My previous advice on KS1 results is here:http://www.elevenplusexams.co.uk/appeal ... cation#b23
However, I notice that Bucks Review Panels are now requesting KS1 results on the headteacher's summary sheet.
What they're doing is checking whether the KS2 predictions look realistic in the light of everything that has been achieved previously.
For appeal purposes I think I would have been satisfied with year 5 levels to check that the child really is on target for level 5s.
I've noticed from reading various threads that panels will be expecting levels 3 at the end of KS1. My DS2 only achieved level: 2A Maths & Reading and 2B in writing. He was an April baby and only started full time school in term 5 (the then school policy) then the youngest in the year where kept back in reception only to join the rest of the year in year 2. Could this be used to explain why he didn't achieve level 3's?
Personally I would have thought so, especially if there was good progress from year 3 to year 5.
