It can add a common measure
Georgetown 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
A Georgetown test result supports academic preparation but remains one part of a school-specific and program-aware review. 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
Georgetown considers highest SAT sections across administrations and expects the complete reporting route it specifies. A section-level plan is therefore more useful than repeatedly chasing a round total without diagnosing the limiting skill.
It cannot predict admission
Recent Georgetown cohorts commonly place the SAT around 1390–1530 and the ACT around 32–35; the institution does not publish a universal cutoff. 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
Georgetown requires official testing reports under its current application process. The useful final sitting must leave enough time for the route Georgetown accepts and for the applicant to confirm that the checklist is complete.
It cannot freeze the policy
For Georgetown, current first-year policy describes the verified scope. Testing policies, optional sections and reporting instructions can change; the application term must remain attached to every operational decision.
