Every day, students around the world are denied the basic right to education because of bullying in school. Bullying particularly affects students who are perceived as not conforming to prevailing sexual and gender norms, including those who are believed to be lesbian, gay, bisexual, or transgender (LGBT).
There are many challenges involved in addressing homophobic bullying, especially in contexts where homosexuality is a sensitive issue or is illegal. However, there are entry points, such as policies and interventions that address violence and bullying in educational settings, which provide opportunities to address homophobic bullying.
The examples put forth in a UNESCO publication titled "Education Sector Respones to Homophobic Bullying" come from a wide range of global contexts demonstrating that it is possible to address homophobic bullying in and through schools everywhere. The report can be downloaded as a PDF from the following link: http://www.lgbt-education.info/doc/unesco/UNESCO_Homophobic_bullying_2012.pdf
Another rich source of information can be found at the homepage of Global Alliance for LGBT Education (GALE), who in 2012 published a guide to advocate for sexual diversity education. The guide is a 40 page brochure, which offers guidelines on how to analyse the education context in your country, and helps advocacy organisations to make informed decisions on what national strategy would be most helpful to make education more inclusive for LGBT people.
