In August 2019, we announced our intention to investigate the reasons for the systematic and relatively large differences in the grade boundaries set in 2018 and 2019 for the reformed A level maths specifications. Boundaries in 2019 were, in general, substantially lower than in 2018. Our work has revealed a number of interacting factors which led to the relatively large changes in grade boundaries between these 2 years. We have considered with the exam boards whether there is a case to re-visit the grade boundaries set in reformed A level maths specifications in 2018. On balance, we believe there is not.
