"University-level education - third stage" isn't a universally standardized term. The terminology for higher education levels varies across countries and even within countries. However, it generally refers to
doctoral or postgraduate research degrees, often leading to a PhD (Doctor of Philosophy) or similar advanced research qualifications.
This third stage follows:
* First stage: Undergraduate studies (Bachelor's degree)
* Second stage: Postgraduate taught studies (Master's degree)
Therefore, the "third stage" is dedicated to original research and the creation of new knowledge, culminating in a significant contribution to the field of study.
