To assess the validity of a college admissions test, a researcher will correlate the test scores with the subsequent grade-point averages of students. Which type of validity is the researcher investigating?

The researcher in question is investigating predictive validity, which is how well a test, like a college admissions test, can predict future student performance, such as grade-point averages (GPA). This is often done by examining the correlation between the test scores and the students’ subsequent performance.

Explanation:

The researcher is investigating predictive validity. Predictive validity is a type of validation that gauges how well a test predicts future performance. It checks if there's a statistical correlation between test scores and the subsequent performance of the student, in this case, the students' grade-point average (GPA) after admission. In the context of a college admissions test, predictive validity helps to determine how accurately the test can predict how a student will perform academically in college.

For instance, to assess the predictive validity of the SAT in college admissions, a research report by Kobrin et al., (2008) explored the correlation between SAT scores and first-year college GPA. Usually, a high correlation suggests that the test is a good predictor of future performance.

However, it’s important to note that the accuracy of such tests is currently a topic of discussion and debate among educators and researchers. Some studies have raised concerns about the potential bias and overemphasis of SAT or ACT scores in the college admissions process.
