After earning your optometry license, you may wonder whether pursuing American Board of Optometry (ABO) certification is worth the additional time and effort.

While ABO certification is not required for licensure, many optometrists choose to become board certified as a way to demonstrate their commitment to lifelong learning, clinical excellence, and evidence-based patient care.

If you're considering taking the ABO examination, this guide explains the benefits of certification and offers practical study strategies to help you prepare.

What Is the American Board of Optometry (ABO)?

The American Board of Optometry is an independent organization that offers voluntary board certification for licensed optometrists who meet eligibility requirements and successfully complete the certification process.

Unlike the NBEO examinations, which are required for initial licensure, the ABO examination is designed for practicing optometrists seeking to demonstrate continued clinical competency.

Why Should You Become ABO Certified?

Every optometrist's career is different, but many choose board certification for several reasons.

1. Demonstrate Your Commitment to Clinical Excellence

Board certification signals that you have met additional professional standards beyond initial licensure and are committed to maintaining current clinical knowledge.

2. Stay Current with Evidence-Based Care

Eye care continues to evolve with:

  • New pharmaceuticals

  • Updated clinical guidelines

  • Advances in diagnostic technology

  • Emerging treatment options

  • New research findings

Preparing for the ABO examination encourages a structured review of current clinical standards.

3. Professional Development

Many optometrists appreciate the opportunity to formally review clinical knowledge that may not be encountered every day in practice.

Preparing for the examination can strengthen confidence in diagnosing and managing a broad range of ocular conditions.

4. Career Advancement

Depending on your practice setting, board certification may support professional development and demonstrate a commitment to continuing education.

While requirements vary among employers and organizations, some practices value or encourage board certification as part of ongoing professional growth.

What Topics Are Covered on the ABO Exam?

The examination focuses on the knowledge and clinical decision-making expected of a practicing optometrist.

Common content areas include:

  • Comprehensive eye examinations

  • Ocular disease

  • Glaucoma

  • Cornea and external disease

  • Retina

  • Neuro-ophthalmic disease

  • Pediatric eye care

  • Contact lenses

  • Low vision

  • Systemic disease and ocular manifestations

  • Pharmacology

  • Evidence-based management

  • Clinical guidelines

  • Patient safety

Rather than emphasizing basic science, the examination focuses primarily on clinical application.

How Long Should You Study?

Most practicing optometrists benefit from 6 to 12 weeks of consistent preparation, depending on:

  • Years since graduation

  • Clinical experience

  • Time available each week

  • Familiarity with current clinical guidelines

Even studying 30–60 minutes most days can be effective when done consistently.

How to Study for the ABO Examination

1. Create a Study Schedule

Break the material into weekly topics instead of trying to review everything at once.

Example:

Week 1

  • Cornea

  • External disease

Week 2

  • Glaucoma

Week 3

  • Retina

Continue working through each major content area while scheduling regular review sessions.

2. Focus on Clinical Decision-Making

The examination is designed to assess how you manage patients.

Ask yourself:

  • What is the diagnosis?

  • What additional testing is indicated?

  • What is the appropriate treatment?

  • When should the patient return?

  • When is referral appropriate?

Learning to think through complete patient management is often more valuable than memorizing isolated facts.

3. Review Current Clinical Guidelines

Practice patterns change over time.

Spend time reviewing:

  • Preferred treatment recommendations

  • Updated medication options

  • Current glaucoma management

  • Dry eye treatment strategies

  • Retinal disease management

  • Systemic disease recommendations

Staying current is one of the primary goals of board certification.

4. Complete Practice Questions

Practice questions help you:

  • Identify weak areas

  • Improve clinical reasoning

  • Become familiar with examination style

  • Build confidence

After each practice session, review why every answer is correct or incorrect—not just whether you chose the right option.

5. Review High-Yield Pharmacology

Be comfortable with:

  • Drug mechanisms

  • Indications

  • Contraindications

  • Adverse effects

  • Drug interactions

  • Ocular toxicities of systemic medications

Medication knowledge is an important component of clinical practice.

6. Review Clinical Images

Spend time identifying:

  • Fundus photographs

  • OCT scans

  • Visual fields

  • Corneal pathology

  • Optic nerve abnormalities

  • External disease

  • Retinal disorders

Image recognition is an essential clinical skill.

7. Don't Forget Systemic Disease

Many ocular conditions are associated with systemic disease.

Review common associations involving:

  • Diabetes

  • Hypertension

  • Autoimmune disease

  • Neurologic disorders

  • Infectious disease

  • Medication toxicity

Understanding these relationships strengthens both examination performance and patient care.

Common Mistakes to Avoid

Many candidates:

  • Wait until the last minute to study.

  • Focus only on memorization.

  • Ignore practice questions.

  • Skip reviewing current treatment guidelines.

  • Avoid weaker subject areas.

Instead, aim for steady, consistent preparation over several weeks.

Final Study Tips

Before exam day:

  • Develop a realistic study schedule.

  • Review a little each day.

  • Practice applying knowledge to patient cases.

  • Stay current with evidence-based management.

  • Get adequate sleep during the week before the examination.

Consistent preparation is far more effective than trying to cram large amounts of information in the final days.

Final Thoughts

The American Board of Optometry certification examination offers licensed optometrists an opportunity to demonstrate continued professional development and a commitment to lifelong learning.

Whether you've been in practice for two years or twenty, preparing for the examination is an excellent way to refresh your clinical knowledge, review current standards of care, and strengthen your confidence in managing patients.

At OD on the GO, we believe learning doesn't stop after licensure. Our goal is to provide practical, evidence-based educational resources that help optometrists continue growing throughout their careers—whether you're preparing for the ABO examination, expanding your clinical knowledge, or simply striving to provide the best possible care for your patients.
