There is a lack of lesbian, gay, bisexual and transgender (LGBT) representation on Welsh literature courses in schools, it is claimed.
Of the 48 set texts on Welsh literature for GSCE and A-levels, there is little mention of LGBTQ+ characters or themes.
One pupil donated her own books to the school library because she felt it was so important students felt represented.
The Welsh Joint Education Committee (WJEC) said new literature would be commissioned by 2025.
