I average the points across the team members.  Rarely does one student's ratings greatly differ from the others.  I also have 5 rating periods so the unit that the often absent non contributing student submits his/her ratings are usually averaged out.  I've experimented this semester  with in class reporting of ratings using clickers.  It has helped in gathering the ratings.  Usually on one or two students are absent on that day.  I give them a class period to submit their ratings in writing.  In a separate self rating they discuss the team's efforts. It's amazing how the descriptions mirror and support the individual ratings.

Whether or not it's a problem depends on the specifics of how your overall grading system works. I've always used a system where each member distributes an average of 10 points to the OTHER members and, when you have a really weak member, the opposite is more of a concern (i.e. it's an advantage to the "workers"). That's because:
1) Almost with exception, the non-contributors spread their points out as evenly as the distribution rules will allow. Thus, none of the "workers" gets a score that, by itself, is likely to have a significant impact on his or her grade.
2) the non-contributor will get very few points from the "workers"--thus, they (the "workers") have more points to distribute to each other."
In general, my advice would be to tell the worried students to be honest in their evaluations and let nature take its course. If you don't think justice has been done, then you might want to take an action that corrects the problem--but still treats everyone in the class in the same way. For example, you might consider is tossing out EVERYONE's highest and lowest scores and see if that solves the problem without creating any inequities in other groups.

I hope this helps. Good luck.

A situation came up for me where a team of students wanted to know how a team member who missed a few RATs, when present rarely contributed, and almost always left at the break to miss the application exercises could fairly evaluate the team members on the peer evaluation form I distributed. They were concerned that their own evaluations would be unfairly skewed because the 'absent' student may evaluate on criteria irrelevant to the exercise. What would you do?
