1st grade starts letter grades, but not all the teachers grade the same way. In the upper elementary grades, we grade at what level they are supposed to be in--if they're a 4th grader, they are taught/graded in the 4th grade curriculum. BUT, the lower elementary grades feel that kids should be taught/graded at what level they are at---a first grader could be getting an A in reading, even though they are reading in the Kindergarten curriculum. It is noted on their report card that they are reading in a lower curriculum, but they are still considered a 1st grader and passed on, even though they only read in the K curriculum!
Sooo, I'm the wrong person to ask about this and sorry I jumped on your post
Grading is such a touchy subject. The way it is done at our school is causing major issues when these 3rd graders move up (to 4th) and have only read in the 2nd grade curriculum. (We have the same issues in math) Again, sorry for jumping on your post, just had to get it out.
