The line drawing should ideally be monochromatic and completed entirely in either pencil or pen. A student may choose to use only one color, such as a red pencil or a blue pen, but this will create an effect that is less traditional. If a student uses one color, evaluate whether he used this divergence in a way that enhances the drawing overall. Since only white and one color are used, check to see that the student made use of negative (white) space.
Because shading and color are not used in this style of drawing, the actual form created by the lines is the primary focus of these drawings. If the student is attempting a realistic drawing, pay attention to the perspective and proportions. For example, for a drawing of a man beside a building, you will want to check that the man's head is in proportion to the rest of his body and that his body is in proportion to the building. If the student creates an abstract or expressive drawing, check the form for consistency in pressure and style of shapes.
Students who use shading with their pencil should be docked points, as this diverges from the style of line art. However, solid blocks of color can be used. Students who may have difficulty restraining themselves from gradation should try using a pen instead of pencil, as it is impossible to create gray or gradation with ink. Whatever the medium, evaluate the student's use of techniques, such as stippling, hatching and cross-hatching. Shadowed regions should have stippling or hatching that is closer together, appearing more dense. Evaluate how well the piece of art is enhanced by the use of these techniques.
The student's craftsmanship should be evaluated, which refers to her ability to produce a piece of art that is neat and carefully executed. Check to see that the edges of the paper are unbent, that any mistakes have been carefully erased without harming the page and that there are no stray marks or stains. This aspect is a reflection of the amount of effort and care the student has put into the piece.
