One year, typically. Some could be two or have a big chunk of on-the-job training/internship.
We used to have a more prominent 3 year degree, but it went semi-extinct in favor of other intermediate education, leaving our Bachelor's equivalent being 4-5 years, depending on which degree you're going for. And yeah, I think now they made them all 4 year and have more of a master's offering.
The thing is that internationally those 4-5 year degrees are still the thing immediately under a masters' degree, so there is a bit of a mismatch there. That goes some ways towards clarifying that, thanks.
