School reports tell you how your child compares to their classmates. This tells you how they compare to peers worldwide — with a standardised score on the same scale as GL Assessment, NWEA MAP and CAT4.
AI insight: Strong pattern recognition suggests STEM aptitude. English & Literacy is the area most likely to respond to targeted practice.
GL Assessment scale · mean 100 · SD 15
Four subjects, each scored independently against international age norms.
Reading comprehension, grammar, vocabulary, analysis and inference.
Arithmetic, algebra, geometry and data interpretation, independent of curriculum.
Analogies, classifications and verbal logic — capacity to think through language.
Pattern recognition, spatial reasoning and abstract matrices — most predictive of STEM.
Add your child's age and name. Takes under two minutes — no payment, no subscription.
Questions adjust to your child's level in real time. Four subjects, ~45 minutes total — can be paused and resumed.
A standardised score, international percentile ranking, and AI-generated insights for each subject — delivered immediately after the test.
School grades measure what was taught. This measures how your child thinks.
Each question is selected based on the previous answer. Correct → harder. Wrong → recalibrated. The result is a precise ability estimate, not a raw count of right answers.
Scoring uses Item Response Theory — the same method behind NWEA MAP and CAT4. You get a standardised score with a known confidence interval, comparable across different test sittings.
Mean 100, SD 15 — the same scale used by GL Assessment, NFER, and most UK standardised tests. A score of 115 means your child is in the top 16% internationally.
John Hattie’s meta-analysis of over 900 studies places the effect size of diagnostic assessment at 0.67 — among the highest-impact interventions in education. The same adaptive test architecture is used in assessments taken by more than 10 million students worldwide, including NWEA MAP and CAT4.
Exactly what parents receive after their child completes the assessment — standardised scores, percentile rankings, subject breakdown, and AI insights.
The assessment shows your child's current standing across four independent domains: English & Literacy, Maths & Numerical Reasoning, Verbal Reasoning, and Non-Verbal Spatial Reasoning. Each domain produces a separate standardised score and percentile against international age norms — showing exactly where they stand among peers worldwide.
No. School grades measure crystallized intelligence — learned and reproduced knowledge. Many intelligent children excel in fluid intelligence: reasoning, pattern recognition, and problem-solving that school exams rarely measure. This is why a significant proportion of high-potential children can have poor grades.
Yes, completely free. Registration is required but there is no fee, subscription, or hidden cost. Upon test completion, an instant four-domain cognitive profile report is generated.
Around 45 minutes for all four subjects. The adaptive format makes fewer but more accurate measurements than standard multiple-choice tests. The test can be saved and resumed — your child can complete it across multiple sessions.
Suitable for children aged 6–17. The system automatically calibrates for each age group; questions adapt to the child's level.
The report includes: standardised scores and percentile rankings in four domains against international age norms, your child's strongest domain, priority development area, and AI-generated insights for each subject. It gives a concrete guide for school selection, selective entry preparation, and targeted support decisions.
School tests measure knowledge in a specific curriculum. This test measures cognitive ability — how the child thinks — independent of curriculum knowledge. It allows fair comparison of children from different countries or school systems.
Yes, very common. High spatial reasoning is often undervalued by standard academic tests. According to OECD data, students in the top quartile of fluid reasoning but in the bottom half of school achievement represent 12–18% of all students — a group chronically underestimated by school systems.
Yes. A report from a standardised assessment transforms parent-teacher meetings. "97th percentile in spatial reasoning" is a much more powerful advocacy tool than "seems intelligent but scattered."
Yes. Children scoring above the 90th percentile in all four domains show strong indication for gifted programme candidacy. The test also catches inconsistencies in score patterns, which can point towards specialist assessment for conditions like dyslexia, dyscalculia, or twice-exceptionality.
Free adaptive assessment across four subjects. Standardised score, international percentile ranking, and AI-powered subject insights — delivered instantly after the test.
