The Royal Grammar School Worcester (also known as RGS Worcester or RGSW) is an independent coeducational school in Worcester, England. Founded before 1291, it is one of the oldest British independent day schools. In September 2007, it merged with the neighbouring Alice Ottley School and was briefly known as RGS Worcester and the Alice Ottley School before reverting to its original name, although the School began accepting girls in 2003 prior to the merger.
