Just one in ten teachers felt they knew enough to bring a focus on interculturalism into their lesson plan, according to a survey by the Yellow Flag School Programme.
The survey also found that only one quarter of all students felt their ethnic or cultural identity was somewhat reflected in their classroom materials.
The Yellow Flag Programme supports schoools to challenge racism and discrimination and has awarded 14 schools for their work on building inclusivity and anti-racist school environments.
A total of 14,000 teachers, pupils, parents and guardians were surveyed as part of the research being presented today.
The Yellow Flag programme supports primary and secondary schools to become more inclusive of all cultures and ethnicities, to celebrate diversity and challenge racism.
Yellow Flag coordinator Sian Abraham Long said over 55,000 students attend a school which proactively adopted the programme, but called for more Government investment to ensure schools and teachers are supported.
