The aptitude tests you are likely to encounter through Saville Assessment are:

  • Verbal aptitude: Tests to assess candidates’ ability to understand written information by providing a section of text, and requiring the candidate to make logical deductions based on that text.
  • Numerical aptitude: Numerical aptitude tests will assess candidates’ numerical reasoning ability, the ability to analyse and interpret numerical data i.e. statistical, graphical and financial data.
  • Diagrammatic aptitude: Diagrammatic aptitude, sometimes referred to as logical or deductive reasoning, involves analysis of processes and operators and applying those operators to diagrams. Candidates will frequently be provided with a process diagram with a key and be asked to deduce missing diagrams which fit the sequence.
  • Error checking aptitude: These tests will assess candidates’ ability to check and identify verbal, numerical and coding errors. Candidates will be provided with two sets of transposed data, with one set containing errors. These errors must be successfully identified by the candidate.
  • Spatial aptitude: Spatial aptitude is the ability to apply spatial judgement and visualise objects from multiple angles. These tests will assess candidates' ability to solve rotational and transformation problems, visualise objects and notice inconsistencies. This ability may be tested for positions requiring technical ability such as science and engineering.
  • Mechanical aptitude: This test measures mechanical reasoning ability, including understanding mechanical problems, comprehending physical principles and estimating movement of objects. This ability may be used for technical positions such as engineers, production workers and designers.
