The BFE shows up on the portal and then you are mailed a lovely certificate from your ALO. At least that's how it worked last year with my DD. Could be different in different districts.
1. Appointment certificates are being mailed directly to appointees this year due the the change in how the ALO mentor and interviewer were assigned. It is most efficient and less likely that a certificate will be lost if sent directly to the appointee. The ALO will then ask the appointee to bring the certificate to the high school award ceremony for presentation.
2. The appointment certificate is not the BFE. The BFE is still electronic as it has been for several years. Appointees must still go through their portal to accept their appointment. Once they accept, the electronic BFE will appear. Get all the BFE items done ASAP as this may delay or prevent you from inprocessing.
