What exactly do you mean by "technically not allowed"? What are you violating? This is common and there is nothing to get "caught" on. At the end of the day, it is the letter writer's signature. They are vouching for whatever ends up in the letter.
That isnt correct. While I personally dont think it is a great idea to do, it is perfectly legal to do so. The person who asked you to write it for them will presumably read it before signing it.
Attached is the AAMC LOR writers guide.
Awesome, I got lied to.
The reason why I made that statement was because I propose the same question as OP over 6 months ago after I got called up about one of my LOR not having all the contact information and a signature. The doctor I shadowed in a rural area in Missouri had never written a LOR before and was not aware of what is needed in the letter. So I had the bright idea of asking them if I can help him on the LOR...
Boom! The guy I was talking to switch the call over to the head of the department who gave me a huge lecture. Saying that if I help or had helped him in writing the LOR, it would be a "big problem" and would destroy my chances for med school. This is basically how the conversation went...
"The guy never written a LOR, so I just want to help him out and give him a little direction."
"No....(blah blah blah "big problem").... If he has been working as a doctor for over 10 years, he should know how to write a LOR."
"But, like I said, he lives in a very rural area and has never allowed someone to shadow him before."
"Does not matter. If he is of anyway a
respected doctor, he should know how to write a simple letter."
"..... You B@#!%" (I didn't say this part).
After that, my doctor had to figure out on his own and I felt like absolute **** because I could not help him in anyway. I hate that woman.
