NCLEX-RN Passing Standard Explained: What “0.00 Logits” Means in Plain English

Somewhere in your NCLEX research you will hit the phrase “the passing standard is 0.00 logits” and your brain will slide right off it. It sounds like a typo. Zero of what? Zero questions right?

The number is real, it is meaningful, and it takes about five minutes to understand properly. It is also worth understanding, because it explains why the NCLEX has no percentage score and why “how many did I need to get right” has no answer.

A logit is a unit of measurement, not a score

NCSBN’s own definition: logit is short for log-odds-unit. Their words on what it measures — “these units have no inherent meaning with regard to nursing content and in fact have an arbitrary zero point, but logits are practical because the probability of a correct response can easily be computed when the candidate’s ability and the item’s difficulty are known.”

Unpack that.

A logit is a scale. Two different things get placed on it: your nursing ability and the difficulty of each test item. Same ruler, both measurements. That shared scale is the whole point, because once ability and difficulty live in the same units, you can calculate the probability that a given candidate answers a given item correctly.

An item at 0.00 logits difficulty, meeting a candidate at 0.00 logits ability, produces roughly a 50 percent chance of a correct answer. Ability above item difficulty, probability rises. Below, it falls.

This is why the CAT algorithm targets items you have about a coin-flip chance on. It is aiming items at your current position on the logit scale.

The zero point is arbitrary, and that is deliberate

NCSBN says the zero point is arbitrary. That is not a hedge — it is a genuine feature of the measurement system, and it kills a lot of misconceptions.

Zero logits does not mean zero knowledge. It does not mean 0 percent. It does not mean 50 percent correct. It is a marker placed on a continuous scale, the way sea level is a marker on a continuous vertical scale. Sea level is not “zero height in the universe.” It is an agreed reference point that makes elevations comparable.

The passing standard is the same idea. NCSBN’s Board of Directors picks a point on the ability scale and says: at or above this, you are safe to practice as an entry-level registered nurse.

For the NCLEX-RN, that point currently sits at 0.00 logits.

How long it has been there, and how long it stays

The RN passing standard has been 0.00 logits since April 2013. It has been reviewed and retained four times since, in April 2016, April 2019, April 2023, and April 2026.

The current standard runs April 1, 2026 through March 31, 2029.

Before 2013 it was lower, and it climbed steadily: −0.35 in 1998, −0.28 in 2004, −0.21 in 2007, −0.16 in 2010, then 0.00 in 2013 where it has stayed. That upward march reflects a rising bar for entry-level practice over two decades.

For comparison, the NCLEX-PN passing standard is −0.18 logits, also effective through March 31, 2029. Lower standard, different scope of practice — not a statement that PN candidates are held to a lesser version of the same job.

How the standard gets set

NCSBN’s Board reevaluates the passing standard every three years, or whenever the test plan changes. In practice those cycles line up, which is why standard reviews land alongside new test plans.

The decision is not a vote on vibes. It draws on a practice analysis — a large-scale study of what entry-level nurses actually do in their first months of licensed practice — plus survey data from nurse educators and employers, and the trend in candidate performance. If entry-level practice has gotten more complex, that argues for raising the bar. If it has held steady, the standard is retained.

In April 2026 it was retained, for the fourth consecutive cycle.

What this means for your exam

There is no raw score to chase. Your result is not a count of correct answers. Two candidates can answer wildly different numbers of items correctly and land on the same ability estimate, because the items differed in difficulty and difficulty is part of the calculation.

Hard items are worth more, automatically. Not because someone assigned point values, but because getting a high-difficulty item right moves your ability estimate further than getting an easy one right. The math handles the weighting.

“At or above” is the exact wording. On a maximum-length exam, a final ability estimate sitting precisely at the passing standard is a pass. The standard is inclusive.

The standard does not move during your exam. It is fixed for the full three-year period. Nothing you do, and nothing about the day you test, shifts the line. Only your position relative to it changes.

A useful mental picture

Think of the logit scale as a vertical measuring stick with the passing standard as a horizontal line drawn across it at zero.

You start the exam at an unknown height. Every answer nudges the estimate of where you are standing — correct answers push up, incorrect ones push down, and the size of the nudge depends on how difficult that item was.

The exam is not trying to score you. It is trying to figure out, with 95 percent certainty, whether you are standing above the line or below it. When it knows, it stops.

That is what 0.00 logits means. It is where the line is drawn.

One current-events note

The NCLEX-RN first-time pass rate for US-educated candidates fell from 91.2 percent in 2024 to 86.7 percent in 2025. That drop happened with the passing standard unchanged at 0.00 logits — it had been retained in 2023 and remained so throughout. A shift in pass rates without a shift in the standard points to changes in candidate cohorts, preparation, or exam composition, not to a moved goalpost. Anyone telling you “they raised the standard” is mistaken.
