Hi I am currently a high school substitute teacher and enjoy it. I was studying for the CBEST and hoping to enter the teacher credential program at age 56. I was hired as a sub with no interview which I am not good at interviews. I was told that it is quite the same after you are in the credentials program that you get hired. But I am not really sure about that. I do not want to waste my time and money going through a credential program just to go to an interview and then hear "We found someone else". Since they are not allowed to say "You are too old" I think I just found out I was fooling myself.
