A university's admissions committee is debating its reliance on standardized test scores. One influential member argues, "These tests are our most objective and reliable predictor of a student's potential for success in their first year."

Based solely on this specific finding, what is your recommendation to the committee regarding the weight they should assign to these test scores, and what is your justification?
