Saint Mary's is an independent school in Worcester. The school has a mixed kindergarten, with the senior school being for girls only. It has in recent years been noted as "Worcester's Girls School" due to the closure of Alice Ottely School, also within Worcester.
It is set in large grounds with an amount of sporting facilities available for use. Music lessons are offered for many instruments, as well other extra-curricular activities. Drama is a very common activity, with yearly productions presented in the school's main hall. Productions such as Oliver!, The Rivals and Cinderella have been popular productions, as well as the production of "Room 10", including roles played by teachers. It has a choir that has won many awards in various disciplines including singing.
Duke of Edinburgh and Young Enterprise schemes are operated at the school, as well as students taking part in Cheltenham and Worcester Speech and Drama Festivals.
