NAHT advice has been for schools to ensure that students and parents/carers are aware of the criteria for awarding A*. This was re-emphasised at a recent Ofqual consultation event. In summary, to be awarded an A* a candidate must obtain an A across all units (including AS) and average 90% in the A2 units (NB not 90% in all units) This can give rise to a situation where a candidate with a higher UMS total can be awarded an A grade than an A* candidate with a lower UMS total.
Members are advised to refer any complaints re this that occur during or in the wake of the results process to the relevant awarding body.
