Please note that there is a short video now on the SIS website to explain the new Edexcel 9-1 grading system and its equivalence with the A*-G grades with which parents will be familiar and which are still used by Cambridge Assessment International Education (formerly CIE). This may be of interest to parents whose children are doing Food, Art or Design in Years 10-11.
The 9-1 grading will also be used to describe attainment Science, Maths and English for current Year 10 students who are sitting their GCSE exams in May 2019.
The explanatory video can be found here or at the link below.
