Three things decide whether a PTE score works for a university: which test, which version, and which number. Almost every university accepts PTE Academic; PTE Core is the Canadian immigration test and is not usually on an admissions list. In the UK the version matters as well as the score: a Student visa needs a Secure English Language Test, so international students usually sit PTE Academic UKVI, and the university then applies its own academic minimum, which is often above the visa floor. The number is set by the institution, and frequently by the course: an engineering degree and a nursing degree at the same university can ask for different scores.
The tables above give the figure the university publishes institution-wide where there is one. Where a university sets requirements course by course, the row says so, and the course page is the source.
