Evidence from IGLYO’s members as well as research from various countries worldwide has shown a continued need for school systems to implement inclusive policies and activities across Europe. School bullying based on real or perceived sexual orientation, gender identity or gender expression – referred to as homophobic and transphobic bullying - constitutes a violation of the human right to education. Research commissioned by IGLYO in 2013 highlights the fact that homophobic and transphobic bullying not only impacts individuals while in formal education, but can also have longer term impacts on an individual’s career chances, both through recruitment and in the workplace. These guidelines supplement IGLYO’s other educational materials, and they should be used in combination with IGLYO’s Teacher’s guide to inclusive education, as well as IGLYO’s Minimum standards to combat homophobic and transphobic bullying. The guidelines also supplement OBESSU’s Guidelines on social inclusion in education, and provide detailed, in-depth information on creating a more inclusive educational environment for all, regardless of sexual orientation, gender identity or gender expression.
