How is the Kent 11 Plus Scored? Raw Scores, Standardised Scores and Age Weighting Explained

How is the Kent Test scored? Understanding the scoring process in detail — not just the qualifying threshold but how the raw score is produced, how age weighting adjusts it, and what the standardised score represents — helps parents interpret practice test results accurately, track genuine progress, and understand what the result letter means when it arrives. This guide explains the complete scoring process from first answer marked to qualifying decision.

Step 1: The Raw Score

The Kent Test multiple-choice papers cover English, maths and reasoning (verbal, non-verbal and spatial skills). Each correct answer scores one mark. There is no negative marking — incorrect and unanswered questions score zero — so children should attempt every question they can reach in time.

Because there is no penalty for wrong answers, children should always attempt every question rather than leaving any blank. Guessing on questions where the child is genuinely unsure gives a statistical expectation of 20-25% correct (one in four or five options), which is always better than zero. A blank guarantees zero; a guess gives a genuine chance of a mark.

Step 2: The Age Standardisation Process

Once the raw score is calculated, GL Assessment applies its age standardisation formula. This formula uses large normative datasets collected from thousands of children who have previously sat GL Assessment tests across the country. These datasets establish the expected raw score for a child of any given age on any given test — effectively, how many questions a typical child of each specific age would correctly answer.

The standardisation formula converts each child's raw score into a position on the standardised scale relative to other children of their exact age. A child who scores more correctly than expected for their age receives a standardised score above 100; a child who scores less than expected receives a score below 100. The adjustment is larger for younger children in the cohort because the expected performance gap between younger and older children is greater — the formula compensates proportionally.

Step 3: The Standardised Score Scale

Each of the three Kent Test scores is placed on an age-standardised scale (typically about 69–141 per subject). A score around 100 is average for age; the grammar threshold uses both the aggregate of the three scores and a minimum in each subject. For 2024, KCC published 332 aggregate with no score below 106.

Why Practice Test Percentages Do Not Directly Translate

One of the most common sources of confusion for parents is interpreting practice paper results. A child who scores 80% on a practice paper has not necessarily achieved a Kent Test pass outcome — the relationship between percentage correct and standardised score depends on the child's age and the difficulty of the specific paper. The solution is to use practice papers that come with standardised score conversion tables specific to the child's age band. GL Assessment's official materials include these tables, and several established print 11+ publishers include their own conversion guides alongside their practice papers.

Paper structure and how scores are reported

Children sit an English and maths multiple-choice paper, a reasoning multiple-choice paper, and a writing exercise. Official results report three standardised scores — English, maths and reasoning — plus the aggregate. Check KCC's familiarisation booklet for that year's timings and instructions.

Our platform practices the underlying GL-style skills (including comprehension within English-style work, and NVR/spatial within reasoning) and shows practice accuracy % — not the official three-score report.
