A challenge in design education is the grading of students work when the task is based upon the student’s ability to show applied knowledge. Due to this difficulty the grading criteria needs to be and is most often subjectively focused. As previous research has shown the assessments can vary between teachers, thus, increasing the chance for varied and possibly improper scores. Much has to do with the level of experience and knowledge a particular teacher has and the individual preferences to which parameters make a good picture or animation. The Systematic Grading Procedure (SGP) is a method in which an assignment is broken down and the task is graded depending upon the assessment areas. The aim of this paper is to validate the SGP as a grading method for teachers in 3D modeling and 3D-visualisation and further develop the SGP as an assessment tool for lesser-experienced teachers. The SGP has previously shown to be helpful in giving and receiving feedback. Previous work did not show significant differences between SGP and the commonly used methods but this more extensive study did show that the SGP did significantly help reduce the variation in grading for both experienced 3D teachers and inexperienced 3D teachers but not for non-teachers. There seems to be a good potential for the SGP method to help teachers give more consistent grades and at the same time help students through feedback which helps both by helping them with a better understanding of the grading methods and measures.
