Your LSAT score starts as a simple count of right answers. LSAT score conversion changes that count into the scaled score schools see.

The steps are easy once you break them down.

This process happens the same way for every test taker. It removes guesswork and keeps results fair across different exam dates.

Knowing how LSAT score conversion works can help you read your results better. It also helps you set clear goals while you study.

The scale stays steady, even when test forms change. Once you see how it works, your score report feels a lot clearer.

Understanding the LSAT Score

An LSAT score works differently than a simple percentage grade. The test first produces a raw score based on correct answers across the scored sections.

That total is then converted to a scaled score between 120 and 180. Law schools use this scaled score as one of the core requirements for LSAT admissions review.

A percentile rank adds context by showing how a score compares with recent test takers. A high percentile does not mean a high percentage of correct answers.

Raw scores, scaled scores, and percentiles each show a different part of your performance. Knowing these terms makes the conversion chart easier to read.

How to Convert a Practice-Test Score?

Converting a practice-test result correctly depends on the source of the test and the format it follows. Official PrepTests usually include an answer key and a specific conversion table, while third-party tests may provide only an estimate.

Follow these steps to avoid using the wrong scale.

Step 1: Identify the Exact PrepTest

Before calculating a score, confirm the complete PrepTest number and its format. Current official tests use three-digit numbers beginning with 101, while older versions may include the discontinued Analytical Reasoning section.

The official LSAT practice-test page can help verify the structure.

Record the number, confirm that the sections match the current LSAT, and avoid combining material from unrelated tests because an outdated conversion chart may produce a misleading result.

Step 2: Count Only Scored Questions

Calculate the raw score using only the two scored Logical Reasoning sections and the scored Reading Comprehension section. Do not include the fourth multiple-choice section because it is unscored.

Review the test information carefully before adding correct answers, since the experimental section may appear in different positions.

When the unscored section cannot be identified confidently, label the manually calculated result as an estimate rather than treating it as a verified practice-test score.

Step 3: Find the Test-Specific Conversion Chart

Locate the conversion table provided with the exact PrepTest rather than relying on a general online chart. Each official scale reflects that test’s scored-question total and difficulty adjustment.

Information about official preparation materials is available through LSAC’s test-preparation resources.

Third-party calculators can support rough planning, but they may produce slightly different results. Use the official table first and never assume that one conversion scale applies equally to every PrepTest.

Step 4: Match the Raw Score to the Scaled Score

After calculating the raw total, find that number in the PrepTest’s conversion table and read the corresponding scaled score between 120 and 180.

Check the row and result carefully before saving the score. Because conversion scales vary slightly between tests, the same number of correct answers may not always produce the same scaled result.

The chart attached to the completed PrepTest should therefore take priority over estimates from general score converters or unofficial online tables.

Step 5: Record Both Scores

Save the raw score and scaled score together after every full-length practice test. Include the PrepTest number, completion date, section-level accuracy, timing difficulties, and any testing conditions that may have influenced performance.

Tracking both scores makes it easier to compare accuracy across different conversion scales and identify meaningful progress.

Consistent records also prevent one unusually strong or weak result from shaping the study plan more heavily than the broader pattern across several recent practice tests.

LSAT Score Conversion Chart

LSAT score conversion starts with your raw score, the number of questions you answer correctly. Here is how that raw score converts to a scaled score and percentile:

Approximate raw score

Approximate scaled score

Approximate percentile

75–78

180

99.9th

70–71

175

98.9th

66–67

170

95.1st

58–60

165

86.5th

50–52

160

72.9th

46–48

155

55.9th

41–43

150

38.1st

35–37

145

22.5th

29–31

140

11.5th

18–20

130

2.3rd

0–14

120

Below 1st

Note: These figures are planning estimates. Official raw-to-scaled scales vary by PrepTest. Percentiles use LSAC’s published 2022–2025 testing-year data.

Why LSAT Score Conversion Changes From One Exam to Another?

LSAT forms are not identical, so small differences in question totals and difficulty require adjustments to keep scaled scores comparable.

  • Question Totals May Differ: Individual PrepTests can contain slightly different numbers of scored questions, which changes the available raw-score range.
  • Difficulty Varies Between Exams: A harder or easier test form may require a slightly different raw-to-scaled conversion.
  • LSAC Uses Equating: This statistical process adjusts for difficulty differences and supports consistent 120–180 scores across test dates.
  • Missed-Question Allowances Change: The same number of incorrect answers may produce different scaled scores on two PrepTests.
  • Test-Specific Charts Are More Accurate: Use the official conversion table attached to the completed PrepTest instead of relying on a universal chart.

These differences help preserve fairness across LSAT forms. The exact PrepTest conversion chart remains the most reliable scoring source.

What’s a Good LSAT Score?

There is no universal answer to what a good LSAT score is because its value depends on target schools and the applicant’s admission or scholarship goals. A 160 may be competitive at one school but below the median at another.

Scoring below the 25th percentile does not rule out admission, although other application elements may need to carry more weight.

A score near the median generally matches recent entering classes, while one above the 75th percentile can strengthen admission prospects and scholarship leverage.

These ranges are benchmarks, not guaranteed cutoffs. Applicants should compare their results with each school’s 25th, 50th, and 75th percentile LSAT scores using current ABA law school statistics.

