A rubric is a scoring guide that consists of specific pre-established performance criteria, used for evaluating students' work. iRubric is a comprehensive digital rubric development, assessment, and sharing tool that shows the major skills and sub-skills to be mastered, the different mastery levels, and marks allocated to each level. This article shows how digital rubrics can be created for grammar courses using the iRubric building tool of RCampus, an Online Learning Management System, and how they can be shared through the online learning community rubric gallery.
