3-D Reasoning Aptitude Test

The 3D Spatial Reasoning Test assesses 3-dimensional thinking in maintenance technician, mechanic, machine designer, architect, draftsman, and CAD roles.


The 3-D Reasoning Aptitude Test is designed for maintenance technician, mechanic, machine designer, architect, draftsman, and CAD technicians.  Hire people who have the skills you need for the work you intend to have them doing!  Before you invest time and money to train a new employee, test your applicants for their abilities in:

  • Machine Setup
  • Troubleshooting
  • Mechanical Conceptualization
  • Spatial Reasoning

This test provides the answers you need to make informed hiring and promotion decisions.

Purpose: The 3-D Reasoning Aptitude Test evaluates a person’s ability to think in terms of three dimensions and to see how solid objects fit together. It is appropriate for any job where the employee must be able to conceptualize how parts fit together in ways that are unable to be visualized from the surface.

When To Use It: The 3-0 Spatial Reasoning Test should be used to assess fit for jobs where the individual is responsible for taking things apart and putting things together (e.g., machine setup, mechanical troubleshooting), as well as for design work with solid objects that must fit together (e.g., architectural drawings, equipment design)

Target Group: We recommend using this test for positions such as maintenance technician, mechanic, machine designer, architect, draftsman, CAD technicians.

High Scorers: People scoring high on the 3-D Spatial Reasoning Test are better able to see how parts fit together, so they are quicker and more capable in accomplishing tasks.

Low Scorers: People scoring low on the 3-0 Spatial Reasoning Test may not be able to perform the same tasks as high scorers. They may not be able to figure out the relationships of how objects fit together, so their efforts to do troubleshooting or design work may be exceedingly long-they often need assistance from other workers to complete their assignment.
