11+ standardised scores: why a free calculator cannot convert your marks
A practice percentage cannot be turned into an 11+ standardised score: that needs the whole cohort and each child's age. You can check real Kent scores against the published rule.
Know which number you have
| Number | What it tells you |
|---|---|
| Raw mark | Marks earned on that paper |
| Practice percentage | Accuracy on that set |
| Provider score | A comparison within that provider only |
| Official score | The result that counts for admission |
The Kent rule
In 2025 Kent needed 332 in total with no subject below 108. The 2026 rule comes in October.
What a percentage tells you
Worked example Two kinds of number
A child gets 36 of 45 practice questions right. What can you calculate?
Answer: 36 ÷ 45 × 100 = 80% accuracy. Review the nine mistakes and pick a skill.
The trap: 80% is not a standardised score.
What about pass rates?
A pass rate needs a named year and the right group: test takers, applicants and offers are different.
- Keep the result with its entry year.
- Read each school's offer rules separately from the pass mark.
- Use practice to choose the next skill.
