The grading of map work can be somewhat subjective and even confusing at times. There are two aspects to all map work: (1) has the information contained on the map been accurately portrayed, and (2) do the aesthetics of the map add to, or distract from, the delivery of that information? Grading the first dimension is relatively straight forward. It effectively boils down simply to the question, "is the map done". Assessing the second aspect — the aesthetics — is more difficult. Over the years I have experimented with a variety of grading methods, and one that has emerged as being the most balanced and clear, is a "√", "√-", and "√+" system.
