Every year I try to make the Personal Project experience easier for my students and my supervisors. This year one of the things I have worked on, is a new grading document.
To save my supervisors time, they just have to highlight in green the levels the student had met. Then I can take the comments directly from these boxes. If there are any particular issues, they can add this to a general comment box too.
Here's the document. To make your own copy, select 'File' then 'Make a Copy'.
Let me know if you use it/like it/have suggestions for improving it!
