It would be kinda hard for a substitiute to teach my class. I teach Autocad, and another program called Revit. For those of you who don't know these two programs. Both programs are use the engineering field. There are only four teachers in my district who can teach these classes, I am one of those 4. The last program Revit, I'm the only one who can teach this class. Subs could not do my job. I have a tech. degree from Fresno State, Industrial Tech.-Construction. Most substitiutes could not replace any high school classroom teacher. We have a teacher with a doctorate in Physic. Several with Masters in their field. I teach in a public high school, we get about 6000-7000 dollars per student. Mr. Olson only focus on the bad schools.
