If memory serves correctly, while the application is completed online, the letters of recommendation are mailed to Sen. Toomey and uploaded as attachments to Sen. Casey's application (there is a link that you will use for each document to be uploaded and attached - you will need to have the letters scanned and emailed to you or provided to you in hard copy for you to scan and upload). The format is a traditional letter. The directions for Sen. Toomey are on his website:
All students must use our online application. Third party materials such as your official transcript and SAT/ACT scores can be attached to your online application OR mailed to our Allentown office. Your three letters of recommendation must be mailed to the Allentown office and must come directly from your school or from the source of the recommendation. Please DO NOT send any part of your application to any other offices. The deadline for submission of your application is October 4, 2013. No application will be considered if it is incomplete as of 11:59 p.m. on October 4, 2013. Late applications or applications received at other offices will not be considered.
To mail your transcript, SAT/ACT scores, certification form and letters of recommendation, please use the following address only:
U.S. Senator Pat Toomey
ATTN: Jess Kemmerer
1150 S. Cedar Crest Blvd., Suite 101
Allentown, PA 18103
Phone: (610) 434-1444

Senator Casey's application also has the directions for submission with the online application. Finally, Sen. Toomey's office sent out an email last year regarding the submission of materials, essays, etc.
with poor grammar, and errors. Take heed.
