What the data says
The Department for Education has not published where Katherine Warington School’s Year 11 leavers went next (the cohort is too small to report), so this page relies on the school’s results and subjects.

Religious Studies is unusually popular at GCSE: 94% of the year group took it, against 31% of pupils across England.
