Hi It is common (standard?) in Canadian universities for 50% to define the pass boundary (at least in the 3-4 I have taught for). It is an interesting question whether students interpret it as meaning they need to know "half" the material, but that is of course not a necessary implication of 50% (on a single test, for example) being a pass. The average mark on a test will be some function of the proportion of questions of different difficulty on the test, as implied by Steven's comment about "raising the bar." Put enough challenging questions on a test and 50% might actually represent A performance, not simply a pass. Put enough easy questions and then 60, 70, or even 80% might be a more realistic value for a pass.
It would be interesting to know how different grading standards relate to some common metric (e.g., GRE scores?). Take care Jim James M.

I'm not interested in getting into any argument about appropriateness of grading standards anywhere (since I have no idea about the details of the testing and grading procedures at your institution). That is, I realize that 50% can be quite impressive depending upon difficulty of material. But it raises an interesting question in that it conveys to students that knowing "half" the material is sufficient for a passing grade. Do others have a similar policy? Perhaps on a related note... I teach statistics at Cornell University during the summer session. I typically give exams which are a bit more challenging than the ones I have given at other institutions (because the Cornell students perform very well indeed). I'm always a bit tempted to "raise the bar" a bit given that the mean on the exams is typically in the mid-high 80% range (or higher). On the other hand, perhaps a statistics course should cover certain material and should remain relatively the same no matter where one teaches it. I have been teaching with the Gravetter & Wallnau text for almost 20 years now and find that every semester I get through less because of the ever-eroding competencies of my students. Would love to hear from others who teach at multiple institutions of differing quality. -S On May 8, 2007, at 5:14 PM, Stuart McKelvie wrote: > Dear Tipsters, > > I would not argue that the student should be given an A- in the > circumstances presented, particularly when 90% is the cutoff. > > However, the case raises interesting questions about the precision of > our grading.
