 To be able to deliver the engineering degree, an École Master 's curriculum has to be validated by the Commission des titres d'ingénieur (Commission of the Engineering Title).It is important for the external observer to note that the system in France is extremely demanding in its entrance requirements (numerus clausus, using student rank in exams as the only criterion), despite being almost free of tuition fees, and much stricter in regards to the academic level of applying students than many other systems.The system focuses solely on selecting students by their engineering fundamental disciplines (mathematics, physics) abilities rather than their financial ability to finance large tuition fees, thus enabling a wider population access to higher education.
