Duke· Threshold Cliff Math
What Each Test-Score Line Is Worth at Duke
The cliff math: marginal annual aid value of crossing each ACT, SAT, and GPA threshold. Run this before deciding whether another retake is worth the prep money.
Why this page exists
Duke's automatic merit ladder has measurable cliffs between Not selected → any named scholarship and Miss Nov 15 → file Robertson application on time. The marginal dollar value of one extra ACT point isn't linear. It concentrates around the published thresholds, which is why a strategic retake is sometimes worth more than test-optional positioning. The table below is the actual marginal-value math, not generic retake advice.
The only cliff is selection itself
Because every Duke merit tier covers the same billed bundle — tuition, room, board, and mandatory fees — there are no published dollar steps between award levels to optimize across. The single threshold is whether you are selected, and the one date you control is the Robertson deadline.
| Threshold | Marginal value | What it means |
|---|---|---|
| Not selected → any named scholarship | +~$94,157/yr (full billed cost: tuition, room, board, mandatory fees, 2025-2026) | Duke has no automatic merit, so the gap from zero to a named award is the entire billed bill. This does not cover the ~$4,400-$5,100/yr of unbilled books, personal, and transportation expenses inside full cost of attendance. |
| Miss Nov 15 → file Robertson application on time | Preserves access to Robertson (tuition, room, board, most mandatory fees + 3 summers + study abroad) | The only Duke scholarship with a separate application and a hard deadline. Robertson covers most (not all) mandatory fees but adds substantial summer and study-abroad funding the other tiers do not, so it is not strictly dollar-equivalent to them. |
What Duke's merit actually pays
Duke publishes no automatic, stat-triggered merit. Every named scholarship below is competitive and covers four years of tuition, room, board, and mandatory fees (the billed bundle, ~$94,157/yr) — not the unbilled portion of full cost of attendance. Rows are ordered by how open the eligibility is.
| Profile | Outcome | Notes |
|---|---|---|
| Any admitted applicant (no separate app) | Angier B. Duke Scholarship — full tuition, room, board, mandatory fees + enrichment (~12 awards/yr) | Drawn from the admissions application; ~12 awards for the Class of 2029. Includes a no-cost Oxford summer. |
| Any admitted applicant, with demonstrated need | University Scholarship — full tuition, room, board, mandatory fees + enrichment (~10 awards/yr) | Need-and-merit hybrid: requires demonstrated financial need. |
| Separate Robertson application by Nov 15 | Robertson Scholars — full tuition, room, board, most mandatory fees + 3 summers + study abroad | The only Duke scholarship needing a separate application; joint with UNC-Chapel Hill. Covers most (not all) mandatory fees but adds substantial enrichment. Hard Nov 15 deadline. |
| North or South Carolina resident | Benjamin N. Duke Scholarship — full tuition, room, board, mandatory fees + two summer programs (~11 awards/yr) | Restricted to Carolina residents; from the admissions application. |
| International student requesting aid | Karsh International Scholarship — full tuition, room, board, mandatory fees + research funding (~9 awards/yr) | International-only; documented financial need strengthens candidacy. |
| Carolina-region resident (specific areas) | Trinity Scholarships — full tuition, room, board, mandatory fees + research/experiences (~3 awards/yr) | Restricted to specific regions of NC/SC; some awards also require demonstrated financial need. |
| Child/grandchild of a Duke alum, with need | Alumni Endowed Scholarship — full tuition, room, board, mandatory fees + summer experiences (~3 awards/yr) | Legacy + need + merit hybrid; ~3 awards for the Class of 2029. |
