For the international reader from the UK and the US and maybe other countries: college in Belgium is higher education after secondary school (high school) and you are only eligible to follow this with a full degree. In practice, this means you have had 6 years of primary school and 6 years of secondary school.
The degree is basically the only entrance requirement. Entrance exams are usually not required (there are exceptions as medical school etc…) but you will also not be allowed to follow classes without this degree. Even when you are brilliant and you’d pass the entrance exam, they would not allow you!
Belgian universities
There aren’t bad universities in Belgium. Whatever you choose is good. Good practice is to go for a known professor and that differs every now and then for every study direction.
Following some international lists the University of Leuven is the most prestigious followed by the university of Ghent. Those are indeed the two most famous universities in the country, but they wouldn’t dare to say they are better than the rest. Education in Belgium is strictly organized and the ministry of education submits quality control constantly.
Below a list of the universities in the country. The first name in bold is the international name of the university. The second name is the local name in the local language.
