225 ILCS 70/10
It shall be unlawful for any person to operate or manage a nursing home in the State of Illinois unless he or she is licensed as a nursing home administrator in accordance with this Act.
The practice of nursing home administration, or the use of the title "Licensed Nursing Home Administrator", the initials "N.H.A." or any other word or abbreviation indicating that he or she is a nursing home administrator, by any person who has not been issued a license or whose license has been suspended or revoked is hereby declared to be inimical to public health and welfare and to constitute a public nuisance.
Nothing in this Act or in the rules adopted hereunder shall require an administrator of any facility or institution operated solely by and for persons who rely exclusively upon treatment by spiritual means through prayer alone, in accordance with the creed or tenets of any well-recognized church or religious denomination, to be licensed as a nursing home administrator.
