What is a non-disclosed LSAT?
When you take a typical LSAT exam, the exam provider gives you your materials afterward. You’ll get a copy of the test booklet, a writing sample, an answer sheet, and an Item Response Report. The IRR shows you how each response to each question and the correct answer differed.
If you decide to take a non-disclosed LSAT, you will receive only a copy of your writing sample and an incomplete Item Response Report. You will not get a copy of the test booklet or the answer sheet, so you will never see those questions again.
The Item Response Report will only tell you your score and percentile rank. You won’t know how many questions you got incorrect, or on which sections.
In short, the only time you should think about not taking a non-disclosed LSAT is if you want to know which questions you got incorrect.
Should I take a disclosed vs non-disclosed LSAT?
When you take a non-disclosed LSAT, you merely get your LSAT score, score band, and percentile rank.
You don’t get a copy of the questions, your answer sheet, correct answers, or a score conversion sheet. All you receive is your score and percentile.
This might seem like all you need if you score exactly what you want on that particular exam. If you don’t reach the mark you wanted, it begins to matter a lot. How will you learn from and improve on the test you just completed if you have no idea how you performed on each section or what types of questions you struggled with?
This is why, in my opinion, taking a disclosed test makes much more sense if you have the chance. You have a good opportunity to review and focus on filling the gaps in your knowledge.
