Early in May, my eleventh-grade daughter joined tens of thousands of other high schoolers from across the country in sitting for the American history advanced placement test. Helping her prepare, I was struck by the large number of sample questions in one popular workbook that offered misleading visions of America's history. Often the topic of confusion was the nation's religious history.

Consider the following example:

3. A place where they would have the opportunity to prosper free from government regulation.
   
   
4. A society that practiced complete separation of church and state.
   
   
5. A pluralistic society in which all would be free to practice and teach their beliefs.
