When parents first see the Nonverbal Battery section of a CogAT preparation guide, the reaction is often the same: "Wait — how do I prepare for something that has no words?" It's an understandable response. The Verbal and Quantitative batteries at least look familiar — they involve words and numbers, the things schools teach. But the Nonverbal Battery looks like nothing a child has been taught in a classroom.
This is actually the point — and it's why the Nonverbal Battery is in many ways the most important one to prepare for.
What the Nonverbal Battery actually tests
The Nonverbal Battery assesses spatial and visual reasoning — the ability to perceive relationships between shapes, figures, and patterns, and to apply those relationships to novel problems. It uses no words or numbers. All the thinking is done in the language of shapes, rotations, transformations, and spatial relationships.
The three subtests within the Nonverbal Battery are:
Figure Matrices
A 2×2 or 3×3 grid of figures in which one cell is empty. The figures in the other cells follow a pattern or rule. The student must identify the rule and select the figure that correctly fills the empty cell.
For example: a square in the top-left, a triangle in the top-right, and a circle in the bottom-left. What goes in the bottom-right? The answer depends on the rule — which might be about shape type, size, rotation, shading, or some combination of these.
Paper Folding
A piece of paper is shown being folded one or more times, then a hole is punched through it. The student must identify where the holes will appear when the paper is unfolded. This tests the ability to perform mental spatial transformations — holding a mental image and manipulating it.
Figure Classification
Three figures are shown that share a common property. The student must identify which of five answer choices belongs in the same group — i.e., which one shares the same defining property as the original three.
Research note: Spatial reasoning ability is one of the strongest predictors of later achievement in STEM disciplines. A landmark meta-analysis by Uttal and colleagues (2013), published in Psychological Science, reviewed 217 studies and found that spatial skills are highly malleable — with a mean training effect size of 0.47, larger than the training gains typically seen for other cognitive skills. The review concluded that spatial training effects transfer to novel spatial tasks and persist over time, providing a strong evidence base for targeted spatial practice. See: Uttal et al., 2013 (PMC).
Why it matters beyond the test: Spatial reasoning ability is one of the strongest predictors of success in STEM fields — mathematics, physics, engineering, architecture, and computer science all draw heavily on the ability to think spatially. Developing this skill has benefits far beyond gifted programme entry.
Why children find the Nonverbal Battery hardest
The Nonverbal Battery is consistently the section of the CogAT where children who are otherwise strong performers lose the most points — not because it measures something they're less capable of, but because it measures something they've practised less.
Most children spend thousands of hours on verbal and mathematical activities between birth and school age. They hear and use language constantly. They count, sort, and do simple arithmetic. But pure spatial-visual reasoning — the kind the Nonverbal Battery tests — is rarely explicitly developed.
This means two things. First, the performance gap between children who have and haven't practised spatial reasoning is larger for the Nonverbal Battery than for the other two. Second, the room for improvement through targeted practice is also larger.
The rules that govern figure matrices
One of the most effective preparation strategies for figure matrices is teaching children to systematically check for the most common transformation rules. Matrices on the CogAT almost always follow one of these patterns:
| Rule type | What to look for |
|---|---|
| Rotation | Does the figure rotate by a consistent number of degrees across rows or columns? |
| Size change | Do figures get larger or smaller in a consistent progression? |
| Shading/fill | Does the fill pattern change in a consistent way (solid → striped → empty)? |
| Number of elements | Does the number of sides, dots, or shapes in each figure increase or decrease? |
| Addition/subtraction | Is the figure in the third column the result of combining or subtracting the first two? |
| Reflection/symmetry | Is the figure mirrored horizontally or vertically? |
| Style preservation | Does each row/column contain one of each of a set of shape types? |
Teaching children to ask "is there a rotation? is there a size change? is there a shading pattern?" systematically — rather than staring at the matrix hoping the answer jumps out — dramatically improves accuracy, particularly under the time pressure of the actual test.
Strategies for paper folding questions
Paper folding questions are uniquely challenging because they require holding a mental simulation in working memory — and working memory capacity varies substantially between children at the same age.
The most effective strategy is physical practice. If your child is struggling with paper folding questions, the single best thing you can do is practice with actual paper. Fold a piece of paper once, punch a hole (or mark a dot with a pencil), then unfold it and look at where the holes appear. Do this five or six times. Then try to predict where the holes will appear before unfolding.
Practical tips: Supervise hole punching for young children. Progress from a single fold to two folds, then three as confidence grows — each additional fold doubles the number of holes, which meaningfully increases the difficulty. A standard office stapler or a finger-press hole punch works well for family practice without requiring scissors.
This physical experience builds the mental model that the test questions tap into. After doing this with real paper ten or fifteen times, most children find the abstract version in the test significantly more manageable.
How much room for improvement is there?
Research and practitioner experience consistently suggest that the Nonverbal Battery is often the most improvable through targeted practice for many children — though individual outcomes vary. The meta-analytic evidence from Uttal et al. (2013) reports moderate average effect sizes (Hedges's g = 0.47) with meaningful transfer to related spatial tasks, but this represents an average across diverse children and training types; some children will see larger gains, others smaller. The general pattern holds for three reasons:
- The question formats are highly learnable — once you know the rules that matrices follow, you can apply a systematic approach
- Spatial reasoning responds more quickly to environmental enrichment than verbal reasoning, which develops more slowly
- Most children have had far less exposure to spatial challenges than to verbal or numerical ones — meaning the baseline is lower and the ceiling is relatively higher
A note on expectations: The Uttal et al. (2013) meta-analysis reports moderate average training effects — an improvement of roughly half a standard deviation relative to control groups, with evidence of transfer to untrained spatial tasks. Importantly, the review also found that these effects held at follow-up testing, suggesting the gains persist rather than fading immediately. However, these are population averages, and individual outcomes vary. Some children will show larger improvements, others smaller, depending on their starting level, the consistency of practice, and how the training addresses their specific weaknesses.
For children who perform significantly stronger on Verbal and Quantitative than on Nonverbal, targeted nonverbal preparation is particularly valuable. Bringing the nonverbal score up towards the level of the other two batteries can meaningfully improve the composite score — and in many cases make the difference between qualifying and not qualifying for a programme.
Everyday activities that build nonverbal reasoning
Beyond formal practice sessions, a number of everyday activities build the spatial reasoning skills the Nonverbal Battery tests:
- Jigsaw puzzles — especially for children under 8, where puzzles are consistently the strongest spatial development tool
- LEGO and block construction — particularly building from instructions, which requires translating a 2D diagram into 3D spatial reality
- Origami — probably the closest everyday activity to paper-folding test questions
- Tangram sets — geometric shape puzzles that directly build figure classification and spatial manipulation skills
- Drawing — particularly observational drawing, which trains spatial-perceptual accuracy
The nonverbal preparation priority
If you have limited preparation time, prioritise the Nonverbal Battery over the Verbal and Quantitative. Most children have had more natural exposure to verbal and numerical reasoning through schooling and family life. The Nonverbal Battery is where targeted practice has the highest return — and where the performance gap between prepared and unprepared children is largest.
