An example of predictive validity is assessing the effectiveness of universities using student high school grade point averages as a key enrollment acceptance factor. Researchers compare the first year grades of students with their high school GPAs to see if their GPAs have remained close to the same.
Predictive validity is a valuable component in testing processes, particularly for psychological testing used in clinical treatment and in research. It is also essential in career and aptitude tests, as these tests help to determine how successful someone might be in a chosen occupation.
Predictive validity is a sub-category of criterion validity, which is seen as an integral aspect of education and behavioral science, as well as psychology.
