General Intelligence also known as Intelligence Quotient (IQ), General Cognitive Ability and General Mental Ability (GMA) tests, have been researched for nearly 100 years and there is substantial research behind these tests which tap into a person's intelligence level, ability to quickly assimilate new information, and ability think on one's feet and solve problems.

Research has consistently shown IQ or GMA tests are the most predictive tests for on-the-job performance, training performance and career success (Schmidt & Hunter, 2004; Schmidt, Oh & Shaffer, 2016).  This research found IQ tests were even more predictive of on the job performance than previous experience, interviews, years of education and any other selection method.

GMA (IQ) tests showed any overall predictive validity for on the jobIntelligence performance across all job levels of .65 and for training performance of .67. No other selection method comes close to the predictive power of GMA (IQ) tests. If you do not have an IQ or GMA test as part of your selection testing battery then your organisation is not using the assessment method that has greatest utility to improve the quality and performance or your new hires.

Hunter, Schmidt & Le (2006) found GMA predictive validity for on the job performance ranged from .74 for professional and managerial jobs down to .39 for unskilled jobs.

Schmidt (2011) also showed that the predictive validity of GMA (IQ) tests for on the job performance was higher than that of specific aptitude tests, even when those specific aptitudes are chosen to match important aspects of the job (such as spatial perception for mechanical jobs or numerical reasoning for financial jobs).

At Niche we recommend the following IQ (GMA) tests which we have used for over many years. For the timed Wonderlic Personnel test (click here for a list of IQ norms) have created many different business norms and have a NZ business norm for the Ravens IQ test as well :

  • Online and unsupervised.
  • Has rotating items.
  • Good measure of both fluid and crystallised intelligence.
  • Requires a basic level of literacy to answer most test items.
  • Items include general knowledge, verbal, numeric and diagrammatic problems.
  • This short version of the classic Wonderlic Personnel Test is designed to be used as a quick screening tool for job applicants, prior to further testing.
  • The testing result is only reported as whether the candidate is in or outside of a desired range for a certain role. This does restrict the information gained from the test, but it can be used as a screening tool.

Raven Standard Progressive Matrices

  • Can be administered untimed or timed - 20 minutes in length.
  • Administration needs to be supervised.
  • 60 test items.
  • Paper based version of the test.
  • Been in use and researched for over 40 years.
  • Good measure of fluid intelligence.
  • Items are all diagrammatic problems, where non-verbal reasoning skills are only being assessed.
  • This IQ test is particularly useful in assessing the ability to perceive, understand and grasp complex relationships in confusing situations.
  • This ability test provides an insight into an individuals potential for training, learning and on the job problem solving.
  • In jobs where literacy may be an issue this test will give a good idea of intellect which is not related to education level nor having a good understanding of English.
  • Niche Consulting has developed a NZ business norm for this test, in addition to the test publishers norms.
