My DS (19) is currently doing his Foundation at our local college, and is in the process of his Uni interviews to do Interior design/Interior Architecture.
He had to submit digital portfolios for Kingston and Nottingham Trent - Nottingham offered him a place on the basis of that (plus an essay about a building which inspires him), without interview, the other unis offered after interview. He has 4 offers so far, from Falmouth, Northumbria, Nottingham Trent and Sheffield Hallam and has his final interview this week at Kingston.
Some of his friends from school went straight to Uni to do art/design degrees, but he says this year at Foundation has really helped with the leap from school to Uni, helped him develop his creative thinking and drawing skills and just matured his approach all round. He has had a lot of help from his tutors on the Foundation course to put together a very professional looking portfolio.
Our thinking was that if he stayed at home, and did the Foundation year now (the course started before his 19th birthday) there were no tuition fees and it would be too good an opportunity to miss.
To get into the Foundation course (our local college is really well respected for its Foundation, which is a University of the Arts London qualification) he had to do an interview and present his work (he took along A leve and GCSE work, and work from outside school).
As he already has his A level results his uni offers just require him to pass the Foundation (though he is hoping for a Distinction). He has ABB at A level, with his A in textile art, but I think the standard offer for the courses he choose was 280 to 300 UCAS points.
