OFSTED inspectors will look at bullying and the school’s actions to prevent it and will bear in mind the importance of careful documentation and analysis such as logs and reporting methods. They will also want to hear the views of pupils and parents about the culture and ethos of the school environment and how safe pupils feel.
Here is a link to the OFSTED Inspection Handbook which schools and inspectors use when undertaking an inspection.
Discriminatory bullying - there are specific references to the need to tackle all forms of bullying including racist and homophobic bullying within the handbook. OFSTED has also produced guidance for inspectors on how they can explore if a school is doing enough to prevent homophobia - see OFSTED Guidance on preventing homophobic bullying Jan 2014 and also the specific pages relating to how to support CYP who are experiencing discriminatory bullying
