Data analysis is applied mathematics: statistical inference, probability, time series and the linear algebra behind machine learning. That is why analytics roles in finance, healthcare and marketing recruit mathematicians and why the interviews test the maths rather than the software. Students aiming at data work should keep statistics and probability strong, and learn to program alongside.

What can this guide not tell you about your own school?

The national curriculum binds maintained schools, but academies and private schools do not have to follow it — so what your child is actually taught, and when, can differ from what is described here. Your school’s own curriculum plan is the authority for your child.

The national picture, measured at the end of primary school:

“In 2025, 62% of pupils met the expected standard in all of reading, writing and maths, up from 61% in 2024.” — DfE, Key stage 2 attainment
