Shape Assembly Test
Game-based assessment · 3D mental rotation
Discover who can picture how 3D parts fit together
Candidates see a set of loose 3D parts and choose which of four shapes can be built from all of them, turning parts to fit. Delivered on iTestHub with Assessor and Candidate Reports.

What the Shape Assembly Test measures
Shape Assembly is a game-based test of spatial visualisation and mental rotation. Candidates see a set of loose 3D parts and choose which of four shapes can be built from all of them. Parts can be turned to fit, but mirror images do not count.
Mental rotation
Turning shapes in the mind to see how they fit.
Spatial visualisation
Picturing how separate parts combine into a whole.
Careful checking
Ruling out shapes that use the wrong parts or a mirror image.
Why organisations choose game-based assessment
Engaging for candidates
Short, interactive tasks that candidates enjoy, which helps your employer brand and completion rates.
Quick to complete
Each game takes 7 to 10 minutes, making it easy to use early in high-volume recruitment.
Measures real ability
Games measure the same abilities as traditional tests, through tasks rather than questions.
Familiar reporting
An Assessor Report and a Candidate Report, just as with our other tests.
Reports
Results are reported in the same way as our other tests: an Assessor Report showing the candidate's score band (Very Low to Very High) with interview questions, and a Candidate Report with no scores, giving supportive development advice.
Who it’s for
Shape Assembly is designed for entry-level to graduate roles that need good spatial ability.
Engineering and technical
Assess mental rotation and spatial visualisation for technical roles.
Manufacturing and production
Find candidates who check carefully how parts fit together.
Design and construction
Compare applicants on spatial ability in an engaging game format.

Count the parts
Check each option uses every part, and no more.
Watch for mirror images
A shape that only works if a part is flipped is not the answer.
Turn one part at a time
Match the most distinctive part first, then fit the rest around it.
Use the practice items
They show exactly how the parts and options work.
