Common Questions

Questions assessing basic science concepts are covered on Step 1. However, foundational science knowledge will often be needed to answer items on Step 2 CK, even if the question is focused on diagnosis or management. You can see examples of Step 2 CK items that require foundational science knowledge here.

These examples include an explanation of why and how foundational science is needed to answer a test item that is not primarily focused on basic science. Foundational science knowledge is needed both for licensure examinations and for lifelong learning that continues beyond assessment.

Examinees who tested before the exam was updated in November 2020 saw slightly more Diagnosis items than Management items on Step 2 CK, whereas examinees who tested after the update saw equal amounts of both types of test items. The proportion of items allocated within Organ Systems did not change. More detail is available here.
