can any helpfull teacher types explain why the difference between Sats scores and APP scores?

[sausagesandwich34]

they look the same 4a/5c etc but APP seem to be lower

I understand that it's a different scoring system but which is the more accurate and is it usual to be different levels

TIA

APP is day to day teacher assessment.

SAT score is the level from a one off test - a narrower snapshot. It is possible to fluke a higher level, but not have the kind of secure understanding that APP would show.

thanks

Also you can get, e.g. a level 5 on a ks2 maths paper by answering accurately all the level 3 and 4 questions. This will give you a high enough score to get level 5. APP you have to actually do the level 5 stuff consistently for it to be achieved.

What would the normal difference be - one sub-level or more?

For which subject?

Writing tends to come out lower on App, whereas higher on other schemes like the Surrey assessments.

Maths- depends on which part of APP you use. If you focus purely on number, yet a child is very strong at shape and data handling, then their result will be pulled down.

What if a dc was really consistently scoring a particular level in numeracy tests, would the teacher assessment still maybe be lower by more than one sublevel?

That's unlikely, and I would question the APP - the key word there was consistently.

It is possible to fluke a higher level, but not have the kind of secure understanding that APP would show.

This is what I don't understand and I hear a lot. One of mine typically scores two sub levels higher than level assigned in maths tests given. Often scores higher than those in higher maths sets in identical tests.

I hear that the high test scores must be a fluke. I don't know about you but if you set me a maths test with problem sums in it, percentages etc and I managed to work them out correctly it wouldn't point to a fluke.

In many private schools children sit the same maths test at the end of terms and they use the result to inform the placement in maths sets the following term. A high test result generally merits a move upward through the sets & a low one the opposite.

I refer you to my earlier answer, NorhamGardens - if a child achieved more in tests consistently, then the APP needs to be looked at more carefully. Consistently high test results are not, I agree, a fluke.
