Headmaster shocked at teachers' grammar calls for new standards Another, a chemistry teacher, said he had been a "science teacher form (sic) more than 10 years" and repeated the phrase "I am also a keen sailor" three times. One addressed the headmaster as "Dear Mr Richard." He said: "These are serving teachers and this is really worrying. It matters because it shows there are people within the teaching profession who cannot write a letter or construct sentences. When you look at their qualifications, they have Cs, Ds and Es at A-level and third class degrees from not very reputable universities. You have people trying to teach the basics to children when they do not not themselves have a grasp of the basics. He added: "Ministers need to decree that teachers need a minimum of three Bs at A-level and an upper second-class degree in their subject before they are allowaed to teach. The alternative is what we have - thousands of teachers who do not know enough to teach children properly. A report last week ranked the UK 26th in international rankings on tests taken by more than 500,000 15 year-olds in maths, science and reading.
