We have previously published an analysis of the year-on-year variation in the percentage of students achieving A* to C in a number of GCSE subjects. We know that individual schools and colleges will always see variation in the proportion of students achieving particular grades from one year to the next. This can be due to many different factors, including differences in the ability mix of the students, different teaching approaches, changes in teaching staff or teaching time, and changes to qualifications.

Now that GCSE results for summer 2016 have been published, we have looked at the year-on-year variation in the same subjects in summer 2016. They are presented here, as well as the graphs we have previously published. This year we have also looked at the year-on-year variation in English and English language across GCSE and level 1/ level 2 certificates as there has been a large migration of students from GCSE to these GCSE alternatives in this subject in recent years. For completeness we have also included graphs showing the year-on-year variation in mathematics across GCSE and level 1/ level 2 certificates although the majority of students enter a GCSE qualification in this subject.
