On average, school policies had 61% of items. Chi-square comparisons found an increase in policy coverage from 2008 to 2022, notably for mentioning cyber bullying and many types of bias-based bullying; but comparisons are limited by different sampling procedures. Despite good coverage in some areas, fewer than 25% of policies mentioned responsibilities of other school staff, suggested how to help the pupil(s) doing the bullying to change their behaviour, gave advice to parents about bullying, or discussed specific powers to deal with cyberbullying and out-of school bullying.