Law schools also review undergraduate grades, course difficulty, personal statements, recommendations, and experience, as explained in the LSAC Official Guide.

How Many Questions Can You Miss?

There is no permanent answer to searches such as “10 wrong on LSAT score” or “12 wrong on LSAT score.”

Missed-question targets work best as planning guides for accuracy and pacing, not as fixed promises about the final score:

Target Score

Estimated Questions Missed

Practical Interpretation

175

5–6 wrong

Near-perfect consistency

170

9–10 wrong

Highly competitive result

165

16–18 wrong

Strong at many schools

160

24–26 wrong

Competitive range varies

150

33–35 wrong

School selection becomes important

Missed-question ranges can help set practical accuracy goals during preparation. However, they should remain flexible because each PrepTest may convert raw scores differently. Use the official test-specific scale to confirm the final result.

Note: These missed-question figures are estimates only. Actual scoring scales shift slightly between PrepTests, so treat these numbers as flexible planning guides, not fixed targets.

How to Estimate Your LSAT Score From Practice Tests?

A practice-test score becomes more useful when the correct test format, scored sections, and conversion chart are used consistently. The following process provides a practical estimate while reducing common scoring errors.

  • Identify the Exact PrepTest: Record the full test number and confirm that it follows the current LSAT format before calculating the score.
  • Count Only Scored Questions: Add correct answers from the two scored Logical Reasoning sections and the scored Reading Comprehension section.
  • Exclude the Unscored Section: Do not include the experimental or variable section when determining the raw-score total.
  • Use the Test-Specific Conversion Chart: Match the raw total with the corresponding 120–180 scaled score provided for that exact PrepTest.
  • Track Several Recent Results: Record the raw score, scaled score, section accuracy, and timing issues to identify a dependable performance range.

General online calculators may provide quick estimates, but the official chart attached to the specific PrepTest is more reliable. Comparing several recent tests gives a clearer image than relying on one unusually strong or weak result.

How Law Schools Use Your LSAT Score?

Law schools consider the LSAT alongside academic records, written materials, recommendations, and experience.

The score helps admissions committees compare applicants and assess how each result fits the school’s recent entering-class profile.

LSAT Consideration

How Schools Use It

What It Means

Overall review

Considered with the full application, not as a fixed cutoff

Strong GPA, essays, recommendations, and experience may offset a lower score

Credential Assembly Service

Scores are reviewed with transcripts and other materials

The LSAT is assessed within the applicant’s broader record

25th percentile

Marks the lower end of the recent entering-class range

Scores below it may need stronger supporting factors

50th percentile

Represents the school’s recent median score

A similar score usually falls within the typical range

75th percentile

Indicates a result above most admitted students

It may improve admission and scholarship positioning

Multiple attempts

Schools receive all reportable scores and apply their own policies

Review each school’s approach before retaking the LSAT

LSAT ranges are useful reference points, not guaranteed admission thresholds.

Applicants should compare their scores with current school data while also evaluating GPA, application quality, scholarship goals, testing history, and the overall strength of their candidacy.

Common LSAT Score Conversion Mistakes

Small scoring errors can create misleading practice results and unrealistic application targets. Avoid these seven common mistakes:

  • Using an Old-Format Chart: Logic Games ended after June 2024, so older question totals may not match the current LSAT.
  • Counting the Unscored Section: Only the three scored multiple-choice sections contribute to the raw score.
  • Treating a General Chart as Exact: The official conversion table for the specific PrepTest should take priority.
  • Confusing Accuracy with Percentile: Answering 70% correctly does not automatically mean you the at the 70th percentile.
  • Calling One Score Universally Good: Competitiveness changes by school, GPA, application cycle, and scholarship goals.
  • Using an Outdated Percentile Chart: LSAC updates percentile rankings annually, so older figures may be inaccurate.
  • Relying on a Single Calculator: Different tools may assume different question counts or average different official scales.

Checking the test format, scored sections, official conversion chart, and current percentile data helps keep practice results accurate and application targets realistic.

Frequently Asked Questions (FAQs)

Does LSAC Round Raw Scores?

No. Raw scores are already whole numbers because they simply count correct answers across the scored sections. The score is not created by rounding a percentage.

Can Two Raw LSAT Scores Convert Differently?

Yes. The same number of correct answers can yield slightly different scaled scores across two test forms. Each official PrepTest may use a different conversion scale to account for variations in difficulty and in scored question totals.

Is the Experimental LSAT Section Identifiable?

Candidates should not assume they can reliably identify the experimental section while testing. The unscored section may be Logical Reasoning or Reading Comprehension and can appear at different points.

Do Law Schools See the Raw LSAT Score?

Law schools primarily receive the official scaled score and related score report information. They do not use the applicant’s number of correct answers as the primary admissions measure.

Can a Lower Percentile Still Be a Good Result?

Yes. A lower percentile may still support admission at schools whose recent entering-class scores align with that result. Its value also depends on GPA, written materials, experience, and scholarship goals.

Scoring It Up

LSAT score conversion follows a clear process from start to finish. Your raw score always turns into a scaled score through a steady process.

That process helps keep results fair across different test versions. Once you understand LSAT score conversion, your practice scores start to make sense.

You can track your progress with more clarity and less guesswork. Use this knowledge to guide your study plan going forward. Check your practice scores against the official chart when you can.
