Growing up nowadays, I've had ICT lessons more or less as long as I can remember (started around year 1/2, aged about 5/6) and those were mainly a mixture of Office and various touch typing programs. Having a dad working in IT and a house full of computers has meant that I pick all of it up far quicker than the majority of my classmates, and so I soon got bored of "let's make Christmas cards in Publisher" etc. but there was nothing else in the curriculum at that point.
Around year 7 my school started this "Digital Creator" course from the BCS (quick google, looks like it's no longer offered by them). This was basically four units: audio, video, photography and sharing media (CDs etc). It was outdated from the start and very, very simplified. I found it pretty boring as it was mostly filling in worksheets and had very little actual computing or creative skill involved.
In year 9 we finally started actual coding and programming, in HTML/CSS, Small Basic, AppInventor (barely programming, I know, but better than Office) and also some Flash animation/ActionScript. This was the most interesting thing we'd done so far, but I still didn't love the subject, and then at the end of year 9 I dropped ICT/Computing entirely at GCSE. My friends who carried on are currently doing Python I believe. Unfortunately I have never really had the patience to get good at a language, and maybe dropping the subject is something I'll regret; then again, there are so many sites online on how to learn that I'm sure I can pick one up if I choose.
Personally I think that coding needs to be integrated into the curriculum FAR earlier than year 9, and taught in a way that interests more than the "geeky" kids. Making a program that prints prime numbers can't really compete with thermite in the science lab for example, but show people something like a robot or a game and they'll be far more interested.
Also, somewhere around year 7 the classes need to be set into the kids who can use Office and the ones who can't. It's hard for a teacher to try and get kids writing webpages in CSS when some of them still can't crop a picture in word (true story from year 9

)
Maybe once they achieve basic competency in Office they should get a certificate? Then there's no need for a GCSE to prove it.
TL;DR : Teach them Computing and how to code, because if they can't use Word by year 10 then there are bigger issues than the lack of an ICT GCSE.
