The analysis presented here is from a study commissioned by UNESCO Bangkok and Plan International Thailand, and conducted by Mahidol University. There has been research on school bullying in Thailand, but only anecdotal evidence on bullying specifically targetting students who are, or are perceived to be, LGBT, or mechanisms to counter it in Thai schools. This study aimed to fill this gap in evidence, and to identify policy and programme implications. It is the first systematic study on the issue in Thailand.
