Lesson 1.2: Current Format, Sessions, and the January 2027 One-Day Transition

In this lesson, we will explore the current structure of the COMLEX-USA Level 3 exam, examining its format, the organization of sessions and breaks, and the upcoming transition to a one-day exam format in January 2027. This overview serves as a crucial guide for candidates preparing for this pivotal assessment, which acts as a gateway to unsupervised osteopathic practice.

Learning Objectives

By the end of this lesson, students will be able to:

Describe the 2025-2026 two-day, four-session structure with timed blocks and authorized breaks.
Identify the confirmed January 2027 move to a one-day, approximately eight-hour exam with a stated similar MCQ-to-CDM proportion.
Discuss the day-by-day, session-by-session structure and how MCQ and CDM components are distributed.
Explain what is changing in January 2027 and what remains the same, including the unchanged blueprint content distribution.
Understand the main ideas and terminology related to the Current Format and the January 2027 transition.

Introduction to the COMLEX-USA Level 3 Exam

The COMLEX-USA Level 3 exam is essential for osteopathic physicians, measuring their ability to apply medical knowledge and skills in a clinical context. As osteopathic practice progresses toward more autonomous roles, the exam serves to ensure that candidates demonstrate adequate proficiency to make informed, safe and effective clinical decisions without supervision. The structure of the exam plays a crucial role in this assessment.

Current Exam Structure (2025-2026)

Overview of the Two-Day Format

From 2025 to 2026, the COMLEX-USA Level 3 exam is structured over two days, consisting of four sessions:

Day 1:

Session 1
Session 2

Day 2:

Session 3
Session 4

Each of these sessions is carefully crafted to evaluate different competencies necessary for independent practice.

Session Timing and Breaks

Each session typically lasts about 3 to 4 hours and is embedded with authorized breaks. The break times are designed to allow candidates to recuperate and refocus between testing blocks. For example, after completing a session, candidates may have a 30-minute break before the next segment begins. It's essential for students to manage time wisely during these breaks to stay energized and alert throughout the entire examination period.

Number and Type of Questions

The current format consists of approximately 420 single-best-answer multiple-choice questions (MCQs) and around 26 clinical decision-making (CDM) cases, directly reflecting the competencies required for osteopathic practice.

Breakdown of Components

In summary, the current structure can be outlined as follows:

Number of MCQs: 420
Number of CDM Cases: 26
Total Examination Days: 2
Total Sessions: 4

Example: Session Distribution

Let's consider an example of how a particular day might look:

Day 1:
Session 1: 90 MCQs
Break: 30 minutes
Session 2: 90 MCQs

Total for Day 1: 180 MCQs.

Similarly, Day 2 would follow the same structure, distributing the remaining MCQs and CDM cases between the two sessions.

Changes Coming January 2027

Transition to a One-Day Exam

In January 2027, the COMLEX-USA Level 3 is transitioning to a one-day format that roughly spans eight hours. This shift implies that candidates will have to complete the exam in a single sitting, potentially increasing the urgency and intensity of preparation. However, the proportion of MCQs to CDM cases will remain similar, maintaining an equivalent evaluative standard:

Projected Total MCQs: Approximately 420
Projected Total CDM Cases: Approximately 26

What Remains the Same

It's crucial to note that while the exam's structure is changing, the foundational elements—the content distribution outlined in the NBOME blueprint—will remain unchanged. This consistency ensures that candidates continue to prepare using the same competency domains and clinical presentations that have long been a part of the assessment framework.

Example of Time Management in One-Day Format

Here is an example of how a single day exam may be structured in January 2027:

Session 1: 210 MCQs
Break: 30 minutes
Session 2: 210 MCQs
Break: 15 minutes
CDM Cases: 26 cases

Total Time: Approximately 8 hours including breaks. By managing time effectively during the exam, students will be able to maximize performance across all components.

Conclusion

In conclusion, understanding the structure and format of the COMLEX-USA Level 3 exam is critical for effective preparation. The transition to a one-day exam in January 2027 will require adjustment in candidate strategies, yet the familiarity of the exam's content distribution offers a stable platform to base study efforts on.

Candidates must be proactive about their time management and familiarize themselves with session formats to seamlessly navigate the challenges posed by the exam. By doing so, students will put themselves in the best possible position to achieve success.

Study Notes

The 2025-2026 exam format is two-day, four-session, with a mix of approximately 420 MCQs and 26 CDM cases.
Authorized breaks between sessions allow for rest and refocusing.
Transitioning to a one-day format in January 2027, with a similar mix of MCQs and CDM cases.
Content distribution from the NBOME blueprint remains unchanged.
Effective time management is crucial for success in both the current and new formats.
