c-rater Automated Scoring and Feedback Engine

c-rater™ Engine

Quickly and Efficiently Score Content

The c-rater engine provides a robust solution to scoring and feedback that uses machine learning to evaluate the content of a response, even if it contains grammatical or style errors. Backed by National Science Foundation-funded research and years of psychometric expertise, the engine provides a robust solution to scoring that looks beyond keyword matching to assess content.

The c-rater engine automatically scores responses while maintaining consistency across test takers with all the reliability of human scoring, allowing teachers to focus less on grading and more on doing what they do best — teaching and mentoring students.
