Grid and Value
	Accomplished 4 (N/A)	Skilled 3 (N/A)	Emerging 2 (N/A)	Limited 1 (N/A)
Grid (base and portrait)	Accomplished 4 Student will be able to apply the concepts of grid (accuracy, connected measurements, correct rows and columns, etc.) to create the base for their drawing	Skilled 3 Student will be able to construct a grid that brings the key concepts to their fullest: accuracy, correctly labeled rows and columns) for the base of their drawing	Emerging 2 Student will be able to graph a correctly proportioned grid for the base of their drawing	Limited 1 Student will be able to draw an accurate grid for the base of their portrait, however, some measurements may be slightly off. Revision or the use of multiple layout lines may improve the grid.
value scales	Accomplished 4 Students will be able to create a 5 scale Value scale for #2, 2H, 6B and HB to show true black through white	Skilled 3 Student will be able to construct a 5 scale value scale for each of the following: #2, 2H, 6B and HB to show black to white. May have a few spots of white coming through black sections, but overall black is seen	Emerging 2 Student will be able to classify and show a 5 scale value scale for each of the pencils for black to white. May need more work on some scales to show steps to next value but overall changes seen	Limited 1 Student will be able to draw 5 scale value scales for each of the pencils indicated but may be missing 1. Student may need to work more to show steps of change for each scale but base concept understood
Line weight and shapes	Accomplished 4 Student will be able to apply the concepts of varied line weight and shapes to create a contour drawing as the basis of their portrait	Skilled 3 Student will be able to differentiate lines and shapes to create the base-level drawing for the portrait. May need to lighted under-drawing	Emerging 2 Student will be able to separate various lines by weight to determine which is best per square. Varying pencils may help with the application in the future	Limited 1 Student will be able to use different line weights and shapes to determine value placement. Under drawing is too dark and could benefit from lighter pencil for future
value	Accomplished 4 Student will be able to apply concepts of value to their portrait by utilizing all pencils to maximize depth and realism in the final drawing	Skilled 3 Student will be able to use concepts of value and apply them accurately to their drawing to show depth	Emerging 2 Student will be able to modify their drawing to apply value to their work. Some areas are still overly gray but depth is starting to be seen	Limited 1 Student will be able to measure their value application by physically setting and copying the scales to their work. More differentiation is needed but the beginnings of depth is seen
Craftsmanship	Accomplished 4 Student will be able to critique their work and reappraise it to show a pristine finished piece: no under drawings are visible, grid lines are erased and no traces seen, no smudge line are visible, etc.	Skilled 3 Student will be able to assess their work and correct any areas of blemish, however, their may be a grid line or 2 seen or a few smudges seen. Overall these do not interfere with the drawing	Emerging 2 Student will be able to make observations of their work and deem where corrections should be made for future: erase better, draw lighter, blend, etc. Improvements can be made for final viewing	Limited 1 Student will be able to recognize areas of improvement and make those changes for future work. Large areas need closer clean up to raise overall grade
