A Great Site for Writing Assignment

I am at a conference and I learned about a great site from a professor from Cal Poly Pomona. The site, calibrated peer review, lets students grade one another papers. The unique feature of this site is that it first makes students to grade a sample work based on the rubric provided by you to see if they have the ability to grade other students work. The site is free and is provided by UCLA. We should create an account for our division.
