How can I market myself best as a choral music educator?

Hi Kylie! I am so glad that you want to pursue choral music. Yay! First, as you mentioned, you will need to get your music degree in Music Education. As for additional classes, perhaps you can start your own choir. Whether you start one now or in college is up to you. But the more experience you get, the better off your chances will be when a school is looking to hire you. Sing in a choir now and continue to throughout college. This will increase your knowledge of the repertoire. You will know what it is like to be in the choir before you stand in front of it to lead. You can observe how the director conducts rehearsals, how he/she teaches the music. You can decide what you like - if you want to teach in the same way - or decide what you think you would do differently. This is part of your education! If you find a good conductor whose style and methods you admire, then see if he/she can mentor you. Let him/her know your desire to become a choral conductor. Work hard at it. Study choral music. Listen to choral music. Immerse yourself in it. Find libraries where you can borrow choral music scores and study them. Persevere. And if need be, be willing to relocate to your dream job. I wish you all the best!
