I am a substitute teacher in California with an emergency credential substituting in two districts five Middle Schools. I have been subbing in retirement for the past 5 years averaging over 120 school days per year. I have engineering and M.B.A.degrees from The University of Michigan. I have over 40 years experience in senior management positions and startup companies. My wife and I are considering a move to Colorado Springs and wanted some advice how I may become a substitute teacher in Colorado. Is it possible without a full time teacher certification as it is in California? Any comments would be appreciated. Thank you
