My Lords, I should declare an interest, in that I have one child taking A-levels and one taking GCSEs this year. So far as they are concerned, I trust their teachers; I think they will be rigorous and accurate. But, generally speaking, there is a sense of uncertainty associated with the exam boards’ quality assurance process. I heard what my noble friend said about that, but the scale of the interventions by the exam boards has to be just right. Too little and they have no impact, too much and effectively the exam boards will override the judgments made by teachers and head teachers. Can my noble friend give us any more information about the scale of the quality assurance activity by exam boards?
