Wildrose Leader Danielle Smith now says she is looking at supporting the bill, which will be introduced by the Liberals in the coming weeks.
The bill would require school boards to support students who want to establish gay-straight alliances in schools.
The alliances are basically peer support networks to help prevent gay students from being intimidated or bullied.
A motion to support the alliances was rejected in the spring by a coalition of Wildrose and Progressive Conservative members, who said they didn't want to tie the hands of school officials.
The NDP supported the motion in the spring and plans to support the Liberal bill this fall.
Premier Jim Prentice says he wants to see the contents of the bill first before he comments further.Suggest a correction
