SHADING SHAPES & FORMS
	Master 5 pts	Expert 4 pts	Apprentice 3 pts	Novice 2 pts
FULL VALUE RANGE	Master Extremely effective in demonstrating ability to blend with the pencil tip to create a full range of light, medium and dark values.	Expert Effective in showing a value range that contains light, medium, and dark values. Shading may appear striped and/or un-blended.	Apprentice A partial value range was demonstrated. Blending was minimal, if present at all.	Novice Limited effort was attempted to blend and/or to show a variety of values.
LIGHT SOURCE & REFLECTED LIGHT	Master Light source is dramatic and obvious. The lightest values are closest to the light source. Edges of surface closest to light source have been lightly erased to show implied lines. Reflected light is shown in darkest values on the opposite the light source.	Expert Light source is evident. Darkest values are located opposite the light source. Reflected light has been added.	Apprentice An attempt has been made to create a light source. It may not be lined up with the lightest values of the object. Reflected light may have been added, though not in the correct spot.	Novice Limited effort was attempted to use a light source or reflected light.
NEAT & COMPLETE	Master Work is extremely neat and complete. Edges of the forms are sharp and clean. Values blend smoothy. Only whites in the form are the extremely light values.	Expert Work is fairly clean and neat. Most smudges and extra lines have been erased. Edges are somewhat clean and sharp. Some white paper is visible in the darker values.	Apprentice Weak effort given to erasing smudges and cleaning edges. Sharpness of edges is not consistent in work. White areas may be in areas other than the light values.	Novice limited effort, if any effort, is given to erasing smudges and making edges sharp. White paper showing throughout.
