How to Deal with Unfair Grading in Team Work? I was a part of a project course for about four months working as a team member in one of the teams, the project was extremely hard for all of us, but we were working real good together keeping up, but out of three of us, one was being a bit lazier than the other and usually me and one other of team members was doing most of the things, I hate to say I did everything, but as far as this is a case of rights and equality, I want to say that preparing all the presentations, writing the final reports, programming-side, all was on me.. Now when the grades have come out, the person that did the least has got the highest grade (5), while me and the other team member who did most got lower grades than them (we got 4). It wouldn't irritate me as much if all three of us had gotten 4, but it's ridiculous when the person who had put the least effort has gotten 5..

Grading was based on team members grading each other plus the instructors in charge of the course grading people too. In grading team members, I gave everybody full points, and I am very sure everyone else in my team also gave me full points, I have no doubts about that.

How would you deal with such an unfair case?
It seems to me that faculty fall into two camps on graded group work: the first is the camp that avoids it where they can, because it seems to always involve asymmetric work and annoyance, and the second uses it because they think working in groups and dealing with the inherent difficulties therein is an important skill.

Without any additional context, it seems like your professor falls into the second group.  Either that or they simply haven't reflected on the matter and are doing it because they (or the people who taught them) have always done it.  Regardless, they are unlikely to be receptive to your complaints.  Unless this is their first time doing it, you can be certain others have complained about this in the past.  In other words, part of the lesson was probably you handling the dynamics of group work, including asymmetric productivity and quality.

I should also point out that you gave this person you claim did less work a top score.  This leaves you with a very difficult case to make.

If you do decide to protest to the professor about it, I would phrase it as a question.  You want to do better, and you thought your whole group worked well together, so you want to be clear on how one person on the same project got a higher score than everyone else.  Was it based on some work they did?  Was it based just on grades from each other?  You'll get a feel quickly if the professor is interested in hearing your defense of the issue, or if you should just move on and treat it as a lesson for the future about group work.
