The senior leadership in a grammar school will not accept the submission of any controlled assessment that is below a student’s target grade. It does not much care how this is achieved, and its management and leadership are rated outstanding by Ofsted. This is an endorsement of institutionalised fraud.
The German assessments of a school near me (not in my village) are rewritten by the teacher, and memorised by the students for replication the next morning. The same text is recited for oral examinations. The students have been taught no grammar, so cannot compose a sentence for themselves. This is fraud, and a senior Ofsted official has said that it is so prevalent he can do nothing about it. Update: Two more cheating methods prevalent in controlled assessment, told to me on Monday by a teacher who had been encouraged to use them by management (he did not specify whether senior management or head of department - leaving material on the board, for pupils to copy from, and giving two to three times the allocated time for an assessment. Neither of these practices would be detectable under current Ofsted arrangements.
Meantime, one of the best German departments in the country has had its worst results in ten years, because it does not cheat.
Until we have honest exams, we cannot rely on any Ofsted report. In the meantime, these practices need to be exposed and rooted out.
This Secret Teacher article from The Guardian has a detailed view from inside a school. It is, of course, anonymous, but think of the professional consequences for the author if he or she had decided to sign it.
