Subtests |
Mechanical Reasoning (MRT2)
Measures the ability to understand mechanical concepts and
physical principles in operation.
The items have been selected from a wide range of areas
(including optics, electricity, fluids and mechanics), so users can be
confident that they are measuring a broad aptitude including mechanical
comprehension.
Spatial Reasoning (SRT2)
Measures spatial ability from two perspectives
- Visually constructing a three dimensional object.
- Visually relating an object to its pre-constructed patterned form.
The test consists of a number of diagrams which assess the
ability to visualise shapes and objects in three dimensions.
The items have been selected to represent a wide range of
shapes like cubes, pyramids, cones, rhomboids and an innovative variety of
other multifaceted shapes.
Therefore, users can be confident that they are measuring a
broad spatial/diagrammatic ability.
The Visual Acuity Test (VAC2)
The Visual Acuity Test was specifically designed to be
administered on computer.
It measures the ability (and disposition) to work with
highly detailed technical material such as wiring or circuit diagrams.
Respondents have to follow a single pathway through a complex maze.
The test assesses visual and attentional capacity which is
relatively independent of general ability. The VAC2 has been specifically
developed to assess apprentices in roles which involve checking, repairing and
replacing electrical/electronic circuitry and components.
