* The country: Admission requirements vary significantly between countries.
* The type of diploma: A diploma in a relevant field might allow for advanced standing (credit transfer), reducing the overall time and cost of the degree. A diploma in an unrelated field might require completing the full degree program.
* The university or institution: Each university has its own admission policies and may require specific prerequisites or entrance examinations.
* The type of degree: Some degrees might have more stringent entry requirements than others.
In short, while it's generally possible, a diploma holder should research the specific admission requirements of the universities and programs they are interested in. They may need to provide transcripts, take entrance exams, or complete bridging courses to meet the requirements.
