OKLAHOMA CITY (AP) -- The Oklahoma Senate has overwhelmingly approved a proposal to allow public schools in Oklahoma to offer an elective course on the Bible beginning next school year.

The Senate voted 38-4 Thursday in favor of the bill by Democratic state Sen. Tom Ivester of Elk City. The measure now heads to the House.

It allows the course to be taught to students in grades nine through 12.

The bill says the curriculum and course materials for the course will come from the National Council on Bible Curriculum on Public Schools.

Sen. Tom Adelson opposed the bill and says he's concerned that language requiring the course materials and curriculum to be vetted by the state Attorney General was removed from it.
