[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]89.55 rounds to 90 so should be an A-. Does the school's policy say an A- is greater or equal to 90.0 or 90? [/quote]

According to whom?[/quote]

According to math 89.55 rounds to 90 so if the minimum for an A- is 90 (not 90.0) then the kid has an A-. That isn't teacher discretion, that is math. You can try it for yourself by putting 89.55 into excel and asking it to show the number without any decimals.

Also, if the individual test grades were not reported to the tenths place, then the average of those grades shouldn't be reported to the tenths place. For example, if you measured a bunch of people's heights in centimeters, you should not report the results in millimeters. https://www.encyclopedia.com/education/news-wires-white-papers-and-books/accuracy-and-precision[/quote]

If a class doesn't round grades, they don't round, end of story. It's not some fundamental law of math that grades are rounded. Some professors do, and some professors don't as part of their policy. Also, Canvas software may report , many silly insignificant figures or in this case the OP's college student may have decided the tenths were super important, but it is up to the professor or school policy to determine which figures actually matter.

Well if the average of 89.55 was calculated based on a bunch of tests with individual scores reported to the units place (ex an 89 or a 90) then it would be incorrect to report the average to the hundredths place. That doesn't mean a teacher can't have a policy of doing that, but it means that policy doesn't get you an accurate result from a math perspective. But if a teachers wants to say that they are combining 2 and 2 and getting 5, that is within their rights, but it's not adding. What this teacher is doing is calculating grades in a way that contradicts how one would assume they had been calculated based on the rules of math. Unless the school has a policy that the cutoff is a 90.0 and individual tests are reported to the tenths place.[/quote]
