The North Carolina chapter of the NAACP plans what it calls a major announcement in its fight against new policies in the state's largest school district.
The civil rights organization plans to unveil a legal strategy for challenging the policies at a Saturday morning news conference in Raleigh.
The NAACP, along with other groups, has opposed the end of an effort in Wake County schools to achieve student diversity by busing.
A majority of school board members elected last year scrapped the policy, saying it prevents students from attending schools near their homes.
They say there are better ways to achieve diversity for the nearly 140,000 students in Wake County schools.
The NAACP says the changes amount to resegregating the school system.
