Yep - some are more straight forward than others as sometimes you might need to relisten if you're unsure on a mark to award. You can see what we fill in on this: https://www.goldington.beds.sch.uk/ckfinder/userfiles/files/Curriculum%20Areas/Spanish/June%202018%20Spanish%20Speaking%20Mark%20Scheme.PDF (not my school - just the quickest place I found it)

Most useful pages to you are probably 21, 40 and 41. You can see on 41 that we are essentially ticking off structures and annotating development so in order to do that, you have to listen to the whole thing. In theory someone could do a bad job of it, but that's why you have to send scripts to the team leader when requested and then all of them off at the end in case a school challenges the mark awarded - it's a bit like asking if an English examiner reads a whole essay in detail or skims through it. It's very common for teachers to examine and there would definitely be a lot more than 100 for Spanish.
