Students often learn best by doing, and they may learn programming skills best by writing many programs, ranging from simple to complex. Overworked teachers can be dismayed by the prospect of grading still more programs per student as well as teaching introductory classes with ever larger enrollments. We present GradeBot, an automatic grader for computer programming lab assignments. The automatic grading approach offers substantial advantages and opportunities, but also some disadvantages and challenges. GradeBot evaluates student programs written in any of several languages, including C, C++, Java, Perl, Tcl, and MIPS assembler. Guidance for similar projects is provided through a discussion of the construction and operation of GradeBot.

Keywords: GradeBot, grading, programming, automated grading, testbed, C, C++, Java, Perl, Tcl, MIPS, SPIM, cheating
