This article describes a dual grading process, initiated to expose students to collaborative evaluation and to verify instructor evaluation. Each group was assigned a case, with directions to print five copies of its response. I evaluated one copy, then distributed four blank copies to another group for evaluation. The group reviewed the paper and assigned a grade. I collected the graded responses, attached my graded copy, and returned the two graded copies to the composing group. Receiving feedback from both teacher and students reinforced the students' confidence in the evaluation process while teaching them important lessons on audience expectations.
