As a web design instructor, your job is to teach classes on the schedule you or your school sets for the program.
You create the lessons, explain how different computers can affect code, and evaluate the work submitted by your students. The rest of the responsibilities of this position vary based on the school with which you are affiliated. Independent web design schools typically ask you to take more of an administrative role, while colleges and universities treat you similar to any other professor they hire. Expect to respond to questions from students, act as a substitute teacher on occasion, and attend graduation ceremonies.
