New Ideas for Assessing Students

My middle school students have to turn in their sketchbooks every week for a grade, so I always have a lot of data when compiling their report card grades.  However, assessing grades K through 5 has always been a bit tricky for me.  Our grades are based on effort and we use a one to three effort scale.  I found the "Art Portfolio" below on the Art of Education and I think I will begin using it at the end of every quarter to asses not only what the children learned, but also what they enjoyed the most.
