But using Y6 SATS results as a way of predicting GCSE results is incredibly flawed, as my DD proves.
Y6 SATS, she didn't achieve a lvl. Mostly because she was still working on p-scales. Her GCSE predicted grades are now done the old-fashioned way, because she made so much progress in Y7 and Y8 once the Secondary actually gave her decent help with her SN's that the computer generated ones bear no relation to where she is working now in Y10!
According to the computer generated GCSE grade predictions, my DD will get U's in every subject. According to the teacher predictions (who h I trust FAR more!), she will get G-D, mostly D's and E's, depending on subject, and may just scrape a 'C' in Science.
Why use results from a test at 10/11 to determine what GCSE grades a 16yo is likely to get?! It's quite plausible for a DC to have a major developmental leap between 11 and 16.
What was wrong with teacher predictions, like when I was at school? They were usually spot on.
Or DC's that have unsupported SN's at Primary level being far better supported at Secondary level, thus rendering their SATS results useless for the purpose of GCSE grade prediction...
I trust DD's teachers to know what level she is working at now than some computer program that thinks that her achievement at 11yo will be able to predict her GCSE grades at 16yo!
