How the test is marked
Each paper is marked to provide ‘raw’ scores. The raw scores for each paper are based on the number of correct answers.
The raw scores are then standardised to reflect the child’s age at the time they sit the test. This is to make sure no child is disadvantaged because they're born later in the school year.
Scores for the individual papers are weighted to create a total weighted score. The following formula is used to calculate the total weighted score for each child:
| English test standardised score | x 2 |
| + | |
| Mathematics test standardised score | x 2 |
| + | |
| Reasoning test standardised score | x 1 |
| = | |
| Total weighted score |
Every year a minimum total weighted score is set to determine the grammar pass mark.
This score is set at 25% of the children in the year group in Medway state primary and junior schools.
The minimum score for this year will not be known until the test has been sat and the scores have been calculated.
The minimum score for the last few years were:
- 2025 admissions: 482 (25% of the cohort assessed as grammar)
- 2024 admissions: 492 (23% of the cohort assessed as grammar)
- 2023 admissions: 488 (23% of the cohort assessed as grammar).
All children who attend Medway maintained schools, non-Medway schools or Medway independent schools whose score is above the minimum total weighted score will be assessed as grammar.
All children who have taken the tests and achieved scores that are below the minimum score will be deemed non-grammar.
