You really need to compare to end of KS1 assessment and whether expected progress has been made. And look forward at the moment a pupil is expected to make one level's progress every 2 years, so you'd expect your DC to get 5A, 5B and 5C at the end of Y6 from these scores.
I really wouldn't get too excited about what level your DC has achieved. What is more important is attitude to school etc.
I wasn't really getting excited as such, I was looking for reassurance about maths!
She has an excellent attitude to school and is keen to work! X
