Differential Aptitude Tests (DAT) – Next Generation


The Differential Aptitude Tests have a history stretching back to 1947 with its original authors being amongst the most prestigious names in the history of psychometric test development. The unrivalled development history of these assessments and the accumulated validity data over more than four decades gives these publications unassailable authority.

DAT Next Gen builds on previous work carried out by The Psychological Corporation into reliable and valid measures of individual aptitudes and the results have seen the development of a shorter battery of tests with new items and UK norms.

DAT Nest Gen assesses six different types of ability, or aptitude, which can be related to success in different areas of employment. It is essentially a profiling instrument. Its co-standardised tests provide a six-point profile which portrays relative strengths and weaknesses in an individual’s key aptitudes.

The six abilities are:

  • Verbal Reasoning
    How well can you understand ideas expressed in words?
    How clearly can you think and reason with words?
  • Numerical Reasoning
    How well can you understand ideas expressed in numbers?
    How clearly can you think and reason with numbers?
  • Abstract Reasoning
    How well can you understand ideas that are not expressed in words or numbers?
    How well do you think out problems even when there are no words to guide you?
  • Mechanical Reasoning
    How easily do you grasp the common principles of physics as you see them in everyday life?
    How well do you understand the laws governing simple machinery, tools and bodies in motion?
  • Space Relations
    How well can you visualise, or form mental pictures of solid objects from looking at flat paper plans?
    How well can you think in three dimensions?
  • Language Usage
    How well can you use the English language?
    How well do you handle punctuation, capitalisation, and choice of words?

DAT Next Gen has been specifically designed for convenience and simplicity of use. Its high-quality format provides for easy administration and enables results to be interpreted quickly and with confidence.
