Frequently Asked Questions
Who is eligible for the AOBOG Obstetrics & Gynecology certifying exam?
Candidates must be DOs who have graduated from, or are in their 3rd or 4th year of, an AOA-approved or ACGME-accredited Obstetrics and Gynecology residency. An unrestricted US medical license, program director attestation of clinical competence, and compliance with AOBOG application timelines are required.
How is the AOBOG OB-GYN written exam structured?
The Primary Written Exam (Component 2) is offered once per year via remote proctoring, generally every April/May. The application period opens five months prior to the exam, and applications are due ~15 days prior to the exam. The exam is multi-section, computer-based, with scoring on the AOA 200-800 scaled scale.
How is the AOBOG OB-GYN exam scored?
The AOA reports scores on a 200 to 800 scaled scale, with a scaled score of 500 representing the minimum passing standard as established by AOA Certifying Boards. Pass/fail decisions and detailed performance feedback are provided by AOBOG after each administration.
What is the AOBOG oral examination?
After passing the Primary Written Exam, candidates progress to the structured oral examination. The oral exam tests clinical reasoning, operative judgment, and complication management through case-based scenarios with multiple examiners. Specific format, dates, and fees are published on the AOBOG Important Dates page.
What topics are most heavily weighted on the AOBOG exam?
Obstetrics is the largest category (~40%), covering prenatal care, hypertensive disorders, gestational diabetes, labor and delivery, postpartum hemorrhage, and infection in pregnancy. Gynecology (~35%) covers menstrual disorders, fibroids, contraception, infections, incontinence, and menopause. Gynecologic oncology (~10%), REI (~10%), and OMM in OB-GYN (~5%) round out the blueprint.
Does the AOBOG exam test osteopathic principles?
Yes. As an AOA board, AOBOG expects candidates to integrate osteopathic principles into OB-GYN care. Items address application of OMT in pregnancy (pelvic diaphragm release, sacral counterstrain, muscle energy for back pain, lymphatic techniques), with attention to positioning (left lateral after 20 weeks) and appropriate technique selection.
How long should I study for the AOBOG written boards?
Most candidates report 400-600 hours of dedicated study over 6-12 months. Most candidates layer ACOG Practice Bulletins and Committee Opinions, SMFM guidelines, ASCCP cervical cancer screening updates, NCCN gyn oncology guidelines, and AOBOG-recommended resources. Daily question-bank drilling, structured review courses, and case-based learning are essential.
What happens if I do not pass the AOBOG written exam?
Candidates who do not pass may reapply for the next administration per AOBOG policy. Detailed performance feedback by content area helps target gaps. AOBOG publishes time-limit requirements for completing the certification process after residency; candidates should consult the current AOBOG handbook for retake policies and timing requirements.
