Primary schools
Key Stage 2 attainment includes the percentage of pupils meeting the expected standard in reading, writing and maths combined, plus average scaled scores where published.
Progress 8 and Attainment 8 do not apply to primary schools.
Secondary schools
Key Stage 4 tables cover Attainment 8, Progress 8, English and maths grade thresholds, and EBacc entry or average point score where available.
Some secondary schools also have sixth-form provision noted from GIAS; detailed 16–18 performance tables are not yet imported on this site.
Shared signals
Ofsted inspection outcomes and DfE pupil absence rates can appear for both phases when the school is in those datasets. Always check the academic year shown on the school profile.
Age ranges and key stages
Primary schools in England usually teach children from Reception to Year 6 (ages 4 to 11), with national tests at the end of Year 6. Secondary schools usually teach Year 7 to Year 11 (ages 11 to 16), with GCSEs at the end of Year 11, and many continue to sixth form to age 18.
Some areas use a different pattern, such as infant, junior, first, middle or all-through schools. A school's age range on its profile tells you which stage its data covers, so compare like with like.
Why you cannot compare primary and secondary figures
Primary and secondary measures describe different things at different ages. KS2 expected-standard percentages and Progress 8 are not on the same scale, and absence patterns differ by age. Use the measures for the phase you are choosing, and compare schools of the same phase.
