Distances are straight lines, not travel routes. Pupil numbers and class sizes: Department of Education, 2025/26. Change is over 10 years, since 2015/16. Average class size counts mainstream classes only, and there's one class teacher for each mainstream class. Totals cover every school in the results, not just those shown.
