One reason for a lack of religious literacy among undergraduates and members of society at large is the virtual absence of religion in high school textbooks. Thirty high school textbooks approved for use in North Carolina in the fields of United States and world history, economics, home economics, and biology were reviewed. The review revealed the textbooks lacked information about religions and religious understandings. While it is understood that it is not the proper role of public education to promote or denigrate religion, textbooks that ignore the significance of religion cannot be neutral given that religion continues to make important claims about the world. A different test of textbook neutrality is proposed: a textbook or curriculum is neutral if it is fair to the major contenders for important truths. Under this test, it is clear that neither textbooks nor public school curricula are neutral, for they don't take religion seriously as an alternative. (DB)
