Now the system has expanded to include more courses in a broader range of fields. Curricula are advanced, intensive, practically oriented and designed to meet the expectations of students seeking specialized knowledge. The courses combine theory with practice in real or simulated work situations. These are the main characteristics of the more than 500 international courses now on offer at various levels. Each year over 5,000 students enrol in these courses, which last from a few weeks to four years.
Most courses lead to a diploma and a number of the longer courses result in a master s degree.
All of the regular universities award doctorates.
