When should you take the LSAT?

Two things decide the right date, and neither is when you feel ready. The first is when applications are due for the cycle you want. The second is whether a retake would still fit if the first score is not the one you wanted.

Work backward, and leave a retake in the plan

Start from the cycle you are applying in and count back: applications go in, so the score has to be released before that, so the test has to be sat before that, so preparation has to start before that. Doing this on paper usually reveals that the comfortable-feeling date is later than it should be.

Then add one more sitting to the plan. Not because you expect to need it — because a schedule with no room for a second attempt turns an ordinary bad day into a lost year. Planning the retake you hope not to use costs nothing; discovering there is no room for one costs a cycle.

Earlier in a rolling cycle is generally better

Many schools read applications as they arrive and admit on a rolling basis, so seats and scholarship money are more available early in a cycle than late. That argues for testing early enough that your completed application is not waiting on a score.

The counterweight is real, though, and it goes the other way: applying early with a score you could clearly have improved is usually worse than applying a little later with a better one. Early helps at the margin; the number is not a margin.

Readiness, honestly

• Your recent timed scores, not your untimed ones, are the honest signal. Untimed accuracy that has not survived a clock is not ready yet.
• Look at the trend rather than the last result. One good practice test is noise; four in a stable band is information.
• Full-lengths under real conditions are the only test of stamina, and stamina is a separate skill from accuracy.
• If your score is still climbing steadily, more time is usually worth more than the earlier date.
• If it has been flat for weeks with the same method, a later date will not fix that by itself — see the plateau guide.
