The curriculum at WesternU/COMP allows our students to perform well on the national board exams. Typically, the class averages on these exams place our students at or well above the national average on the COMLEX national licensing exams, both on the exam average as well as on the first-time taker pass rate.

Examine the Curriculum

Emphasizing academic excellence, compassion, and comprehensive patient care, the four-year Doctor of Osteopathic Medicine (DO) curriculum is divided into three phases into which key osteopathic principles and techniques are interwoven. Throughout COMP's curriculum, you will learn the problem-solving skills that will enable you to effectively care for the whole patient using state-of-the-art diagnostic and treatment modalities.

  • Pre-Clerkship: The first portion of this phase (Semester 1) of the curriculum lays the basic science foundation, and teaches the key osteopathic principles that you will need to commence to the clerkship phase of the curriculum. The later part of this phase (Semesters 2 - 4) incorporates basic and clinical sciences into the in-depth study of ten human organ systems. This approach emphasizes the relevance of basic science to clinical practice. Osteopathic Principles and Manipulative Medicine (OMM) continue as the foundation of this study.
  • Clerkship Phase: During this phase (Semesters 5-8), you will complete 20 rotations comprised of the major medical disciplines and electives which provide you with the opportunity to further develop your medical knowledge and clinical skills.

For example, Courtney Martin, DO 2011, started her own research project for Parental Attitudes towards the HPV vaccinations. Learn about research at WesternU.

Early Clinical Experience
During the pre-clerkship phase, you will receive early clinical exposure through courses including Osteopathic Principles and Practices, Essentials of Clinical Medicine, Physician and Society, and Service Learning. Our students also refine their clinical skills by working with standardized patients in our Clinical Skills Lab and through participation in WesternU's service-oriented clubs and organizations. By the end of your second year, you will be well prepared to commence your third and fourth year rotations.

Learn Alongside Students in the Other Health Professions
WesternU's interprofessional curriculum provides a forum for you to collaborate and learn from students in eight other health-care programs. This curriculum provides an opportunity for early networking with other health professionals and ultimately prepares you to better serve patients through interprofessional collaboration and referrals.

Academic Support
Dedicated clinical and basic science faculty, with many years of teaching experience, are committed to working closely with you to help you succeed in our rigorous academic program. Each student has a faculty advisor who serves as a mentor throughout a student's academic career by providing advice, referral, letters of recommendation, and other support as needed.Photo of Seth Criner and quote
Additionally, you can draw on the expertise of the Learning Enhancement & Academic Development Office (LEAD). LEAD staff arrange for individual and group peer-tutoring sessions, one-on-one stress relief sessions, and workshops on topics such as time management, test-taking skills, and learning styles.

Support for COMLEX and USMLE board exam preparation is also provided though both the College faculty and the LEAD office.


Facilities and Technology
The preclinical classrooms support your learning using state-of-the-art technology including Ethernet ports at every seat, a built-in multi-media podium, and four large projection screens used to display PowerPoints, outlines, videos, and photos related to lectures.

Classrooms are also equipped with the Apreso system that digitally records lectures for online access and review as needed. The system allows students to review select portions of a lecture or even the entire lecture as needed.

As a WesternU osteopathic medical student, you will learn in a variety of settings including the classroom, anatomy lab, OMM lab, clinical skills lab, clinics, medical offices, and hospitals.

You will also make use of the Harriet K. and Philip Pumerantz Library, a four-story 34,000-square-foot building renovated in 2001. The library features hard-wire and wireless capabilities for laptop use in any room; group study rooms and numerous study carrels; and two computer labs. The library's collection is extensive with over 27,000 volumes and journal subscriptions to over 500 print journals and access to more than 9,000 electronic journals. Electronic databases are available both on-campus and off-campus through the Library's e-resources page.
