D.U.T. Réseaux et Télécoms

Computer Networking & Telecoms

A  2 year Undergraduate Course

The "DUT Réseaux et Télécommunications" (Computer Networking & Telecoms) is a French national undergraduate diploma for candidates with a Baccalauréat (equivalent to "A" Levels in Maths and Science).  It is a two-year course, consisting of approximately 35 hours per week. There is a strong emphasis on practical work. The course is divided into practicals (50% ), small group work (30%) and lectures (20%). Most importantly, there is a 3 to 5-month industrial placement which carries a high weighting in terms of the final grade.

The three main areas of study are Computer Science, Computer Networking and Telecoms.

An element of network security and cyber defence is built into a number of the modules.

Two year syllabus: 1800hrs

First and second year subjects:

Professional skills

Maths, Project management and oral and written communication in French and in English are considered important aspects of the course. These are intended to support and extend your academic and professional skills. They are taught in a practical way in small groups. The emphasis is on preparing you for a real working environment.


Tutor led projects (300 hrs)

Technical or scientific applications in groups supervised by a tutor. These are intended to extend the knowledge, application and analytical skills learnt during the course.


The internship period

The internship/work placement period is a compulsory and important part of the second year. It takes place at the end of the course for 10 to 12 weeks in an appropriate technical environment. There are opportunities to do this placement in France or abroad.



  • Apply concepts and skills learnt during the course  in an industrial/business environment
  • Learn appropriate professional and workplace behaviours
  • Experience how networks and telecoms companies and organisations work
  • Take responsibility for the rigorous completion of designated projects
  • Work independently and as a member of a team


When is the placement?

The placement is from April to the end of June, but may be longer if the student and placement provider so wish.
