Scores are not age-normed, and this is not a clinical or diagnostic test.

Engineers tend to like puzzles, and they tend to be curious about the spatial side of reasoning in particular: picturing parts, rotating them and seeing how they fit.

This test includes a spatial set for exactly that reason.

Why spatial ability matters in engineering

Spatial ability is one of the most overlooked predictors of success in STEM. In 2009 Jonathan Wai, David Lubinski and Camilla Benbow analysed Project Talent, a 1960 study of around 400,000 US high school students, and found that spatial ability in adolescence predicted who went on to STEM degrees and careers, over and above maths and verbal scores.

The classic lab test of the skill is mental rotation, introduced by Roger Shepard and Jacqueline Metzler in 1971. People took longer to decide whether two 3D shapes matched the further one was rotated, as if they were turning it in their mind.

How this test works for engineers

The test has five question types with five questions each, including the spatial set, and each set gets harder as it goes. There is no maths and no engineering knowledge involved, so your degree gives you no head start beyond comfort with diagrams.

Each question has five options, several of them plausible, so working out the rule matters more than a quick glance.
The spatial questions are a fifth of the test. Your result reflects all five types.

What scores mean for engineers

Engineers as a group score above the population average, but there is no reliable modern figure for the "average engineer IQ", and the spread within the profession is wide.

Your headline number blends all five question types. Someone strong on spatial and rule questions but average on sequences can land on the same total as someone with the opposite pattern.
