Surprise, surprise! The state of Kansas does not require background checks for all public school employees. Teachers must be vetted, but bus drivers, secretaries, para-professionals and cafeteria workers are welcome to add a criminal record, complete with a listing in the sex offender registry, to their resumes. Commission of a crime by a teacher while employed by a school is not a problem for many "unified" school districts in Kansas, either. As long as parents can be intimidated by school administration and the local "unified" school board to keep quiet about any criminal activity or behavior by teachers, it can go undetected.
