First let me dispel the misconception that the NAB Assisted Living Exam is a Nursing Home Administrators Examination. It definitely is not. The NAB RCAL exam was developed by a task group of assisted living administrators from around the country and validated by a national survey of assisted living administrators from every state in the United States. The NAB exam is not a federal regulatory exam, it is a knowledge based exam designed as a tool to measure the entry level competency of assisted living administrators as part of a state regulated licensure program.
