Blessed Thomas Holford actually got a grade 3 at its inspection last October. I do wonder what 'criteria' the Inspectors are using . Surely the school is doing outstandingly with both GCSE and A Level subjects.-
As I thought, you have conflated raw results and quality of education.
Imagine, for simplicity, two hypothetical schools.
One takes in 100 pupils who are all achieving at a level where their projected grades are all 8 and above.
One takes in 100 pupils who are all achieving at a level where their projected grades are all 4 and below.
At the end of their time in the school, 80 of the 100 in the first school get 8 or above. The remaining 20% get 6s and 7s, below the grades their ability on entry preficts
On the other hand, in the other school, 80% get 5s and 6s. The remaining pupils get 4s, as their ability on entry predicts.
Which SCHOOL has done better by its pupils? The first school, despite its high results, has meant that 20% of it pupils fell below the grades they should gave got. The second, despite its much lower results, taught 80% of its pupils to exceed the grades they shoukd have got.
Ofsted USED to be far too swayed by raw results too. In the most recent round of inspections, the framework looks much mire at what the school actually dies with its intake.
