An Iowa school district is changing its religious liberties policy after protests from secular groups.
    
The Spencer Public School District's policy allowed classes that taught opposing views of evolution and explored the Bible's role in history and literature.
    
The district said it created the policy to ensure students' rights to learn about religion in public schools.
    
Interfaith and secular groups, including Americans United for Separation of Church and State protested the plan, which said the policy promoted Christianity.
    
The school board said it will develop a new policy that will be pre-approved by lawyers, teachers and other groups.
