• The work addresses the specific question or problem that was posed. It is focused, detailed, and precise. Key points are emphasized. There are no irrelevant or distracting points.
• The work could be used to teach a student: either a child or another college student, whichever is most appropriate.
• The work is clear, convincing, and logical. An explanation should be convincing to a skeptic and should not require the reader to make a leap of faith.

• The work is coherent.
