In 2017, the CPA exam added task-based simulations that require candidates to demonstrate analytical, critical thinking, and problem-solving skills. In addition, there has been an evolution in training and learning from face-to-face, synchronistic, group study, to online, asynchronistic, and independent study. These changes suggest the need to reexamine the effectiveness of CPA exam candidates' study methods. In this study, the authors analyze the degree of use and effectiveness of various study methods (e.g., instructor-led study programs, self-study review courses, flashcards, study notes, and practice problems). Based on a survey of candidates taking the CPA exam in 2018 and 2019, the authors find that the most effective method of study is practicing problems. Opposite the results of some extant research, using an instructor-led study program does not appear to increase the likelihood of passing. Because this is the only study to examine a variety of CPA exam study methods since the 2017 exam changes, its results serve as a benchmark for researchers interested in investigating future changes in study habits.
