I find some of the posts in this thread deeply worrying. I would expect and insist that my child's school report both raw test results (maybe as %), NC levels if available, and likewise, if available, standardised scores. The SS at least give you an objective measure of how your child is doing for their age compared to their peers, and the NC levels tell you where they are absolutely in relation to UK goals for various age groups.
I would also expect to see my child's teacher's own professional assessment taking into account all of my child's work, as this would provide some valuable insight into issues not measured by a test. But it also has to be appreciated that teachers are people and such an assessment is inevitably subjective and can be coloured by their relationship to the child. Teacher's can get it horribly wrong, frankly, though they can also tell you very useful stuff not picked up by a test.
At an end of year parents evening, if the data is available, you should expect to get both the teacher assessment, and both NC levels and standardised scores if the exams that have been taken are capable of generating them. If a teacher cannot give you such scores because the exams taken are not capable of generating them there is a good case for asking why the school is not using suitable exams. For a teacher to REFUSE to provide standardised scores is, in my view, an unacceptable professional inadequacy and should be taken up with the head teacher, and governors as necessary.
The presumptions and arrogance displayed by some of the teachers posting on this thread are staggering. I know how to interpret scores and NC levels thank you very much, and I am not interested in having my time wasted at parents' evenings on "whole child" drivel. I have had to listen to teachers get my child's maths ability wrong to the point of ludicrousness while wanting to waste time expressing their idiotic concerns about his not joining in maypole dancing. I suggest that the teachers posting their nonsense here realise that this is primarily a thread for parents, not for teachers to post union propaganda with no basis in good teaching practice.
