The National Technological University (Spanish: Universidad Tecnológica Nacional, UTN) is a National University of Argentina, specializing in engineering and exact sciences. Hosting over 75,000 students, its student body is comparable to Argentina's third-largest university (the National University of La Plata) and exceeded significantly only by the University of Buenos Aires (UBA) (over 300,000 students). Its 29 branches are located around the country. The engineering programs taught at most of those locations are: Students completing a five calendar-year program (typically after passing 45 final exams) earn an Ingeniero degree. All of the programs includes the same engineering fundational courses in Calculus (I, II), Physics (I, II), Algebra and Geometry, Probability and Statistics, Chemistry, Engineering and Society, Economics and Law. The curriculum has been going through a modernization focused on analytic programs ("adecuación curricular"), and in 2004, UTN had twenty-four thousand students in Information Systems; some careers have passed through a certification process ordered by the government. Research and Development is conducted in 18 official centers.
