These postgraduate programs with a duration longer than 18 months are usually master degrees and higher education courses designed for students, graduates and young professionals interested in a path that will lead them to a career in management or research. Not all boys and girls who have a bachelor 's or master's degree, are in fact willing to spend more than a year and a half - in some cases up to two years and beyond - for further specialization. These are therefore paths and courses for future managers or researchers who are often required specific skills that can only be acquired with training master programs of long duration.
