COMLEX Blueprints for Level 1, Level 2 CE, and Level 3 – to Include in Your Study Strategy

Written By: The TrueLearn Team | Share:
| Last Modified: May 7, 2024

The journey to becoming a Doctor of Osteopathic Medicine is a long one, filled with many exams, each marking an important milestone in your education. The three most important of these come in the form of the Comprehensive Osteopathic Medical Licensing Examination (COMLEX). 

As you prepare to take each, it’s useful to know what they have in common and how they differ. 

COMLEX Blueprint Similarities

Osteopathic Emphasis

It goes without saying that the primary focus of the COMLEX exams is to ensure that DO students understand and can apply osteopathic principles and practices. This emphasis sets the COMLEX apart from other medical licensing exams. Expect questions that assess your knowledge of osteopathic manipulative treatment (OMT), osteopathic philosophy, and the holistic approach to patient care.

Two Distinct Dimensions

The questions on each of the three exams fall into two categories, or dimensions. The first dimension is Competency Domains, and the second dimension is Clinical Presentations. All three exams integrate the following elements:

  • Osteopathic philosophy of whole-person health care
  • Underlying structure-function relationships
  • Interdependence of body systems
  • Self-healing and self-regulatory mechanisms
  • Osteopathic approach to patient care including osteopathic manipulative medicine and osteopathic manipulative treatment 

What differs between the three is the minimum percentage of total content they represent.

Level 1 Subject Breakdown

This test is designed to assess an osteopathic medical student’s foundation of medical knowledge and their understanding of osteopathic principles before they transition to the clinical years of medical school. COMLEX Level 1 contains 352 multiple-choice questions. There are eight blocks with 44 questions each and three scheduled breaks.

Competency DomainsMinimum %

2: Osteopathic Patient Care and Procedural Skills6%

Level 2 Subject Breakdown

This test is designed to assess the clinical knowledge and skills of the osteopathic medical student. Like Level 1, Level 2 contains 352 multiple-choice questions. There are also eight blocks with 44 questions each and three scheduled breaks.

Level 3 Subject Breakdown

Level 3 has many differences from the previous two exams. The exam is broken down into four separate sections of 3.5 hours each, given over a two-day period. And there are two types of questions: single best answer multiple-choice questions and clinical decision-making (CDM) cases. Each CDM case typically contains 2-4 questions. The exam consists of a total of 420 multiple-choice questions (taken on day one) and 26 CDM cases (taken on day two).

Serving as the final step in the COMLEX series, Level 3 assesses the candidate’s ability to effectively deliver osteopathic medical care.
