The rank-ordering of test results, the use of cut-off scores, or some combination of the two is commonly used to assess the test scores and make employment-related decisions about them. There are essentially three approaches that can be taken.
Firstly the organization could simply select the top scorers. This would seem to be the most obvious approach, but is does have a major drawback, at least where ‘ordinary’ jobs are concerned. In times of high unemployment the job is likely to attract some candidates who are too ‘high-powered’ and who will probably get bored quickly and more on as soon as they can. Alternatively, if unemployment is very low then all of the candidates may have poor scores and may not be up to the job. Neither of these represents a successful outcome for the organization.
The second option is to shortlist candidates who achieve more than a minimum acceptable score. This is more flexible than the above approach as it ensures that candidates who are not up to the job are excluded whilst giving the interviewer or decision maker the option to exclude candidates they feel are too high powered.
The third option is to use a minimum acceptable score in conjunction with profiling.
This approach first excludes unsuitable candidates on the basis of minimum score and then takes into account the relative strengths of each suitable candidate in all of the areas in which they have been tested. This is then used to produce a profile map which can be compared to the ‘ideal’ profile for the job. This profile will be based on a job specification compiled by an occupational psychologist, or qualified personnel professional.
This job specification will encompass the following areas:.
