It occurs to me that schools could easily improve C and F by emphasising them in the curriculum; these have the biggest factors and should yield rich rewards. Special jester teachers could help to boost humour. Altering personalities may prove a little more difficult but surely talented teachers could help. On-site health and beauty consultants and perhaps cosmetic surgeons could improve the A scores.
Am I alone in suspecting that the Department for Education and Skills is already working on this equation for its "value-added" tables?
