What is predictive validity and its example?

Predictive validity is the degree to which test scores accurately predict scores on a criterion measure. A conspicuous example is the degree to which college admissions test scores predict college grade point average (GPA).

How is predictive validity evidence obtained?

To determine if predictive validity exists, we could use the following process:

  1. Administer the college entrance exam to 1,000 seniors.
  2. One year later, collect data on the first semester GPA of the same 1,000 students.
  3. Calculate the correlation between the scores on the entrance exam and the first semester GPA.

What is predictive validity in testing and why is it important?
