Before you begin your Kaplan program, you must establish a “baseline composite score” in 1 of 2 ways: By providing an official score issued by the test administrator for the same test you’re prepping for, or If you have never taken the test before, by taking a proctored Kaplan diagnostic. For certain programs, we allow you to take a Kaplan diagnostic online, under self-proctored conditions. Then, when determining if you did or didn’t score higher on your official test, Kaplan compares your baseline composite score with your overall official score on test day.
