Rank-in-post is a system by which staff are graded and paid for their expected contribution. Rank-in-post means that a serving staff member who is competitively selected for a post classified and budgeted at a higher level, for an expected period of one year or longer, is automatically promoted to that higher level immediately upon assumption of the higher level duties. There are no qualifying periods and no seniority requirements and no promotion bodies to recommend approval. Only candidates meeting the pre-defined requirements for a post as per the job description can be selected. Rank-in-post is based on standardized classification of jobs and transparent recruitment and selection processes, with oversight exercised by the relevant Compliance Review Bodies i.e. Compliance Review Board (CRB) or Compliance Review Panel (CRP) . Hiring units will be responsible for strictly complying with the corporate procedures on classification, recruitment, reassignment and selection, to ensure that only candidates with “the highest standards of efficiency, competence and integrity” as required by the Charter of the United Nations and who possess the right skills, experience and competencies required for the properly classified and budgeted posts are selected.
