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

Each of these systems provides a wide variety of grading functionality. 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. easy to use late and extra credit policies;

  2. more flexible histogram and pie graphs;

  3. automatic communication between other programs;

  4. student grade prediction.

The goals for the Grader Tool relating to public domain source code and sound pedagogical development are not met by any of the above commercial systems.

A detailed review of each related tool follows in these subsections:
