It employs 26,000 permanent employees (researchers, engineers, and administrative staff) and 6,000 temporary workers.
The National Committee for Scientific Research, which is in charge of the recruitment and evaluation of researchers, is divided into 47 sections (e.g. section 1 is mathematics; section 7 is computer science and control). Research groups are affiliated with one primary institute and an optional secondary institute; the researchers themselves belong to one section.
For administrative purposes, the CNRS is divided into 18 regional divisions (including four just for the region of Paris).
CNRS runs its research units either independently or in association with other institutions, such as INSERM or universities. In French these units are called laboratoires informally and unités de recherche in administrative parlance. They are either operated solely by CNRS (and then known as unités propres de recherche or UPR) or as mixed organizations (unités mixtes de recherche or UMR), respectively. Each research unit has a unique numeric code attached and is headed by a director (typically, a university professor or CNRS research director). A research unit may be divided into research groups (“équipes”).
