Illinois state law requires that nursing home staffing must be based on the needs of the residents. At a minimum, there must be one licensed nurse in charge during each shift who is not the Director of Nursing or Assistant Director of Nursing. The nursing home must ensure that direct care staff are available for 2.5 hours per resident each day, with 40% of those hours occurring during the day shift, 25% during the evening shift, and 15% during the night shift.
