Case Study
The Ministry of Education in Israel administers a national examination for all high school graduates. The exam covers a variety of subjects, including history and literature.
Two human graders are assigned to each score, often taking weeks or months to grade. To remove any bias, grades are calculated by taking the average score of the two. That process proved to be both expensive and time-consuming.
The Israeli Ministry of Education collaborated with Copyleaks; their goal was to see if they could increase efficiency and reduce costs.

Once the AI Grader has been trained, it will use this corpus of information to grade new submissions with nearly the same results as those that the human graders would give.
The AI grader is extremely accurate and comes within a 1% difference of the median score given by human graders.
Our AI grader is extremely efficient and can grade long written answers in less than 5 minutes. From the time the answers and dataset are shared with our team, the process typically takes 24-48 hours before final grades are assigned.
