All organizations need to measure the effectiveness of their selection tools. Some may not know what a validation study is and that it’s available to provide a significant benefit to your selection process, or some may think the only time to conduct one would be if there are legal challenges. However, there are many reasons to conduct a validation study that are not directly related to legal challenges. A criterion-related validation study examines the scores on a pre-employment assessment and how they correlate with performance on the job, such that one would expect that individuals who score higher on your assessment tool perform better on the job than individuals who scored lower on the assessment. This process can be used not only on assessments, but any part of your selection process.
