Optional Recommendation Letter - Can it be sent outside of Common Application?

Hello,

I’m applying to some colleges that have an optional recommendation letter including Stanford, Wash U. St Louis, Emory, Wesleyan and Duke. I already did submit my Stanford and Emory applications.

I have my arts teacher (outside of school) and a mentor from a summer scholarship who have written additional recommendation letters and sent them to my college counselor at school.

If I submit my applications via Common App without adding an optional recommender, would my college counselor be able to email my recommendation letter(s) to these colleges? Would the admission offices accept these recommendations as part of my application?

Thank you

I would suggest Googling. The instructions are usually on the school’s website.
