After doing some research online, I found a letter grade definition, written by a BC teacher. I read how the marking worked, and found that it was not very confidence building. In fact, I used to think that any C basically means fail. This was completely incorrect. The fact that C+ is 'Demonstrates good performance in relation to core-competencies' is constantly bothering me because I am sure 80% of parents don't know this fact. Usually the grade is immediately rounded to the letter. '+' and '-' are almost always ignored. Usual letter grades range from A-C then an F. Therefore, C is the second lowest possible grade. It it a real self confidence and esteem killer, the reason why I want to change this.  

Currently, the assignment marks work like this:

• A = Exceeding Expectations
• B = Fully Meets Expectations (Very Good)
• C+ = Fully Meets Expectations (Good)
• C = Minimally Meets Expectations (Ok)
• C- = Minimally Meets Expectations (Not very good)
• I = Incomplete
• F = Fail

I believe this way of marking will boost students self-esteem and self-confidence,:

• A+ = Exceeding Expectations
• A = Fully Meets Expectations (Very Good)
• A- = Fully Meets Expectations (Good)
• B = Minimally Meets Expectations (Ok)
• C = Minimally Meets Expectations (Not very good)
• I = Incomplete
• F = Fail

and even better, the more good marks a student gets, the more they will enjoy school. The chance of success will be higher if a student doesn't just give up because they got a C. This way will also increase the percentage of students getting high marks, which means more eager to learn students instead of a bunch of students that don't like school because of their grades.
