A second point to remember is that, even experienced instructional staff might look at the same project and arrive at dissimilar grades. The idea of the written practical grading criteria is to take out the subjectivity component and replace it with a uniform and objective system. A third area to keep in mind is that the development of set grading criteria is meaningless if it goes unused. The logic will result in a limitation for the school. The task does not have to be as cumbersome as it might initially appear.
Some schools mirror the practical assessment used by the respective state boards.
There is an advantage to this wisdom since graduates of the school will have less anxiety and have a more informed understanding of what to expect prior to taking the licensing examination. It is up to the school to develop a system to work within the structures already established. This might make the task seem less intimidating. Then have a staff meeting to discuss the grading system so that all instructors are aware of and agree upon the new assessment methods. The amount of areas to be graded within a certain project has to be determined by the school.
