Should a 10-Point Grading Scale Be The Standard?

[Ares]

I don't see a big difference in this. The school I work at does not want us to give a grade lower than 50 if the student submitted the work. I only give a zero if nothing was turned in. The students that I have that are failing receive the grade that they deserve. I do not think a student should pass if they do not understand the concepts that were taught in class.

The difference is easily translating number grades to letter grades in a more uniform way that is easier to understand. It also changes the numerical threshold for where someone is failing a class. I am not a fan or arbitrary grading on useless metrics like class participation. On a 100 question test, how many questions should they have to answer correctly to pass?
