I am a middle school band director and currently teach 140 member 7th grade band, a 90 member 8th grade band, and about 120 6th graders in small-group, weekly lessons. I am looking for some guidance on what an “ideal” teacher/student ratio should look like for that many students in a middle school band program. My 7th and 8th graders do not receive any kind of lessons. I need some hard data to bring to administrators to advocate for more teacher time. Any ideas for resources, or numbers from your own schools would be helpful. Thanks!
