日本人がEarly Decisionで応募してもNeed-BasedのFinancial AidがNeed-Blind扱いとなるかどうか？ですが微妙な点なので直接、ご自身で確認していただく必要があります。Amherstも同様です。
Early Decision (ED) is an early admission round in which students submit their application by November 1 and receive an admission decision by mid-December. ED admission is binding: students who apply through this process are committing to attend Dartmouth if admitted (barring extenuating circumstances such as unforeseen financial hardship).
Early Decision applicants are required to sign the Early Decision Agreement, which commits the applicant to enroll at Dartmouth if admitted. In other words, the agreement is binding.
Applicants may apply to other schools through non-restricted and non-binding application processes, but are prohibited from submitting binding early applications to other colleges.
If admitted early to Dartmouth and another school, the applicant will be expected to enroll at Dartmouth and decline any other offer of admission.
Dartmouth guarantees to meet 100% of the demonstrated financial needof all admitted students and provides admitted early applicants with estimated financial aid awards. In the event that an aid award is not sufficient, families are encouraged to contact the Financial Aid Office with any concerns they may have. In the unlikely event that the Financial Aid Office and the family cannot reach an agreement regarding appropriate aid, the College will release the admitted student from their commitment to enroll.
