Hello. Can anyone please explain to me the difference between the stanine and decile score? What is more important? For example a math mock, my dc got a 118, which is a stanine of 7 (out of 9), which made me think...okay we really need to work on her math. But then I saw for the same test her decile score is 10, which then makes me think...okay, maybe her math is fine.
I know both stanine and decile compares her scores with others also doing atom, but what is the difference? Why would her stanine by 7 out of 9, but the decile 10 out of 10?
And apologies if this is a silly question, I just want to know what number I should focus on when understanding her results and what we need to work on. She is from a state school, applying for competitive London secondary schools.
