A valid tool accurately measures what it claims to measure. For example, if a tool claims to predict work performance, there should be evidence supporting that claim. If it measures personality, it should clearly define what aspects of personality it assesses and how it does so accurately. Additionally, if a tool is intended for specific purposes like recruitment or development, it should be thoroughly tested to ensure it provides accurate results in those contexts.

A reliable tool consistently produces the same or similar results over time and across different testing situations.

The British Psychological Society (BPS) plays a crucial role in this area. The BPS has established globally accepted standards to evaluate whether a test can be recommended based on its psychometric properties. Their website lists tests that meet these standards, ensuring you use a tool proven to be fit for purpose.
