推薦信 Waiver Right?

[chateau]

每間學校都會問你要不要waiver your right to examine the letter of recommendation.
是一定要放棄嗎？
我看Wharton 裡有寫
Under the Family Educational Rights and Privacy Act of 1974, students have access to their education record, including letters of recommendation. However, students may waive their right to see letters of evaluation, in which case the letters will be held in confidence.

放棄不放棄會影響你的學校申請媽？
