education in astrophysics, physics and mathematics, as well as in instrumentation and signal processing from the first year of university to the doctorate level. These programs lead to openings in the fields of research and high-tech industry. The OAMP organizes many astronomy outreach activities in order to share important discoveries with the public. The OAMP consists of two establishments: the Laboratory of Astrophysics of Marseille (LAM) and the Haute-Provence Observatory (OHP), along with the Département Gassendi, which is a common administrative and technical support unit. With over 50 researchers, 160 engineers, technical and administrative personnel, plus some 20 graduate students and post-docs, the OAMP is one of the most important research institutes in the region. Engineering Polytech Marseille is a Grande École d'Ingénieurs (Graduate School of Science and Engineering), part of AMU. The School offers 8 specialist courses in New Technologies which lead to an engineering degree after 5 years of studies. Polytech Marseille is also a member of the Polytech Group which comprises 13 engineering schools of French leading universities. Polytech Marseille's advanced level courses have a strong professional focus. They include compulsory work placements in a professional organisation. These programs also benefit from a top rank scientific environment, with teaching staff drawn from laboratories attached to major French research organisations that are among the leaders in their field. Students are recruited on the basis of a selective admissions process which goes via one of two nationwide competitive admissions examinations (concours): either after the baccalauréat (national secondary school graduation examination) for admission to a five-year course or after two years of higher education for admission to a three-year course. The courses are approved by the Commission des Titres d'Ingénieur (CTI), the French authority that authorizes recognised engineering schools to deliver the Diplôme d'Ingénieur (a state-recognised title, recognised equivalent to a "Master in Engineering" by AACRAO) and thus guarantees the quality of the courses. The courses are also accredited by EUR-ACE. Rankings and reputation In the 2015 Academic Ranking of World Universities (ARWU), AMU is ranked joint 101st–150th in the world. In the subject tables it is ranked joint 76th–100th in the world for Natural Sciences and Mathematics, joint 151st–200th in the world for Engineering/Technology and Computer Sciences, joint 101st–150th in the world for Life and Agricultural Sciences, joint 151st–200th in the world for Clinical Medicine and Pharmacy, 25th in the world for Mathematics, and joint 101st–150th in the world
