Residential halls have been seen as an essential microsystem that can promote desirable academic, personal, and social outcomes. However, the extent to which residential education maps onto universities’ educational aims remains ambiguous. Therefore, a study was conducted in two stages, using a mixed-method approach to examine the strength of the alignment between universities’ educational aims and residential educational aims among four government-funded universities in Hong Kong. The results clarify the nature of residential educational aims and found that educators should avoid projecting an ultimate set of residential educational aims onto every institution regardless of the underlying conditions and settings.
