Training and access requirements vary depending on the CMS area you need to access. The overview below summarizes the minimum requirements for the most common CMS areas. For complete requirements, consult EDMS 2605306.
The following requirements apply to all CMS areas: Mandatory CERN trainings, a valid CERN ID card, and a mobile phone (recommended). The tables below summarize the additional requirements that apply on top of this baseline.
