My school has changed to a competency based grading system which the mastery grade book is perfect for. However, I can't get it to work correctly. We have three levels--progressing, meeting, and exceeding with meeting=meets mastery and progressing=below mastery. Right now, My outcome looks like this:
With this system, the color coding will only code students as meets mastery or below mastery. Kids who are exceeding get lumped in with meeting. I'm assuming this is because it doesn't follow the mastery/2=below and mastery*1.5=exceeds. So, I changed the settings to look as follows:
With that setting, it marks kids as exceeds or meets, but leaves out progressing--they get lumped in with meets.
I have tried 0, 1, 2. I have tried to put it on a 75pt scale with 25, 50, 75. I have tried it on a 100pt scale with 33, 66, 100.
