Educators often use the term "rubric." According to Wikipedia, a rubric is, "a set of criteria for grading assignments."
In Acts 17:11 we read: "Now the Bereans were of more noble character than the Thessalonians, for they received the message with great eagerness and examined the Scriptures every day to see if what Paul said was true." They used the Bible as their rubric. The Bible is also our rubric.
