Part Three: Psychometric Testing – Sample Return on Investment (ROI) Case Study

Posted on 20 Mar

Part Two of our Return on Investment (ROI) of psychometric testing series provided you with a formula you can use to work out whether the use of psychometric testing would be beneficial for your organisation.

Part Three provides a practical work up of calculating the ROI of psychometric testing. In this example, the organisation is evaluating the success of their recruitment process with and without the use of one psychometric test (in this case the ISAT).

Some background provided below.


Sample case study: Minions Electrical

Minions is a large electrical company currently employing 3500 employees, their staff turnover rate is estimated at 5% per annum. At present, it is estimated that turnover is costing Minions approximately $1240 per candidate.[1] In 2015, Minions reported 55 accidents which were estimated to cost $900 000. These costs were attributed to replacement staff, production and productivity losses, personal injury claim compensation, repair bills and travel expenses. It is acknowledged most of these accidents were a result of an interplay of various factors including poor safety procedures, however human factors were involved in 80-90% of the accidents. Minions has estimated approximately 15% of these accidents result in at least one employee’s long-term absenteeism, requiring new staff to be recruited and retrained. This cost is in addition to Minions recruitment of their standard staff turnover. Minions does not currently use psychometric testing to assess safety attitudes and behaviours.

The following scenarios outline two alternate recruitment processes and demonstrate how psychometric testing can affect overall cost savings. Scenario 1 is a standard recruitment approach of resume screening, interviews and reference checking. Scenario 2 utilises the Individual Safety Attributes Test (ISAT) in addition to this standard approach.




As shown in the comparison above, by utilising the ISAT to screen candidate’s safety attitudes as a basis for selection, Minions could save $336 720 by decreasing accidents resulting from poorly selected candidates.
