For future parents the school should put something in its prospectus that tells them that the school hall will be used for clubs after school for both sexes and if they find that a problem then they should choose a different school for their children.

For present parents the school should send out a letter saying that starting with the new school year in September the school hall will be used for clubs after school for both sexes and if they find that a problem then they have time to find a different school for their children.

If the school numbers go down as a result of this then the government should step in and provide the money for the school to continue for x years until the school has chance to attract parents who will understand that it is important for school halls, gyms etc. to be used after school hours and that it is important for children to be following healthy and harmless leisure activities.
