An Overview of Psychometric Testing: Extended DISC Questionnaire

Psychometric testing is used to improve the effectiveness of the recruitment process. It helps to accurately select the right person for the organisation.

It is critical to remember that tests should be used  in conjunction  with other sources of information on the candidate such as interviews, resume, reference checks etc.

There are two main types of tests:

  • Ability tests  assess specific individual abilities such as numerical, spelling and grammar, strategic thinking etc.
  • Personality tests  assess motivation and personality traits, such as Drive, Independence, Adaptability, etc. Understanding what motivates people and what style suits them best is critical to ensuring that employees will succeed in the job being considered.

Before selecting any particular test:

  1. Determine what you want to measure (what you are measuring must be based on the requirements of the job for which the person is being considered).
  2. Select a test that is designed to measure those abilities or personality characteristics.
  3. Make sure that you choose a test which is valid and reliable.

Tests can provide useful additional information on the candidates and  highlight areas that need to be checked during the final interview.

Tests can also be an invaluable tool to utilise  following  the recruitment process. These tools can assist in the identification of high potential employees, as well as in developing your employees.
