The Facts of Life (1979)

A group of girls attending a boarding school experience the joys and the trials of adolescence under the guiding hand of housemother Edna Garrett, the Drummonds' maid on Diff'rent Strokes. Later in the series, she is promoted to school dietitian, and four of the girls move into new quarters above the cafeteria. She eventually leaves the school and opens her own business, with help from the girls.
