Answer:
Concurrent validation
Step-by-step explanation:
Concurrent validity is demonstrated when a test correlates well with a measure that has previously been validated. The two measures maybe for the same construct, but more often used for different, but presumably related constructs.
An Example of Concurrent Validity:
Researchers give a group of students a new test, designed to measure mathematical aptitude. They then compare this with the test scores already held by the school, a recognized and reliable judge of mathematical ability. Bjorn measuring the cognitive ability of 100 existing managers and also asks their supervisors to rate their performance is known as concurrent validation study.
