I don't think I would want more on the NC tbh. I think there's too much on there already strait-jacketing teachers.
I work in an Academy in a tough area with high levels of deprivation. My son is highly able and very academic. What suits him and what suits some of the students we have at school is very very different, and there needs to be even more flexibility to allow for this.
Personally I would like students doing 'academic' routes to all do a GCSE in MFL.
I think most schools would do well to do more on managing personal finances and sex education still needs to be more relaxed and open in some schools.
I would drop IT from the NC as most students have the IT skills anyway, and IT teaching can be very poor IME. IT is a 'tool' for learning, not an end in itself, and should be used in all/most subjects anyway.
