Easy to say, harder in some circumstances to follow. I remember a former HoD of mine describing how despite having results that were well above every measure going, he still got a roasting from OFSTED for not implementing the National Numeracy Strategy, it was there in black and white in the report. It caused no end of problems for him with SLT. What on earth is 'NMP'? A 'former' manager at QCA, sounds a bit rich to be critical of anyone in officialdom, and quite amazing how these people never actually seem to go away, just they magically find jobs in some other quango. Yes, I agree totally, maths is maths and the basic skills required don't change. The point is that anyone looking to develop their scheme of work is now faced with a dilemma of starting it now and possibly having to re-organise a couple of years down the line. If your school/SLT allow you to simply ignore all official guidance then I'm ever so happy for you, sadly we don't all have that kind of luxury.
