what do I do to become a substitute?

    I am moving to the Fort Knox area in about a week or so. I
    have already filled out paperwork and received a license to
    be a subsititute teacher in Kentucky. I was just wondering
    what you have to do to become enrolled in the schools to
    substitute. Is there a general phone number to call to get
    registered or do you have to enroll with each school
    separately? If anyone has any information, that would be
    great!! Thanks!!
