Information about the methodology for awarding grades for students is gradually being released before the official guidance comes out from exam boards. A clearer picture is emerging that the grades will be informed by your current data (see Preparing for Teacher Predictions), and it will involve an element of student ranking within your subject (ASCL, March 31st). The grades submitted will be moderated against prior KS2 data, prior school attainment data and national distributions by the exam boards. If adjustments need to be made to the distribution of grades, then the rankings will provide a fair basis on which students will move up or down a grade.
The process of ranking students brings further challenges, especially to larger departments. This more refined approach could also increase the effect of unconscious bias. So what should be taken into consideration at a subject level to ensure a fair and justifiable approach?
