Please reassure me that I will make a good teacher, and i am not wasting my time and money. But, when it's an accomplishment for that student to learn 4 notes on recorder and make it thru the simplest song, that is teaching, and that is success. To find out, you need to get out there in teaching before you graduate. When you get enough hours, try substituting. Or, give private lessons, or do some observations.
Many states have students do observations and some hands-on when they are sophomores.
