CASA

Visual-spatial abilities are used for moving, measuring, judging and navigating the physical realm. Fields with a heavy reliance on spatial ability include sports, driving, combat, maths, manual jobs, engineering, architecture, surgery and physics.

The CASA measures one aspect of intelligence. It will provide you with a 'spatial IQ score'. Other aspects are distinct and use different parts of the brain, but all areas of intelligence have some overlap.

An IQ test administered by a psychologist will cost $500-$1000. The CASA does not measure general IQ, but it is unmatched for measuring spatial ability.

The CASA test is optimized for mobile, however a larger screen provides a better viewing platform.

The CASA uses techniques for greater precision.

• - Mandatory time setting increases performance consistency.
• - Cut-off limits reduce guessing and save time.
• - Practice questions reduce performance anxiety.

You can take as much time as you like between subtests. You can log out and finish another day. Make sure you are mentally fresh and that you understand the task before starting each subtest. Our instructions contain animated visuals to help understanding.

The CASA is designed as a high-end test. It measures IQ between 70 and 170.

The CASA uses spatial tests that have 3-dimensional objects and complex visualization requirements. Most tests use spatial items with 2D models, to avoid a gender imbalance. Males outperform females on spatial tasks, and 2D models reduce this imbalance.

We provide a report after your test with your subtest scores, your overall spatial IQ (CASA score), and a standard error range.

Many spatial items are not well thought out and can be solved using simple reasoning rather than spatial ability. Here is an example from the ICAR 16 test by Cambridge University. It is not necessary to rotate the whole cube in your mind to rule out many options. The little line is pointing towards the triangular shape in cube X. It is also pointing away from the plus sign. Therefore we can rule out cubes A, B, E and G without using any spatial cognition.
