Is a 'Board and Care' facility the same as an RCFE?

Yes.  A 'Board and Care' facility is an RCFE.  Board and care is an out-dated term used to describe a small RCFE, located in a residential home, caring for 2 to 6 residents. An RCFE can be as small as 2 beds, and as large as 2,000:  each of them is a residential care facility for the elderly (RCFE).
