Head Mike Walsh says the new buildings went up within an incredible five months, and are already making "an immeasurable difference". They were constructed as part of a publicprivate partnership with a local building company, sweeping away 12 old prefabs.
Sports college status has come none too soon. The school has a fine tradition of sporting achievement, with present pupils including internationals in skiing, football, volleyball and rugby league as well as the British women's under-19 table tennis champion.
But until this year St Mary's laboured with poor facilities. Now, with the award of pound;200,000 for capital investment, to be followed by a further pound;600,000 to develop staff and coaching over thenext four years, the school is a recognised centre of excellence and plans to become a top resource for other schools and the local community. Part of this involves working with nearby Frederick Holmes special school on an inclusive PE strategy.
Mike Walsh says it's all been a terrific morale booster, and provides "a tremendous opportunity for young people to develop a healthy lifestyle".
