In 1948 the first Sister-in-Charge, Sister Lois, heralded the beginning of a 32-year period of St Aidan's having Sisters-in-Charge. For the previous 19 years the Sisters had always come out from the Community House to teach Divinity and to prepare students for confirmation. Overall the sisters' views of education were farsighted and progressive and they deplored any view which denigrated the value of education for girls. In Sister Lois' 1951 report, she stated "Girls must be equally educated as, at the very least, they will need trained, well-informed and keen minds to be capable mothers."
