We also had revision sessions in each holiday (I refused to offer them), were expected to offer after school revision sessions despite the fact the students did not get study leave, so were essentially revising non-stop until their very last exam in every lesson. I have also recently been told that I am expected to start running some intervention sessions at lunchtimes, and we are meant to ring home to ensure the students attend!!
The pressure on students is enormous; I had a very interesting chat with a guy who works at our school in a pastoral / student support role part time and said the number of cases of anxiety, eating disorders and self harm in Year 10 and Year 11 seemed to have gone up since I started teaching seven years ago. He agreed with me, and we both thought constant levelling, assessment and increased pressure probably played a role in this. I realise this is just anecdotal, and there are other pressures (the internet glamourising some of the above for example) that may have also led to this increase, but I do think what we are fundamentally doing is putting pressure on the students.
Last year I had a fairly pleasant group of Year 11 students who were set 2 and quite an able bunch, all relatively academically-minded and all A-C targets. When I was asking what their future plans were for next year, around a quarter wanted to do A-levels, the rest all wanted to do other things (which I am not criticising at all). Some of the girls were going to college to do art, hair and beauty, one girl (who got loads of A's in the end) wanted to do an apprenticeship in an office, one boy (who had really high targets and did fairly well) has now taken a job as a caretaker in a school and is really enjoying it, one boy (who was phenomenally bright) got a job in a garden centre, one boy was dead set on joining the army, one was going to do an apprenticeship in plumbing. Of this quite bright and capable group about a quarter of them wanted to go on to do A-levels, the rest were all choosing alternative paths to do something else. I am not slating their choosing alternative paths in the slightest, I've heard most of them are getting on really well and am absolutely delighted for them, but I do worry that we're ultimately switching many of them off academic education at post-16 because of the hoops they have to jump through at school. The girl who wanted to do the apprenticeship in an office openly told me she'd had enough of school, and quite frankly I didn't blame her one bit!!
