i don't think there's any problem with teachers using stock phrases which they can cut & paste BUT they should be written to make sense, NOT just copied from govt speak.
mind you, now you know how the govt 'talks' to us - half the time i didn't have a clue what the latest govt babble was about, let alone how to 'cascade' it to my staff, disseminate it, and then make it pupil aware.
in 3 different schools i have helped put together a bank of phrases which could be used for the 'basics' e.g. x can spell confidently, and is able to use common spelling patterns to work out longer words (govt speak would have me using words like high frequency polysyllabic).
THEN we were expected to write out up to 50 words of an individual comment for each pupil.
whilst i accept that many jobs have a range of stresses, there aren't that many on equivalent pay to teaching that expect the long hours, have no tech. support (so if you want statements to work on a report, you spend your eve working out the software system 'for fun')and have up to 200 individual reports to write in just two weeks on top of your normal work mode.
sadly, it is also true that the employment systems, unions and 'culture' of teaching is that you don't get rid of staff, unless they are truly horrendous. i used to have to check reports for up to 300 pupils, and some staff just did their own sweet thing, and refused to make any corrections. management would then say 'well, we can't sack them' and the reports went out like that!
so, complain, and if you're a gov. ASK the head what systems are in place for staff who don't complete their jobs satisfactorily - perhaps the next training day should be spent on how to do reports, with time to get the systems sorted out.
and some subjects, like
