Obviously proving it has been read and passing tests on comprehension should be a condition of taking or keeping any senior job paid from the public purse. (Starting with M.Ps) Then work down the pay grades. This is semi flippant, but truly, that level of ignorance is not acceptable. It is as though we have our country run entirely by and for Japanese speakers, on the assumption that everyone speaks, and is, Japanese.
Meanwhile, all teachers/lecturers and all students should have any qualification held conditionally pending confirmation, till they too have passed the test, with a final examination of "who is a real, full, human being, exactly equal to you?" The trick questions would be that those identifying as Bame would accept white English are the same as themselves, and everyone should accept that extremely old and extremely impaired of all ages are also equal. (The 'equality' parts of the online school lessons appear to assume a) racism can only ever be white against black and b) there is no such thing as ageism, while c) all aspects of disablism are dealt with by showing an extremely high functioning Downs syndrome actor)
