Katenar's thread about report cads sparked an interest about grades. What kind of grading system do you use? Is it letters or numbers? We use numbers on a 4 point scale. It makes grading easier but I hate it because the parents don't understand it. Here it is: 4-advanced 3-proficient 2-partially proficient 1-far below proficiency However, out school hasn't set a standard for what proficient means Some teachers set 70% as proficient while others say 80% is proficient. For a 2 I have seen everything from 60-79%, 50-79%, 50-74%, etc.
