NTU is one of the largest universities in the country, with more than 28,000 students. It has a diverse international community, with students from over 100 countries. Courses are spread over three campuses: one in the city centre, another four miles away in Clifton, and a third in the Brackenhurst countryside, about 14 miles out of town. The university has close links with more than 6,000 employers across the world; most courses are vocational and many students spending up to a year on work placements. The employment rate is excellent, with 94% of graduates employed or in further study six months after leaving. NTU has invested more than £350m in its three campuses over the past decade. This includes £90m on the regeneration of two grade II listed buildings, Newton and Arkwright, at the heart of the City site. This development has won multiple awards from the Royal Institute of British Architects. Their green-estates strategy has also helped them rank as the most environmentally friendly university in the country. Accommodation All new students who have NTU as their first choice are guaranteed an offer of university-allocated accommodation as long as they book by the 31 July. Self-catering accommodation ranges from £83.13 per week for a twin room to £152.60 per week for a studio. Facilities Recent developments include a sports centre endorsed by golfer Lee Westwood; the Rosalind Franklin building, a multimillion-pound chemistry and bioscience teaching facility; new libraries; and 24-hour computer rooms. By September 2013, there will also be a brand new student union building with bars, shops and a 2,000-capacity music venue. Transport The city centre is easily accessible due to the great rail, tram and road links, and an award-winning Unilink bus service between City and Clifton campuses. East Midlands airport is nearby, offering cheap flights across Europe. The university runs a popular cycle hire scheme across all three campuses.
