Technical Test Battery

TTB2 measures the core skills that are required for selecting and assessing staff for engineering apprenticeships, craft apprenticeships or technical training. It consists of three tests, which can be administered individually or together, Mechanical Reasoning, Spatial Reasoning and Visual Acuity.

What TTB2 Measures

TTB2 identifies ability to understand technical concepts and put them to practical use, making it an essential assessment tool for anyone being considered for roles where technical ability is a job requirement.

Mechanical Reasoning 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, electrics, fluids and mechanics) so users can be confident that they are measuring a broad range of mechanical reasoning ability.

Spatial Reasoning measures spatial ability through items that assess the ability to visualise patterns in three dimensions and match three-dimensional objects to two-dimensional patterns. The items have been selected to represent a wide range of shapes (e.g. cubes, pyramids, cones, rhomboids and an innovative variety of other multi-faceted shapes). Therefore, users can be confident they are measuring a broad range of spatial/diagrammatic ability.

Visual Acuity has been specifically designed for on-screen assessment and measures the ability to work with highly detailed technical material such as wiring or circuit diagrams. The test involves following a single pathway through a complex maze and assesses visual and attentional capacity which is relatively independent of general ability. The Visual Acuity Test has been specifically developed for roles which involve checking, repairing and replacing electrical/electronic circuitry and components.


The TTB2 takes only 45 minutes to complete plus administration time. It can be completed in paper and pencil format as well as online and offline using the GeneSys platform. Norms exist for a variety of relevant groups.

Reports for the TTB2

Decision-maker and candidate feedback reports are provided for TTB2. Profiles in decision-maker reports present raw score, number of items attempted, sten and percentile ranks against a choice of normative samples. The group report option additionally provides decision-makers with a summary of the results from a number of respondents.
