What does the chart show?
The interactive graphic shows the combinations of the ten most popular subjects at either GCSE or A Level (as measured by total number of entries) offered by centres in England in 2014-2015. That year GCSE Full Course qualifications were offered by 5616 examination centres across 94 subjects for a total of 18.7 million candidate entries; A Level qualifications were offered by 3441 examination centres across 87 subjects for a total of 2.9 million candidate entries. However any given centre might only offer a subset of these subjects; for example, 25% of centres offered fewer than 15 subjects.
Why is the chart interesting?
Using the interactive graphic, one can explore the connections between the subjects offered by centres in GCSE and A Level qualifications. For example, one can see that:
- Nearly all centres that offered the top ten GCSE and A Level subjects also offered Mathematics. 94% of centres that offered GCSE Religious Studies and 100% of centres that offered A Level Economics offered the respective Mathematics qualification and all other subjects lie within this range.
- At GCSE, 97% of the centres that offered Biology also offered Core Science and 94% offered Additional Science. However, only 64% of the centres that offered Core Science and 71% of those that offered Additional Science also offered Biology. This suggests that many centres cater for a range of student abilities in their provision of science subjects, rather than only offering either Core and Additional Science or specific disciplines (i.e. Biology, Chemistry, Physics).
- At A Level, almost all centres that offered one science also offered other science subjects. For example, 97% of the centres that offered Physics and 98% of the centres that offered Chemistry also offered Biology. The uptake was slightly lower for Physics, which was offered by 93% of Biology centres and 95% of Chemistry centres. (A similar pattern exists for GCSE science disciplines but it is not shown in the interactive because Chemistry and Physics fall outside of the top ten subjects).
