DR John Sandall’s letter (ViewPoints, December 6), presumably in response to mine a week earlier, raises some interesting issues with which I should not necessarily disagree.

My proposal was that those obtaining third-class honours, were extremely likely to be deficient in some way, not necessarily thick.

Secondly, I wholeheartedly acknowledge that those with firsts do not always make the greatest teachers. One only has to contemplate so many university teachers, who are both professional and general disasters.

Thirdly, I read modern languages – chiefly literature and linguistics – a different kettle of fish from the technical disciplines he mentions, with respect to which I, to some extent, take his point.

Fourthly, having taught myself three of my A-Levels, two from scratch, one of my many shortcomings was being unable to comprehend not only why some of my pupils struggled, but also why they should need a teacher at all!

Perhaps Dr Sandalls would graciously accept that those with lower upper, or higher lower second-class honours, all else, being equal, make the best schoolteachers.
