WeBWorK review
A free, math-focused grader with individualized exercises and a large problem library.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
WeBWorK is an open-source web-based homework and assessment system for mathematics, science, and other STEM courses. It is designed for instructors who need individualized problem versions, automatic grading, immediate feedback, and performance statistics. Students can submit numeric, symbolic, string, and multiple-choice answers, while instructors can create problems and homework sets or draw from the Open Problem Library, which contains over 35,000 exercises.
Its strongest advantage is breadth within mathematics rather than broad subject coverage. Individualized versions give students different problem instances, and individualized hints and solutions support work after submission. The system also provides real-time instructor performance statistics, allowing course teams to monitor assignment results as responses arrive. This makes WeBWorK a strong fit for mathematics-heavy courses that need repeatable online assessment and a substantial reusable question bank. Courses outside mathematics and STEM may find its specialized focus less suitable.
WeBWorK supports web access and self-hosted deployment, with LTI integration for connection to learning management systems. Institutions can run their own server, while hosted options are available through external providers. The open-source model gives organizations a free software option, but implementation can involve decisions about hosting, support, and training. Choose WeBWorK when individualized math homework, automatic grading, and a large exercise library are central requirements. Consider an alternative when a broader subject focus or a fully managed delivery model is more important than mathematical assessment depth.
