I was an older students returning to college for my certification. It was difficult to get a job so I decided to substitute. I’ve subbed for many years at various school districts. Some I like better than others. My greatest challenge as a sub was classroom management. If you cannot get this under control serving as a substitute teacher will be very frustrating. I felt over the years I learned this quite well. I enjoy talking with the older students and discussion, and the sweetness of the little ones.
