Grading Explanations

Well, I have put together my first document for the new school year.  Here is my explanation to students and parents as to how grading will go in my classroom.  Please, please, please comment - I want to make sure I have this as clear as possible before I print it.

Background on my district - mostly blue collar, not a heavy emphasis on education.  Parents are somewhat involved - the parents of the "better" kids tend to be the most involved, otherwise they don't tend to get involved unless their child is failing (and even then, they don't always get involved).  I thought about including information from books/prominent educators but I chose not to because I didn't want to be perceived as trying to go over the parents heads and/or too much "edu-speak."  I wanted it to be in as plain English as possible.

So - here it is.  Comment away!  Thanks in advance for your help!

***I have revised this slightly based on the comments and changing my 0 and 1 values. (8/3)
