Concurrent Validity
Concurrent validity is the extent to which performance on a measurement is related to current performance on a similar, previously established measurement. For example, let’s say employers have designed their own scale to assess the leadership skills of their employees. They give employees the scale to fill out on the same day as a similar, but longer and decades-old leadership test. If the scores for each employee on both tests are closely related, then the new scale is said to have high concurrent validity.
