The maximum number of continuing appointments to be granted in an exercise is calculated prior to the launch of each exercise. The number of continuing appointments is determined based on the continuing needs of the Organization as proscribed by the General Assembly in GA Resolution 65/247 on Human Resources Management. The continuing needs of the Organization are calculated on the basis of established and temporary posts of a duration of more than five years as well as general temporary assistance in special political missions (except for national staff recruited for field missions or international or locally recruited staff recruited for service in the ICTR or ICTY). The level of the post envelopes shall be reviewed regularly by the General Assembly.
