Get in the practice of jotting down the names of everyone who was in the room as soon as you walk out of your audition so you don’t forget anyone. If you don’t remember exact names but they’ve told you they are the dance instructor or the voice instructor or whatever, write those notes down as well. Then as soon as possible, go online, look up that school’s faculty bios and see if you can match photos to the person in the room. Going to a school’s website/faculty bios is also a great place to check spellings of names for anyone writing a thank you note! If all else fails and you don’t remember who was in the room, try some of the student groups that are on Facebook (or if you are working with a coach, check with the students in your coaching group). Often times you will find someone who auditioned at the same time who may be ale to help you remember who was in the room so you can thank them all properly. If worse comes to worse and you don’t have names, still send a general thank you to the department. Do not ever not send a thank you.
