They have an advanced diploma in Project Management.

PMI has this news on their website:

PMI’s Project Management Professional (PMP®) credential program earns ISO accreditation.

They also state they have 250,000 members in 160 countries.

Connections with a top university, ISO accreditation, and members world wide tells me this is the link you want to pursue.

There are distance learning courses available here as well, when it comes time to take more training.
