Free ABO Practice Test
Looking for a free ABO practice test? Start one right now: 20 NOCE-style multiple-choice questions, scored instantly, with a plain-English explanation after every answer. You get one full practice test every day on a free account — no credit card, no trial countdown.
Every question is written for the actual test you're preparing for: the National Opticianry Competency Examination (NOCE), the multiple-choice exam behind ABO basic certification. Questions are drawn from all 11 study categories and weighted to match the NOCE domain distribution, so your practice score actually tells you something.
What the Free Practice Test Includes
The free test is 20 questions pulled from all 11 study categories — from ocular anatomy and ophthalmic lenses to prism, ANSI standards, and dispensing procedures — in proportions that match the NOCE domain distribution. One full test per day, every day.
Practice mode shows an explanation after each answer, so a missed question turns into a mini review session on the spot. Scoring is instant, measured against the same 70% passing bar used across the app, and your results are saved so you can see how you're trending.
Retakes stay honest. Questions are reworded between tests, math problems use different numbers each time, and answer choices are shuffled every attempt — so tomorrow's test measures what you know, not what you remember from yesterday's answer key.
If you want more volume, paid plans add 30-, 50-, and 75-question tests, unlimited attempts, adaptive practice that weights questions toward your weakest categories, and a full exam simulation: 125 questions, a 2-hour timer, and no explanations until the end. See pricing for what each plan includes.
What's on the Real ABO Exam
The ABO basic exam is the NOCE: a computer-based test of 125 multiple-choice questions with a 2-hour time limit. Twenty-five of those questions are unscored pretest items, so 100 questions count toward your result. ABO reports a pass or fail based on a scaled score rather than a straight percentage.
Content spans six domains: ophthalmic optics; ocular anatomy, physiology, pathology, and refraction; ophthalmic products; instrumentation; dispensing procedures; and laws, regulations, and standards. Ophthalmic optics, ophthalmic products, and dispensing procedures carry the most weight — around 20% each — with anatomy and laws closer to 10% apiece.
Registration has recently run $225, and the exam is offered in quarterly windows (January–March, April–June, July–September, October–December) at Prometric test centers or through ProProctor remote testing. You must be at least 18 with a high school diploma or GED. Fees and dates change, so confirm everything on abo-ncle.org before you register.
Why Realistic Practice Matters
Rereading a study guide feels productive, but recognizing a fact on a page is not the same as recalling it cold in a test center. Answering exam-style questions forces retrieval — the skill the NOCE actually tests — and shows you precisely which categories need work instead of leaving you with a vague sense of "mostly ready."
Pacing matters too. With 125 questions in 2 hours, you have just under a minute per question, and optical math is where that time disappears. Transposition, Prentice's rule, and decentration need to be automatic by exam day — drill them in practice tests, and use the optical calculators to check your work while the formulas sink in.
When the same category keeps tripping you up, go back to the study guides for that topic, then retest. That loop — test, review, study, retest — is the whole strategy.
How the Free Tier Works
A free account includes every study guide, 10 category practice questions, and one full 20-question practice test per day. No credit card required, and the free plan doesn't expire. That's enough to study seriously: take the daily test, review what you missed, read up, and come back tomorrow.

Frequently asked questions
Is this ABO practice test actually free?
Yes. A free ABO Test Prep account includes one full 20-question practice test per day, all study guides, and 10 category practice questions, with no credit card required. Paid plans add longer tests, unlimited attempts, a timed 100-question exam simulation, and adaptive practice that targets your weakest areas.
How many questions are on the ABO exam, and how long is it?
The ABO basic exam (NOCE) has 125 multiple-choice questions with a 2-hour time limit. Twenty-five of the questions are unscored pretest items, so 100 questions count toward your score. Exam details can change, so check the current exam handbook at abo-ncle.org.
What score do you need to pass the ABO exam?
Passing the NOCE requires a scaled score of 70 — which is not the same as answering 70% of questions correctly, because raw scores are converted to a standardized scale. ABO Test Prep practice tests use 70% as the passing bar so you have a concrete target while you study.
How much does the ABO exam cost?
Recent NOCE registration windows have priced the exam at $225, with a combined basic-plus-practical option at $250. Certification is valid for three years, and renewing basic ABO certification requires continuing education credits plus a $125 renewal fee. Confirm current fees on abo-ncle.org before registering.
Are these the actual questions from the ABO exam?
No. Real NOCE questions are secure and never published. These are original practice questions written to cover the same six NOCE content domains — ophthalmic optics, ocular anatomy and refraction, ophthalmic products, instrumentation, dispensing procedures, and laws and standards — in the same multiple-choice format, so the practice transfers to exam day.
