I forgot one important point, when you work for a public school system (any government job) or get a state license(such as in financial planning, my profession) you must go through a background check. The state takes your fingerprints and runs through the California Department of Justice. When you get a Series 6 license you must follow the same process, but through both the state and federal system. Why did this web site ,especially one that deals with educating children run a simple background check?
They didn't because they don't require teaching credentials, just a BA.
