Which ABFM Maintenance of Certification Path Fits You Best?
Two Pathways, One Standard
Since 2021, the American Board of Family Medicine (ABFM) has offered diplomates two options for maintaining certification:
- Longitudinal Assessment for Family Medicine (LA-FM) — a web-based exam taken in short segments over four years.
- The traditional one-day Family Medicine Certification Examination (FMCE) — the long-standing, in-person, high-stakes exam given at Prometric centers.
Both assess the same knowledge — the differences lie in the format, timing, flexibility, and exam-day experience.
The Traditional One-Day Exam (FMCE)
The Family Medicine Certification Examination (FMCE) remains a rigorous, single-day test of comprehensive clinical knowledge under timed conditions.
- Structure: Four timed sections of 75 multiple-choice questions (300 total)
- Time: 95 minutes per section, plus 100 minutes of pooled break time
- Delivery: In-person at Prometric test centers (U.S. and international)
- Windows: Twice yearly (April and November), with multiple testing dates in each window
- Results: Typically posted 6–8 weeks after the testing window closes
The format is identical for initial certification and for diplomates maintaining certification.
The Longitudinal Assessment for Family Medicine (LA-FM)
he Longitudinal Assessment replaces a single test day with a continuous, feedback-driven process. Diplomates answer short, case-based questions online every quarter, reinforcing clinical knowledge throughout the four-year cycle.
- Cycle length: Four years
- Questions: 25 per quarter (100 per year; 300 counted for scoring)
- Platform: Secure, web-based, open-book but timed (approximately five minutes per item)
- Flexibility: Complete questions any time within each quarterly window
- Feedback: Immediate results and explanations with references
Blueprint: The Same Foundation
Both exams follow the 2025 ABFM content blueprint:

Key Advantages of the Longitudinal Assessment
- Reduced test anxiety: Knowledge is demonstrated over time, not one day.
- Integrated learning: Each question provides feedback and citations.
- Flexibility: Quarterly pacing fits busy practice schedules.
- Adaptability: Pause and resume within the four-year cycle.
- Evidence alignment: Reinforces current guidelines through ongoing, feedback-driven learning
Early ABFM data show high completion and satisfaction rates among participants, with most diplomates meeting the passing standard well before the end of the four-year cycle.
Advantages of the Traditional One-Day Exam
- Familiar format: Mirrors previous board experiences.
- Single commitment: One preparation period, one test day.
- Predictable structure: Twice-yearly schedule simplifies planning.
- No ongoing quarterly requirements: Best for those who prefer one defined preparation period and a single test day.
For diplomates who perform well under exam pressure, this remains a strong option.
Participation and Performance Trends
ABFM’s 2024 Annual Report notes that over 80 % of eligible diplomates now choose LA-FM. The one-day exam remains available for those preferring it or who need to meet certification after an incomplete LA-FM cycle.
Performance and reliability data show comparable pass rates and psychometric validity between formats.

Both satisfy the same certification standard and result in the same ABFM diplomate status.
Common Misconceptions
Myth: LA-FM is easier.
Fact: Both follow the same passing score and blueprint.
Myth: LA-FM replaces CME.
Fact: It complements CME and fulfills part of the ongoing certification activity requirements.
Myth: Failing LA-FM ends certification.
Fact: You can meet the certification requirement by taking the one-day exam if you do not meet the LA-FM passing standard.
FAQs
Q1: Can I switch pathways during the cycle?
Yes. You can switch from LA-FM to the FMCE (or vice versa) at any time. Only the performance in your current pathway counts.
Q2: Is LA-FM truly open book?
Yes, but questions are timed — approximately five minutes per item — so searching for answers is limited and still requires clinical knowledge.
Q3: Does choosing LA-FM affect my credentialing or hiring?
No. Both pathways lead to the exact same ABFM certification.
Q4: Who benefits most from the one-day exam?
Physicians who prefer a single, defined preparation period; those who perform well under timed conditions; or those who need to fulfill certification quickly.
Q5: Who benefits most from LA-FM?
Physicians who prefer paced learning, dislike high-stakes test days, or want continuous reinforcement of guidelines.
Next Steps
- Review your personal learning style and schedule.
Do you prefer steady, quarterly engagement or one concentrated study period? - Look at your work-life constraints.
If quarterly deadlines are difficult, the one-day exam may be better. - Check your ABFM Physician Portfolio.
Look at your certification timeline and cycle status before choosing a pathway. - Review recent performance data.
If you’ve taken ITEs or CKSA items, see whether the LA-FM style works for you. - Consider your anxiety profile.
High-stakes test environments favor the traditional exam; continuous assessment favors LA-FM. - If uncertain, start with LA-FM.
You can always switch to the one-day exam later if needed. - Download the official ABFM LA-FM guide.
