The mean reliability coefficients for the eight LSAT administrations in the 2021-2022 testing year were all above 0.90. LSAT test forms typically have reliability coefficients over 0.9. Reliability coefficients for LSAT test forms are published in LSAC’s annual Interpretive Guide for LSAT Score Users. Values of 0.9 or higher indicate a very reliable test form. The larger the value of the reliability coefficient, the more reproducible a test taker’s performance should be. Reliability coefficients are measured on a scale from 0 to 1. Reliability coefficients indicate how reproducible a test taker’s performance would be over repeated administrations of that test.

To assess the reliability or consistency of LSAT scores, a reliability coefficient is computed for each LSAT test form.

The reliability of a test is a measure of the precision of the scores reported on that test.
