This might be a weird question. But here we go.
I'm applying for business/data-related master programs.
I'm a stutter with a certified moderate language disorder.
Do I need to tell my professors (who provides recommendation letters) the fact of my disorder?
I'm afraid that the recommendation letter or the questions asked by the master programs require my professors to evaluate my oral English level. If they don't know this fact, they may attribute my stutter to my English (I'm an international student btw).
Added: is it common that the professors are required by master programs to evaluate the students' oral English skills in RL.
