# Letter vs anumber grades--equivalency?

## Recommended Posts

Could someone please give me a quick equivalency between letter and number grades for high school? Some parents have asked me to grade their students English essays but while I have a gut feeling for letter grades, I'm not sure what the equivalent ranges are in numerical scores (for high school--I've taught at university, but am not sure the equivalencies are the same).

Thank you.

I think most standard high school classes use:

90-100 A

89-89 B

70-79 C

60-69 D

below 60 F

However, some classes and schools skew higher such that 93-100 A; 85-92 B; etc. I've even seen some English classes where grades are given on a 5 point scale: 5-A+; 4.8-5 A; 4.5-4.7 A-; etc.

Is this what you're looking for?

Hi Cynthia,

Is that pretty standard for high school--that under 60% is a failure? I thought it was still 50% for a pass. ??

I seem to remember that at my husband's high school they don't give Ds and under 70 is failing. I'll check with him later. Anywhere I've gone to school with number grades, under 70 has been failing.

It was always under 60% for failure in my schools. Of course, that may have changed from the "olden days" of my high school years. I know that the parents in our co-op consider anything in the 60's a grade of D which translates to a lot of requests for extra credit work in my classes. So I think most parents would consider below 60% to be failing.

I do remember, though, that Singapore math had a very unique grading scale which gave anything over about a 75% a grade of an A - that was hard to wrap my mind around.

My high school used the 10-point scale that Cynthia posted. My dd's high school uses 93-100 = A, 85-92 = B, 77-84 = C, 70-76 = D, under 70 = F.

These are the two grading scales I have seen/used.

Maybe this is a Canadian/US difference? Even back in the dark ages, below 70 was an F at my Catholic school and under 60 was an F in public.

It is a state to state difference. I'm from California (90-100 is A), started homeschooling in Virginia (94-100 was A), and in SC (93-100 is A). If you do a google search on your state's grading scale, it should come up. Also, you can search for a weighted scale, since honors classes have a higher grade point.

Oops, just saw the Canada.... little slow today. Maybe it will work the same to do a search.
