Hitting your MAG
Airfoilmod sir, with the greatest possible respect you are showing your age here .............
In most (state) schools today raw results, such as the attainment of say a Grade "C", do not repeat not, rate as "satisfactory" or anything else; hitting your Mininimum Attainment Grade ("MAG") just might.
The Ofsted concept these days is more subtle and target driven as a function of your achieving "Value Added" cf datum MAG - datum MAG usually being defined as a function of a statistically derived average points score at the previous Key Stage.
On a personal note, the perception today is that in school all must win prizes and this mechanism is pretty good at diluting simplistic achievment driven elitism.
Do not expect me further to defend the current system...........
