The first thing we are going to do before entering fully into the definition of the postgraduate term is to establish its etymological origin. In this way, we have to determine that it comes from Latin and is the result of the sum of two parts delimited in a very clear and forceful way: the prefix post-, which is equivalent to "after", and the verb graduary, which can be translated as "graduating."

Postgraduate or postgraduate is the specialization study cycle that is taken after graduation or degree. It's about the training which follows the bachelor's degree, which is the degree of higher education obtained at the end of a four-year university degree.
It could be said that the postgraduate is the last phase of formal education and includes the specialization, master's and doctoral studies . The characteristics of postgraduates depend on each country or institution. There are postgraduate courses that last only a two-month period, while others may extend for more than one year.
A multitude of postgraduates are those that exist today throughout the world with the clear objective that any person can get the training they want, both for their personal enrichment and to be able to access a better present and future professional within the labor market.
Within the field, for example, of the masters we find the fact that the areas of knowledge where there are more alternatives of this type for the specialization of students are those of Law, Economics, Communication and Social Sciences or Engineering and Basic Sciences .
In this way, anyone who decides to do a master will find alternatives such as issues such as negotiation, human rights, the right of telecommunications and information technologies, energy consulting, mathematical engineering or Robotics and automation
For its part, no less wide is the offer in regards to doctorates. Thus, we have to underline the existence of a wide range of possibilities that revolve around areas such as electronics, humanities or the digital environment, among many others.
Postgraduate usually encourages the activities of investigation and the updating of university content, in addition to the specialization of knowledge . These courses offer the possibility to improve the skills acquired during university education.
Postgraduate courses are a tool for professional promotion . The fact of having a postgraduate degree can have a favorable impact when applying for a hierarchical or executive position in the increasingly competitive labor market.
The postgraduate also allows to transcend the generalist training granted by the undergraduate degree, which broadens the professional horizon. For example: a doctor can take a Master in Diabetes and specialize in said field of action. This professional, therefore, will have the necessary knowledge to excel in the treatment of this disease .
It should be noted that, although the university degree is usually an indispensable requirement to access postgraduate training, some institutions consider exceptions if the student accredits extensive experience in the professional field in question.
