Duke lets applicants opt out initially and later opt in when a score becomes useful. AP and IB results already on file remain available even when SAT or ACT is excluded.
| Choice | Duke rule | What to do | What not to assume |
|---|---|---|---|
| Apply without SAT/ACT | No disadvantage in 2026-27 | Build the academic and personal file without a missing-score apology | Optional testing means weak academics are ignored |
| Submit testing | SAT or ACT considered with the full file | Use self-reporting and verify officially after enrollment | A high score determines the decision |
| Change status | Applicants can opt in later | Use the portal before the stated review cutoff | A late result can be added after review is finished |
| ACT Science | Encouraged for STEM interests, not a universal requirement | Take it when it supports the broader list and academic story | Every Duke applicant needs Science |
A mixed-policy college list may justify SAT or ACT preparation even when Duke remains optional. The plan should preserve an early baseline, one focused improvement cycle and enough time to choose the Duke status before review.
Compare SAT and ACT section patterns, timing and repeatability before selecting a preparation path.
Read the score beside course rigor, grades, writing, recommendations and the academic interests described elsewhere.
If a later result improves the evidence, opt in by the current deadline. If not, keep the no-score choice without adding an explanation Duke does not request.
The policy allows flexibility, but superscoring, ACT Science and optional AP or IB evidence still require precise choices.
