Why do pupils and parents choose St Mary’s Calne? There are, of course, many factors that are taken into account. St Mary’s is a school that prides itself on its outstanding academics, music, drama, art, sport, the Houses, the Tutor system and our commitment to the individual girl. There is also an additional factor, an X-factor: the clubs, societies, Enrichment Week activities, the DofE, the trips, the speakers and much more besides, enshrined in our values, that makes St Mary’s distinct from other schools. We have decided to give this X-factor a name – the Donaldson Programme.
