Is the Bar Exam Curved? How Scaling Actually Works

One of the most common bar exam myths is that the exam is curved — that a fixed percentage of candidates pass regardless of how well everyone performs. This is not true. The bar exam uses scaling (equating), not curving, and the distinction matters.

Curved vs. Scaled: The Difference

Curving

A curved exam adjusts scores relative to other test-takers. If the top score is 85%, a curve might set that as 100% and adjust everyone else proportionally. On a curved exam, your score depends on how well others perform. If everyone does well, the curve compresses scores. If everyone does poorly, the curve inflates them.

The bar exam does not work this way. Your score is independent of how other candidates perform on the same administration.

Scaling (Equating)

Scaling adjusts scores to account for differences in difficulty between exam administrations. The goal is to ensure that a given scaled score represents the same level of knowledge and ability regardless of when you took the exam.

The MBE uses statistical equating: the 25 unscored pretest questions are used to calibrate the difficulty of each exam against prior administrations. If the February exam happens to be slightly harder than the July exam, the scaling adjustment accounts for that. A candidate who would have scored 140 on the July exam will also score approximately 140 on the February exam.

This means your score reflects your performance against a consistent standard, not against other candidates.

What This Means for You

Everyone who meets the standard passes

There is no cap on the number of people who can pass. If every candidate performs well enough to meet the jurisdiction's minimum score, every candidate passes. Conversely, if no one performs well enough, no one passes.

In practice, pass rates fluctuate between administrations, but this is because candidate performance varies, not because the passing standard changes (in UBE states, the minimum score is fixed).

A harder exam does not mean fewer people pass

If a particular MBE administration is more difficult, the scaling adjustment compensates. Candidates who would have scored 140 on an easier version still score approximately 140 on the harder version. The passing standard does not move.

This is why claims that "this exam was harder than last year's" are not useful information. The scaling process exists precisely to neutralize difficulty differences.

You are not competing against the person next to you

On a curved exam, every other candidate is your competitor. On a scaled exam, they are irrelevant to your score. You are competing against a fixed standard. This should be liberating: you do not need to be better than anyone else. You need to be good enough.

How Essay Scaling Works

The MEE and MPT are graded by human graders in each jurisdiction. Raw essay scores are then scaled to the MBE to create a combined UBE score.

The scaling process adjusts for differences in grading strictness between jurisdictions and between administrations. If graders in one jurisdiction tend to give lower raw scores than another, the scaling adjustment compensates so that the final combined score is comparable across jurisdictions.

This scaling means you should not compare raw essay scores across states or across administrations. A raw essay score of 4 in one jurisdiction might correspond to a different level of performance than a 4 in another jurisdiction after scaling.

The Minimum Score Is Not a Curve

Each UBE jurisdiction sets a fixed minimum passing score. This score does not change based on how candidates perform. It is a policy decision by the jurisdiction's bar examiners.

Some states have adjusted their minimums over time (usually lowering them), but these changes are deliberate policy decisions, not automatic adjustments based on pass rates.

Common Misconceptions

"They only let X% of people pass." Not true. There is no predetermined pass rate. The pass rate is an outcome, not a target.

"The exam was easier this time, so the curve will be harsher." There is no curve. Scaling accounts for difficulty so that scores are comparable across administrations.

"If I take the bar in an easier state, I will get a higher score." The UBE is the same exam in every UBE state. Your score will be the same regardless of where you sit. Only the minimum passing score varies.

"February is harder than July." The exam is equated to be equally difficult. February pass rates are lower because the candidate pool includes more repeat takers, not because the exam is harder.

The Bottom Line

The bar exam is not curved. You are measured against a fixed standard, not against other candidates. Focus on your own preparation and performance, and ignore speculation about difficulty levels, curves, and what other people scored.
