It can add a common measure
Yale can read an SAT or ACT beside students from very different high schools. The score may clarify academic preparation when the local transcript is unfamiliar, but its meaning still depends on course access and performance.
It cannot replace curriculum
Yale asks readers to consider how testing fits the transcript and school environment, not whether one number clears an invisible line. Admissions readers can see whether the student pursued the strongest appropriate sequence; a composite does not manufacture missing preparation.
It can reveal a section imbalance
Yale superscores SAT and ACT; ACT Science and Writing are optional. A section-level plan is therefore more useful than repeatedly chasing a round total without diagnosing the limiting skill.
It cannot predict admission
Yale’s current guidance emphasizes contextual review rather than a single minimum. The cohort contains admitted students, not a mechanical rule. Students below, inside and above a range can receive different decisions because the application is broader.
It can guide timing
Yale accepts self-reported scores and requires verification from students who enroll. The useful final sitting must leave enough time for the route Yale accepts and for the applicant to confirm that the checklist is complete.
It cannot freeze the policy
For Yale, current policy announced in 2026 describes the verified scope. Testing policies, optional sections and reporting instructions can change; the application term must remain attached to every operational decision.
