Lato sensu is a Latin expression that means "in a broad sense". It is used in other languages and areas such as Right, Linguistics, Semiotics and others, to refer that a given interpretation must be understood in its broadest, most comprehensive sense.
In Brazil, the expression was introduced to distinguish postgraduate courses of shorter duration as opposed to "stricto sensu".
"Lato sensu" designates the specialization courses and MBAs in which the research activity has a broad sense, involving specific problems in the area of study. The student receives a certificate of completion at the end of the course.
According to the MEC (Ministry of Education), postgraduate courses "Lato sensu" must have a minimum duration of 360 hours.
The longer postgraduate courses that include master's and doctoral degrees are designated by "stricto sensu" (in the strict sense). At the end of the course, the student receives the title of master or doctor.
Research carried out in specializations stricto sensu
they involve new problems and the proof of new theories. Unlike the lato sensu specializations that are aimed at solving new problems but applying existing theories.
