Even though it may be true that number grades could possibly hurt a students self esteem in reality keeping number grades is necessary to help students get ahead in life with a better attitude. The grades students get in high school go beyond just that school since most students rely on their grades to get into a good college. Changing the grades so it only shows "pass" or "fail" is not a good idea because you can no longer distinguish a student who gets all A's and a student who is barley passes because for both of these students it was just say "pass". Students will probably start to slack off more because all the have to do now is pass because you won't be able to figure out by how much they are passing.
