2. Education: Early Decision 2 (ED2) Trends

In college admissions, ED2 is a binding "second-chance" early application round with deadlines typically in January. AtomicmindIlumineducation

* Admission Advantage: Top universities now fill 40%–50% of their classes through early rounds (ED1 and ED2). Collegiategateway

* 2026–2027 Trends: Acceptance rates are hitting record lows (e.g., Yale at 10%, Duke at 16.5%), while schools like Yale and Brown are increasingly using "direct denials" rather than deferrals. CollegiategatewayToptieradmissions

* Strategic Shift: ED2 has become a critical tool for colleges to protect their yield, especially as application volumes increased by 12% for the Class of 2027. Collegiategateway
