I need as to how to a good LOR is written

Hello fellow Anesthesiologists,

I need letters of recommendation. 3 of my attendings (incl my ass. head of department and residency director) as well as my head of department have agreed to and would be happy to write me LORs.

I’m a final year anesthesia & ICU resident (so I’ve been in Anesthesiology for 5.5 years) in Europe. The LORs have to be US style. None of my attendings are familiar with how to write and what to include in a US-LOR (LORs aren’t really a thing here… at all). They’ve basically asked me to give them a draft and then they’ll look over/modify it.

So basically : what’s important to include, does anyone have a template, guide or an actual LOR they could give me as reference ?

Any help would be appreciated (especially templates/ real LORs that could be used as reference)

( On a side note - all of them know my work fairly well, that’s why I’ve asked them and how well/in what function they know me will be included. They would all be happy to write me a very good / great LOR so the fact that their feedback of me is actually much above average should be reflected… that sounds so arrogant 🙈 I usually don’t try to “sell” my skills in that way🙈🙈🙈)
