Overmarking - Wisdom Applied.

Teachers with vested interest. Yorks Post.
From: Gerald Hodgson, Spennithorne, Leyburn.
Your article headed “Heads 
hit back at claims of over-marking” (Yorkshire Post, November 13) quotes the National Association of Head Teachers as saying that there is no evidence of teachers over-marking.
I suggest that there is no evidence because evidence 
is very hard to establish, but 
the fact is that teachers 
marking their own pupils’ 
work are put in an impossible position.
They clearly have a vested interest in the success of their pupils and they would be hardly human if this did not lead them to look favourably on their pupils’ efforts, especially in borderline situations.
In other walks of life, great efforts are made to avoid conflicts of interest.
In marking their own pupils’ work, teachers have an obvious conflict of interest which can 
only be resolved by a reversion 
to the situation which was in place for many years, namely an exam sat on a specific day and marked by examiners who have no idea whose papers they are marking.
