The Medway Test Pass Mark Explained: What Your Child Needs for Grammar School Entry
If you are a parent waiting for 11+ results or planning your child’s preparation, the “pass mark” is likely the most discussed—and most misunderstood—topic. Unlike a spelling test where you might need 8 out of 10 to pass, the Medway Test uses a flexible threshold that changes every single year.
Understanding how this score is calculated is essential for setting realistic goals and identifying which subjects your child should focus on during their revision.
The Top 25% Rule
The most important thing to know is that Medway Council does not set the pass mark before the exam. Instead, they set it after all the papers are marked.
The goal of the Medway Test is to identify the top 25% of the cohort (the total number of children in the year group). Once every child’s score is calculated and ranked from highest to lowest, the council draws a line at the 25th percentile. Everyone above that line is assessed as “Grammar,” and everyone below is “Non-Grammar.”
How the “Weighted Score” Works
The Medway Test consists of three papers: English, Maths, and Reasoning. However, they are not all equal. Medway uses a specific formula to calculate the final “Total Weighted Score”:
What is a “Good” Score?
Because the pass mark depends on how everyone else performs, it fluctuates. Here is a look at the minimum weighted scores required in recent years:
-
2026 Entry: 481
-
2025 Entry: 482
-
2024 Entry: 492
The maximum possible weighted score is 700. Generally, a score around 485–495 is the “safety zone,” but this depends entirely on the difficulty of the papers and the strength of the students in that specific year.
Standardisation: Fair for All Ages
You may notice that the results arrive as “Standardised Scores” rather than percentages. Standardisation is a statistical process that ensures fairness. It takes into account your child’s exact age in years and months on the day of the test.
This means a child born in August is not at a disadvantage compared to a child born the previous September. Younger children are given a small “age allowance” to compensate for being nearly a year less developed than their oldest peers.
What Happens if My Child Narrowly Misses Out?
If your child’s score is just below the threshold, there is a Review process (often called the Parental Review). This is where a panel looks at your child’s primary school work to see if they are consistently performing at a grammar school level, despite their test score. It is important to note that this happens before the formal appeal stage and is the first safety net for borderline cases.
How Tuition Academy Medway Can Help
At Tuition Academy Medway, we don’t just teach the curriculum; we teach the strategy. Because we know that English and Maths carry double the weight in the Medway Test, we ensure our students have an unshakeable foundation in these core subjects.
Our mock exams are designed to mimic the Medway weighting exactly, providing parents with a realistic “weighted score” rather than just a percentage. This helps us identify exactly where a child needs to pick up those extra few points to clear the threshold comfortably.
Success Starts with Understanding
The 11+ can feel like a numbers game, but once you understand the formula, it becomes a clear roadmap. By focusing on consistent performance across the board—and excelling in the high-weight areas—your child can approach the Medway Test with confidence.
Are you worried about where your child sits in the “top 25%”? Book an assessment with Tuition Academy Medway today to see their current projected score and get a clear plan for success.
