In the United States, most jurisdictions require applicants to pass the Bar Exam in order to practice law. This exam typically requires several years of education and preparation (seven years of post-secondary education, including three years at an accredited law school).

In a publication from Dec 29, 2022, the authors evaluated the performance of GPT-3.5 on the multiple choice part of the exam. While GPT is not yet passing that part of the exam, it significantly exceeded the baseline random chance rate
of 25% and reached the average human passing rate for the categories Evidence and Torts.
On average, GPT is performing about 17% worse than human test-takers across all categories.

Similar to this publication is the report that ChatGPT was able to pass the Wharton Master of Business Applications (MBA) exam.

On March 15, 2023, a paper was published that stated that GPT-4  significantly outperforms both human test-takers and prior models, demonstrating a 26% increase over GPT-3.5 and beating humans in five of seven subject areas.
