How is an 11 plus score calculated?
Parents searching “11 plus score calculated” usually need two things: how raw marks become age-standardised scores, and what that means for Essex CSSE cut-offs. There is no single published pass mark — use our calculator to estimate a standardised score from English and Maths raw marks.

Most UK 11+ exams do not report a simple percentage. Instead:
- Raw marks are awarded for each paper (English, Maths, and sometimes reasoning).
- Those marks are converted to age-standardised scores so a child born later in the school year is compared fairly with older classmates.
- Schools (or the consortium) combine or rank those standardised scores and apply their own cut-offs, catchment and oversubscription rules.
That is why searching for a single “11 plus pass mark” is misleading — and why a calculator that turns raw marks into an estimated standardised score is the practical next step for Essex families.
Understanding CSSE / Essex scoring
The Consortium of Selective Schools in Essex (CSSE) administers a shared English and Maths entrance exam on Saturday 19 September 2026. Raw marks are converted to standardised scores that account for your child's age in years and months.
Because standardisation depends on the cohort each year, a fixed pass mark from a previous year may not apply to 2026 entry. Schools publish how they use scores in their admissions arrangements — including catchment and borderline offers. Practising on real CSSE past papers helps you judge whether a mock score is likely to be competitive under timed conditions.
