- Part I ABS costs $1,490 for administrations from August 2026 onward, up from $1,445.
- A non-refundable $400 late registration fee applies, with no guarantee of a Pearson VUE seat.
- NBEO's own Practice Items Databank runs $199 for the first month, $149 per renewal month.
- The exam is a one-day, two-session, 370-item test - plan your prep budget around that format.
Base Exam Fee for 2026
If you're budgeting for the National Board of Examiners in Optometry's Part I Applied Basic Science exam, the number to anchor on is $1,490. That is the fee NBEO has set for Part I ABS administrations taking place from August 2026 onward. This single fee covers your seat at a Pearson VUE test center for the full one-day exam: two sessions of 185 items each, four hours per session, plus the 15-minute tutorial and nondisclosure agreement built into the first session and an optional break of up to 45 minutes between sessions.
There is no separate charge for the two sessions, the tutorial, or the break - the $1,490 is an all-in registration cost for the testing event itself. It does not include study materials, transportation, lodging if you're traveling to a test center, or any late fees you might incur if you register close to a deadline.
Fee Increase: What Changed From Prior Cycles
Candidates who registered for administrations before August 2026 paid $1,445. The $45 increase to $1,490 reflects NBEO's periodic fee adjustments and is worth noting if you're comparing older forum posts, program handouts, or advising materials that still cite the previous number. If you see $1,445 referenced anywhere, treat it as outdated for 2026 planning purposes.
This is a relatively modest year-over-year increase in dollar terms, but it still matters when you're stacking it against prep materials, travel, and the opportunity cost of study time. Because Part I ABS is a prerequisite for licensure in all 50 states, the District of Columbia, and Puerto Rico, there's no lower-cost regional alternative or waiver path - every optometry student sits for this exact fee structure.
Late Registration and Other Add-On Costs
Beyond the base fee, the cost that trips up the most candidates is the $400 late registration fee. This charge is non-refundable, and registering late does not guarantee you a seat at Pearson VUE - you could pay the extra $400 and still face limited or no availability near your target testing window. This is one of the clearest financial reasons to lock in your registration date early rather than treating deadlines loosely.
Key Takeaway
Registering late doesn't just cost an extra $400 - it also risks losing your preferred test date entirely if Pearson VUE seats fill up. Check current windows on the ABS Exam Dates 2026: Testing Windows, Deadlines & Scheduling page and register early.
Other costs that aren't part of the official fee schedule but that most candidates end up paying include:
- Travel and lodging if your assigned or chosen Pearson VUE center isn't local
- Time off from clinical rotations or coursework to prepare and test
- Any retake fees if a section or the full exam needs to be repeated
Study Materials and Prep Costs
NBEO sells an official Part I ABS Practice Items Databank through its Test Run platform. Pricing is $199 for the first month of access and $149 for each renewal month if you need more time. Many candidates purchase one initial month, work through the item bank intensively, and then decide whether a renewal month is worth it based on how close they are to their test date.
Because the exam draws from five weighted domains - Anatomy (Gross, Neuroanatomy, Histology, Developmental), Biochemistry/Physiology, Immunology/Microbiology/Pathology, Optics, and Pharmacology - most candidates supplement the official databank with additional review resources, textbooks carried over from coursework, and structured practice tests. A detailed breakdown of what each domain actually tests is covered in the ABS Exam Domains 2026: Complete Guide to All 5 Content Areas guide, which is worth reading before you decide how to split a prep budget across resources.
Optics (31-35% of the exam)
As the single largest domain at 108-122 items, Optics deserves the largest share of both study time and any paid resources you invest in - geometrical, physical, ophthalmic, and physiological optics all fall under this umbrella.
- Prioritize practice items covering ophthalmic and physiological optics, since these tend to carry heavier item counts within the domain
- Don't neglect geometrical and physical optics fundamentals just because they feel more "textbook"
Immunology / Microbiology / Pathology (22-30% of the exam)
This is the second-largest domain and overlaps heavily with the Normal Health, Disease and Trauma condition block (228 items), within which Systemic Health alone accounts for 55-75 items.
- Treat pathology review as connective tissue linking microbiology and immunology concepts to disease presentation
- Systemic Health topics deserve dedicated review time given their outsized share of the condition-block mapping
Total Realistic Budget for Part I ABS
Putting the pieces together, here's how a realistic budget breaks down for a candidate who registers on time and uses the official practice databank for two months:
| Cost Item | Amount |
|---|---|
| Base exam fee (Aug 2026+) | $1,490 |
| Practice Items Databank, first month | $199 |
| Practice Items Databank, renewal month | $149 |
| Late registration fee (if applicable) | $400 (non-refundable) |
On the low end - registering on time and using one month of the official item bank - a candidate is looking at roughly $1,689 before any travel or third-party study resources. Add a renewal month and the total climbs closer to $1,838. Missing a registration deadline adds another $400 on top of whichever scenario applies, with no guarantee that a seat will even be available.
Cost Versus the Stakes of the Exam
A $1,490 fee is easier to stomach when you understand exactly what's riding on the result. Part I ABS is the first of NBEO's three-part licensure series, and it's required for optometric licensure everywhere in the United States plus Puerto Rico - there's no path around it. Scores convert from a raw score to a scaled score between 100 and 900, with 300 as the pass-fail cutoff, and NBEO does not grade on a curve, so the fee buys you a shot at a fixed, objective bar rather than a moving target.
Score reports post approximately seven weeks after the full administration, which means the financial and scheduling impact of a retake - another $1,490 fee, another Pearson VUE booking, another multi-week wait - is significant enough that most candidates treat first-attempt preparation as the real cost-control strategy. For context on how demanding the exam actually is and how the scoring cutoff is applied section by section, see How Hard Is the ABS Exam? Complete Difficulty Guide 2026 and ABS Passing Score 2026: Exactly What You Need to Pass.
Recent first-time pass rates - 68.7% in March 2024, following 67.1% in March 2023 and 65.3% in March 2022 - show a exam that a majority of first-time takers clear, but with a meaningful share needing a retake and its associated cost. The full data trend is broken down in ABS Pass Rate 2026: What the Data Shows.
How to Avoid Paying More Than You Should
Most of the avoidable cost in Part I ABS comes from timing mistakes and disorganized prep, not from the base fee itself. A few practical ways candidates keep their total spend closer to the minimum:
- Register early and check dates against your coursework calendar. Missing a window means either the $400 late fee or waiting for the next administration cycle.
- Sequence your review around domain weight before buying extra resources. Optics (31-35%) and Immunology/Microbiology/Pathology (22-30%) together make up more than half the exam, so prep spending should follow that weighting rather than being split evenly across all five domains.
- Use the official item bank strategically. A single focused month of the $199 Practice Items Databank, timed close to your test date, often delivers more value than starting it too early and needing a $149 renewal simply because momentum was lost.
- Treat a retake as the real cost risk. A structured first-attempt study plan, such as the one outlined in the ABS Study Guide 2026: How to Pass on Your First Attempt, is cheaper in dollars and time than paying the full fee twice.
