Which document must provide an SAT or ACT score for the initial eligibility certification of a prospective student-athlete?

The correct answer is that the testing agency's official test-score report is essential for the initial eligibility certification of a prospective student-athlete. This document is critical because it provides a verified record of the student's standardized test scores directly from the testing agency (SAT or ACT). The NCAA requires this official report to ensure the integrity and authenticity of the scores being submitted, as these scores play a vital role in determining eligibility for participation in college sports.

While high school transcripts may contain information about coursework and grades essential for evaluating a student's academic performance, they do not provide verified test scores. Unofficial transcripts similarly lack the necessary verification from the testing agency, and thus cannot be relied upon for eligibility determination. Therefore, only the official test-score report from the testing agency meets the requirement for initial eligibility.
