Description

The CoreN assesses an individual's ability to interpret and reason with generic numerical information. This test is suited to any role where reasoning with numerical information is a required competency. The test is not specific to any industry or role in particular therefore the CoreN can be used universally as a measure of numerical reasoning.

The test consists of 19 multiple-choice questions based on fictitious scenarios of numerical information across a range of job roles and industries.

The CoreD assesses an individual's diagrammatic reasoning ability. The candidate must use visual representations to allow them to logically solve a problem. The candidate must then find which shape or rule is missing from a diagram. This test is suited to any role where diagrammatic reasoning is a required competency. The test is not specific to any industry or role but may be especially useful in roles and industries where diagrammatic reasoning skills are essential, such as engineering, IT, management consultancy, finance and science.

The CoreS assesses an individual's spatial reasoning ability. The candidate must interpret visual information and then mentally manipulate it as required. The candidate must then understand what the shapes or images would look like as seen from a different perspective. This test is suited to any role where spatial reasoning is a required competency. The test is not specific to any industry or role but may be especially useful in roles and industries where spatial reasoning skills are essential, such as engineering, construction, manufacturing, architecture, graphic design and navigation.

The test consists of 56 multiple-choice questions containing 2D images. There are two types of spatial reasoning questions the candidates are presented with:

  • Rotational questions
  • Mirror imaging questions

The candidate must use the information presented to identify the correct answer from four possible options.
