Grade Less, Teach More with Automated Feedback

CodeGrade's autograder evaluates code submissions the moment students hit submit. They get detailed, line-by-line feedback instantly. You get your evenings back.

  • Grades submissions automatically against your criteria
  • Gives students instant, actionable feedback instead of waiting days
  • Consistent and fair across every student, every time

Link tests to rubrics for clear, objective grading. Set it up once and reuse it across sections or semesters.

  • Input/output, unit, code quality, and structure tests, all drag-and-drop
  • Configure in minutes, not hours
  • Need help? Our support team, all CS graduates, will set it up with you
