Hi Heather,
I've asked the same question twice now, over the past few months, but have had no replies. The only thing on the website in Assessment guidance - under 'Subject Specific Guidance' for 'Investigating Drawing'
, is the Learning Outcomes, but, as you say, no other information. Sorry I can't be of any more help, but I've been trying to find this out for some time - I hope you have more luck!
Gwen.
