ACER Mechanical Reasoning Test

The ACER Mechanical Reasoning Test is a 20-minute online screening tool designed to evaluate a candidate’s mechanical comprehension, three-dimensional spatial visualization, and ability to understand cause-and-effect relationships between machinery components. The assessment consists of 42 diagram-based questions that test knowledge of basic physical principles using realistic visual scenarios rather than text-heavy problems.

About this Test

Ensure that your applicants have good mechanical understanding, space visualization and recognize cause-effect relationships with the ACER Mechanical Reasoning Test.

The ACER Mechanical Reasoning Test is an on-line test that measures a candidate’s understanding of very basic principles of physics in general and mechanics in particular; the ability to visualize the movement of objects through space (three-dimensional spatial ability); and most importantly, an understanding of cause-effect relationships between mechanical components. The test uses idiosyncratic diagrams and eliminates technical vocabulary to minimize reliance on reading ability or prior mechanical knowledge.

Best suited for trades, technical, and operational roles, including safety-sensitive environments.  The ACER Mechanical Reasoning Test is ideal for the selection of apprentices, trainees, technical/trade personnel and others involved in work of a mechanical nature.

The ACER Mechanical Reasoning Test evaluates 32 questions across 12 distinct mechanism types.

  • Assess understanding of wheels, gears, shafts, and sliding rods.
  • Evaluate logic regarding levers, pulleys, weights, and springs.
  • Measure cause-effect thinking with conveyor belts, fixed pivots, and non-fixed pivots.

All items are in the form of diagrams.
