As someone who has recently completed a PGCE, I was interested in your report "Primary trainees scared of grammar" (September 21).
I think literacy tests for trainee teachers are a good idea - as long as the student has been properly trained before attempting the test. Given that many trainees have never been formally taught grammar, the onus is surely on teacher training colleges to provide proper tuition.
There are many good self-study books on the market. To any trainee teacher scared of grammar, I would wholeheartedly recommend an excellent and reasonably priced series of books called English Basics - practice and revision by Mark Cholij, published by Cambridge University Press.
Good textbooks and self-study are, however, only a partial solution. To allay unnecessary anxieties and to ensure that badly-needed teachers are not discouraged before they have even begun their career, teacher training colleges will need to direct more resources towards proper literacy - and numeracy - strategies.
