ensIIE is a member of the Conférence des grandes écoles (CGE) and is affiliated with both the Université Paris-Saclay and the Institut Mines-Télécom.
ensIIE is one of the oldest computer science schools in France. It provides technical and scientific training based on the triptych of Computer Science – Applied Mathematics – Business and Finance, while maintaining close ties with industry and the corporate world.
ensIIE offers three types of Engineering Degree Programs:
An initial full-time program (FISE), primarily for students from Preparatory Classes for Grandes Écoles.
A work-study program (FISA), primarily for students from University Institutes of Technology (IUT).
A continuing education program (FC), primarily for professionals returning to higher education.
Students can be admitted to ensIIE through the selective Concours Mines-Télécom examination, after a strong competition during two years of undergraduate studies in classes préparatoires aux grandes écoles. The selection was done on the Concours Centrale-Supélec examination before 2015. Students can also be admitted through parallel admissions, coming from various IUT as well as multiplie faculties all around France, along with a number of international students through partnerships.
The school belongs to prestigious groups of institutions such as Institut Mines-Télécom, or University of Paris-Saclay (associate member).
The ensIIE Engineering School was created by the Conservatoire National des Arts et Métiers in 1968.
Initially located in Paris, it is now in Évry (France).
In 2025, the ensIIE benefits from a network of over 4900 alumni, engineers who have graduated from the school under any major or type of training.

History
Founded in 1968 by Paul Namian, a lecturer at CNAM, within the Conservatoire national des arts et métiers, the Institut d'Informatique d'Entreprise (IIE) was initially located in Paris, within the CNAM premises. The first student cohorts were very small, with no more than thirty students, but quickly expanded.
In July 2006, the institute became the École nationale supérieure d'informatique pour l'industrie et l'entreprise (ensIIE), and was established as a public administrative institution attached to the Université d'Évry-Val-d'Essonne.
From 2006 to 2008: Florent Chavand, Director.
From 2008 to 2018: Ménad Sidahmed, Director. During this period, ENSIIE gained expanded responsibilities and competencies (RCE).
Between 2009 and 2017, the school operated a satellite campus in Strasbourg, in Alsace. It hosted approximately 50 students per class but was closed due to lack of funding.
In 2015, the school joined the Télécom INT entrance exam, which later became the Mines-Télécom entrance exam following its merger with the Mines Schools Common Entrance Exam.
In 2016, a merger with Télécom SudParis was considered but was eventually abandoned.
In 2017, the school became affiliated with Université Paris-Saclay and the Institut Mines-Télécom.
Admissions
Students admitted to ensIIE may come from:
The Concours Centrale-Supélec, from 1974 until 2014 (preparatory tracks MP, PSI, PC, and TSI).
The score pool of the Mines-Télécom entrance exam since 2015 (Mines-Télécom Exam, preparatory tracks: MP – 65 seats, PSI – 18 seats, MPI – 15 seats, PC – 10 seats, and TSI – 2 seats).
The national DEUG exam – 2 seats until 2022.
Admissions based on academic qualifications for holders of a BUT / DUT, a BTS followed by a ATS preparatory program, a Licence degree, or any equivalent qualification in computer science or mathematics.
Admission into the second year is possible via academic qualifications, for holders of a Master 1 / Master 2 or an equivalent degree in computer science or mathematics.
Academic studies
Courses last 3 years, and the final year can be done in a foreign university, such as the University of Manchester (UK), Oxford University (UK), Aston University (UK), Université de Sherbrooke (Canada).
Some of these collaborations will enable the student to obtain both the ENSIIE degree and the master's degree of the host university.
There also exist multiple partnerships with other international universities that do not involve a double degree in which the students can take a part of. The full list can be found on the official website.
First-Year Core Curriculum
During the 1st and 2nd semesters, all students follow the same courses, organized into four major modules:
Digital Computer Science
Applied Mathematics and Quantitative Methods
Economics and Management, Entrepreneurship
Personal Development, Languages (Soft Skills)
These courses are designed to provide students with the scientific foundations and essential tools for their future careers as engineers. These core skills enable them to adapt to and keep pace with the rapid evolution of the digital world.
Tracks Starting in the Second Year

Internships
Students complete approximately one year of internship experience over the course of their studies, with one internship each year:
8 to 13 weeks in the first year (Programming and Development Internship)
10 to 13 weeks in the second year (Design and Development Internship)
5 to 6 months in the third year (Design, Technology Watch, and Innovation Internship)
International Dual Degrees
Foreign University
During the second or third year of studies, ensIIE offers students the opportunity to complete part of their education at a foreign university, often as part of a dual curriculum program, which can lead to obtaining a foreign degree, such as a Master of Science (MSc).
Dual Degrees in France
This dual degree aims to offer a select number of students high-level training, combining expertise in computer science (ensIIE) and telecommunications (Télécom SudParis), within two recognized public graduate schools, both located in Évry-Courcouronnes. Students complete at least 3 semesters in each school.
Upon completion of the program and subject to validation:
ensIIE Engineering Degree
Engineering Degree from Télécom SudParis – Institut Mines-Télécom Institut Mines Télécom, with a specialization in FISE or FISA depending on the chosen path.
Opening in September 2025.
After the first two years at ensIIE, students have the opportunity to complete their curriculum by spending two additional years at Institut Mines-Télécom Business School, to obtain a dual engineer-manager degree.
Students have the opportunity to follow the major "Innovation, Design and Committed Entrepreneurship" (IDEE) at the Institut Mines-Télécom Business School, Telecom SudParis, ensIIE, and the ESAD Reims.
In the first year, students can obtain a Bachelor's degree in Mathematics (L3) from Université d'Évry Paris Saclay. Each year, approximately 70% of first-year students enroll and obtain the degree.
In the second year, students following the Applied Mathematics track can simultaneously pursue the M1 in Applied Mathematics from Université Paris-Saclay.
The final year can also be part of a dual curriculum: some students may choose to take courses for a master's degree, in parallel with their studies at the school. Most often, this master's degree replaces the choice of one or more options in the traditional curriculum.
Research
A significant number of teachers at ensIIE are teacher-researchers, and thus have a research mission to fulfill.
The research teams associated with the school work on the following main themes: Stochastic control in finance, Combinatorial optimization, Program specification and verification, Statistical learning.
This work is carried out in laboratories associated with ensIIE.
