Widely used commercial systems that provide functionality comparable to the Grader include:

• EasyGradePro
• GradeKeeper
• PowerSchool
• ClassMate Grader
• GradeLink
• LearnBoost
• PolyLearn

Each of these systems provides a wide variety of gradebook functionalities. In terms of such functionality, the goal for the Grader tool is to provide the important core features found in these tools, not the full range of features found in all of them. The Grader tool does provide modest functional improvements in three areas, when compared to most commercially available tools. These improvements are:

1. Higher level of flexibility in assignment categories, statistics information, and overall class grading metric

2. More interaction between the student and the instructor

3. Integrated environment for gradebook, messaging service, and assignment submission

The goals for the Grader relating to integration of tools are not met by any of the above commercial systems.
