News Overview
- A study commissioned by the State Bar of California found that the automated essay scoring system used for the bar exam favors shorter answers, potentially disadvantaging test takers who write more comprehensive responses.
- The study compared scores from the automated system to those from human graders and revealed a correlation between essay length and higher AI scores.
- The findings have prompted debate and raised concerns about the fairness and accuracy of using AI in high-stakes testing.

In-Depth Analysis
The article focuses on a study examining the performance of the automated essay scoring (AES) system used by the State Bar of California. The key findings are:
- Shorter Essays Favored: The AI grader, despite being designed to assess content and analysis, showed a tendency to award higher scores to shorter essays. This suggests the system may be prioritizing conciseness over depth of argument and thoroughness of legal reasoning.
- Discrepancy with Human Graders: The study highlighted a divergence between the AI’s scoring and the scores assigned by human graders. Human graders presumably weigh factors such as legal analysis, application of the law, and comprehensiveness of the response more heavily than the AI seems to.
- Score Adjustment: As a result of these findings, the State Bar of California agreed to reduce scores awarded by the AI system to account for the potential bias. This intervention indicates the Bar’s acknowledgement of the AI’s limitations and an attempt to mitigate unfairness.
- Context of Implementation: The AI grading system was implemented in response to a court order related to reducing grading biases. It was intended to improve objectivity and efficiency. However, the study suggests unintended consequences and limitations of this approach.
- Implications for Legal Education: This situation raises questions about how law schools prepare students for exams that are increasingly graded, at least in part, by algorithms. It might incentivize students to focus on brevity rather than comprehensive legal analysis.
Commentary
The findings of this study are significant. While AI offers the potential for more efficient and objective grading, its limitations in understanding the nuances of legal reasoning are evident. The fact that the AI favors shorter essays raises serious concerns about its ability to accurately assess a candidate’s legal competency. This highlights the critical importance of rigorous testing and validation of AI systems before they are deployed in high-stakes educational or professional assessments. The State Bar’s decision to adjust scores is a responsible step, but it underscores the need for ongoing monitoring and refinement of AI grading systems to ensure fairness and validity. Looking ahead, it’s crucial that law schools adapt their curricula to address the influence of AI-driven grading and emphasize the importance of both clear and comprehensive legal writing. This situation also highlights the risk of over-reliance on technology in the assessment of complex skills, as even sophisticated AI systems can still struggle with the subtleties of human judgment.
