Girls would slowly be enrolled in Randwick Boys' High over several years if a proposal to turn it into a co-educational school is endorsed by the community.

The Department of Education is surveying the community to canvas views on the idea, following calls from local parents for another co-ed public school option in a region crowded with single-sex private schools.

Debate has raged over the future of Randwick Boys' and Girls' High for decades, but plans to merge the two schools have always met resistance from the girls' parents. The latest proposal is to keep the girls' school, and turn the boys' school into a co-ed school.

The survey asks if respondents support the proposal, whether they would be likely to send their son or daughter to a Randwick comprehensive school, and, if the project went ahead, what ideas the department should take into consideration.
