I am trying to do the same calculation, without having to put 200-odd students individually into Raiseonline's Ready Reckoner. The method described here: education.gov.uk/schools/performance/secondary_11/KS2-4_General_VA_Guide_2011_FINAL_AMENDED.pdf - pages 15-16 - seems considerably more complicated than the method described in the link posted by tombry above. I'm a bit confused about which method to use now! Thanks John
