Are there any commercial or free products that assist professors with grading students? I've seen many K-12 solutions, but these are generally without robust curve options. I've seen a lot of professors that have created their own Excel spreadsheets, but I'd like to offer something a little more standardized.
Easy Grade Pro and Gradekeeper are time-tested K-12 tools, but lack extensive curve-based grading options, like weighting, adjustments for curve compliance (ability to bump grades up but only if you're still within the curve), midterm grades only counting if they help the student, and the ability to switch to P/NP if the student is in a program that isn't included on a curve.
Some of these may be very specific to my institution, but I'm looking for a starting point at least.
