Writing assessment - Criterion scale

just what I needed thank you

This is a very good tool for assessing writing, and also it's very objective. Can someone clarify the following? What indicators should go for each item? 0 and 1? 1,2 or 3? The sum in the end says "9+any4" what does this mean?

Clear and easy to use resource for levelling writing- an activity most of us would admit we dread? Thanks v. much
