On the "ask a gran" thread about bribing for exam results, I wrote about how privileged I was to have a family who delighted in learning & to whom it never occurred that bribery was an option.
My 4 children are 7 years apart & all went through the same local school comprehensive system just as all the testing beloved of Thatcher was being introduced. The first had none & the last got them all, and I watched their delight in school decreasing as more tests & teaching to tests became the norm.
Although my education was very old-fashioned, testing was for us to see how we were getting on and to be helpful at a personal level, not to be published for outsiders to comment on.
A colleague of mine asked to withdraw her child from SATs as she was getting upset and they co-incided with the first anniversary of her sister's death. On being refused, mum allowed her to be "off sick" (not ideal). On returning to school she was put in a room and given the papers to do. She was of course, a clever child & they wanted her in their stats! On hearing this story, another colleague told me quietly that she had been asked to keep her (struggling) child off sick that week - she too was upset.
This school had a supposedly "good" reputation locally, and when I heard people talking about it, wished I could tell them, but could not of course tell tales told to me confidentially.
