Coaches for CEA personnel

Nearly forty regular coach lines providing transportation for CEA personnel serve various “portes” (city gates) in Paris and most of the Paris suburban districts.

The personnel is dropped off at 8h30 at the roundabout on the RD306 (East entry, 200 metres from the INSTN), or within the confines at the bus station where shuttles run to the INSTN (5-minute journey). In the evening, these coaches can only be used when a training course or session ends at 4.30 pm.

The timetables and routes of these coaches are obtainable from the teaching assistants or the continuing professional development organizers.
