Applied as a substitute teacher for grades Kindergarten through 12. Application at the time was given at the Chicago Board of Education. Had to have a college degree and proof. Transcripts from colleges attended and grade point average. An updated physical examination was required and proof of TB test . Your application was sent to Springfield, Ill and you had to pay $10.00 so that a background check could be taken. Once the results were completed a counselor would call you and you'd make an appointment to get your picture ID taken. Once this was done you waited to be called for an assignment.
