We propose a comparative judgement scheme for grading short answer questions in an online class. The scheme works by asking students to answer short answer questions. Then a multiple choice question is created whose choices are the answers given by students. We show that we can formulate a probabilistic graphical model for this scheme which lets us infer each students proficiency for answering and grading questions.
