How Good is a 143 on the LSAT?

Most people looking at a 143 are looking at a diagnostic. That number says far less about your ceiling than it feels like it does.

Do not build a school list yet. A 143 is far enough below the range where medians start that the useful conversation is about the next few months, not the next application cycle.

The short answer

Too early to say. A 143 almost always means a diagnostic, and a diagnostic measures unfamiliarity rather than ability.

What each point is worth from 143

+1 → 1442.9+2 → 1456.1+3 → 14610.2+5 → 14817+10 → 15335.6percentile points gained
Percentile points gained by moving up from a 143. Because the curve flattens as it climbs, the same number of scaled points is worth steadily less the higher you start.

The 20th percentile reads worse than it plays. The bottom half of the LSAT scale is dense, which is why the numbers look harsh and also why they improve so quickly once you start moving.

The shape of the curve matters more than the point on it. From a 143, one more scaled point moves you 2.9 percentile points, and five moves you 17. Those two figures are what any retake decision actually rests on.

How to move up from 143

A 143 usually is not a knowledge problem. It is a recognition problem — patterns you have not yet learned to spot with a clock running, which is a far more fixable thing than it feels like.

Order matters more than volume here. Accuracy first with the clock off, then section timing, then full tests. Almost everyone does it backwards, starts with timed full tests, and spends months confirming they are inconsistent without ever finding out why.

Before any of that, sit one properly timed test under real conditions — our guide on reading a diagnostic covers what to look for — and if law school is a serious plan, build out from a six-month schedule.

143 to 148: what it costs

Logical Reasoningabout half the scored questions+6Reading Comprehensionfour passages, 26-27 questions+3Anywhere (pacing)questions lost to the clock, not to difficulty+2
A five-point move at this level is worth about 11 more correct answers on a typical form. Raw-to-scaled conversion varies by test, so treat this as the shape of the job rather than an exact quota — the conversion chart has per-form detail.

The useful map here is tiers, not percentiles. From a 143 the next tier that changes your options is Sub-T100 / regional, and it starts around 150.

Closing a gap that size takes a real timeline. Worth doing — but worth checking first that the schools up there are the ones you want.

What a higher score would actually open up

Before deciding how hard to push, go and see what the push buys. Enter a 143 and your GPA into the law school admissions calculator, then change the score to 148 and compare the two school lists side by side.

The LSAT percentile curve is steepest through the 140s and 150s and almost flat above 172. A 143 sits at the 20th percentile.

What a 143 means as a range

A 143 is really the range 140–146
14314013th14630th120140160180
LSAC reports a standard error of measurement near 2.6 points. The shaded window is the range a 143 actually represents — the 13th to the 30th percentile, a spread of 17.6 percentile points.

Sit the same test twice with the same ability and you will not get the same score. The measurement error runs to roughly 2.6 points, so a 143 is shorthand for the range 140 to 146.

Down here that window is expensive. Its ends are 17.6 percentile points apart, so two sittings that felt identical can leave you looking like meaningfully different applicants. Since schools keep only your best score, that is an argument for sitting again.

Should you retake?

If a 143 came from a diagnostic or a sitting you did not really prepare for, it is not a ceiling and you should not treat it as one. The 17 percentile points between here and a 148 are the most recoverable on the test.

Start with untimed accuracy on logical reasoning, since it is the largest share of the test, and only add the clock once accuracy holds. Prep hours against score increase sets realistic expectations for how long that takes.

A 143 against every tier

Tier figures come from our law school tier page, which aggregates ABA 509 medians by ranking band. Individual schools vary, so treat the tier as a starting point.

What to do next

Give it a real preparation cycle first. Scores in this range routinely move ten points or more once the format stops being unfamiliar, and no decision made now survives that.

Frequently asked questions

Which schools report a median around 143?

There is no tier or school in our tables where a 143 is the typical admitted score.

Is a 143 a high LSAT percentile?

Roughly 80% of test takers reach 143 or higher, which places the score at about the 20th percentile.

Does a 143 make law school realistic?

A 143 is below every median on our table. Accredited schools do admit in this range, but the leverage right now is in the 17 percentile points between 143 and 148.

Does a retake make sense at 143?

A band of 140-146 is worth 17.6 percentile points of variance. With schools keeping the higher score, that asymmetry argues for a retake.
