Congratulations! We have received all your application information and the Admissions Committee has qualified your file. You are exactly the type of outstanding candidate the United States Military Academy is seeking.
You received a Letter of Assurance based on the overwhelming strength of your file. West Point will begin tendering most appointments at the end of February 2024 and yours will be in the first wave of packets mailed out at that time.
