An assessment tool is valid if it measures specific characteristics required to do a job and if the measurements are accurate. Validity is the fifth of 13 Department of Labor guidelines used for assessment instruments, and the one we will be examining this month.
We determine an assessment tool’s validity by looking at its purpose. Once we determine the tool is valid for a specific purpose, that validity cannot be transferred for any other purpose. For example, we can agree a valid instrument can predict a person’s ability to accurately measure, add and subtract. We cannot, however, use the same instrument to predict the person’s leadership or sales skills.
The validity coefficient is a strong indicator of how valid the assessment is for a specific purpose under
specific circumstances. It measures the degree of relationship between test performance and job performance.
Validity is an important characteristic in assessment tools because it gives meaning to a person’s scores on an assessment. If the evidence shows the assessment tool is a valid predictor of performance on a specific job, we know that people who earn high scores on the assessment are more likely to do the job well than people with low scores.
We can also establish an assessment’s validity as applied to specific groups. A tool that is valid in predicting how well an executive solves problems does not allow for useful comparisons about ability in clerical assistants. Additionally, the reading level of the test may not be valid for both groups.
Developers of assessments must describe the groups they used to develop the test, detail which groups can be validly tested by the assessment, and provide an interpretation of scores for individuals belonging to specific groups.
All Profiles assessments meet or exceed Department of Labor guidelines, and at HumanPoint we work diligently to help our clients understand our tools and how to use them correctly. We partner with your HR leaders to implement assessments and provide comprehensive training and support.
