professional and higher categories, the General Service category and the National professional officers are abbreviated here to P, G and N respectively.
Every year CEB Secretariat surveys the human resources within each member organization and generates statistical reports. Statistics are a snapshot of staff as at 31 December of the reporting year. Organizations remain accountable for the figures provided.
Statistics are collected from 33 member organizations. Since 2006, figures reported for the United Nations also include staff in field missions administered by the Department of Peacekeeping Operations (DPKO). UN Secretariat submits data on behalf of UN-Habitat, UNEP, UNODC and UNCTAD. Therefore, figures for these entities come under the "UN" grouping.
Statistics exclude staff with appointments of less than one year. National Professional Officers (NPOs) are reported separately, but some charts include this category.
Errors & Omissions
No data was submitted by the United Nations in 2004. Data reported for ICAO in 2006 were those of 2005. United Nations data on Professional staff in receipt of dependency allowance and number of their dependent children was erroneously reported in 2011.
Staff categories, summarized here, are as follows: 'G' for General Service (levels G1 to G10); 'P' for Professional (levels P-1 to P-5, D-1, D-2 & UG) & 'N' for National Professional Officers (levels NO-A to NO-E).
Between 2006 and 2007, there was a staff contract reform during the 61th General assembly (ref. A/61/255). In 2007, the status of the field mission staff changed.
Terminology The designations employed do not imply the expression of any opinion on the part of the secretariat of the Chief Executives Board for Coordination (CEB) concerning the legal status of any country, territory, area or city.
