The CNSC® exam tests the knowledge that is required for the delivery of safe and effective nutrition support as defined by the evidenced-based, interprofessional practice audit. Some individuals may find the test to be "basic" while others may view the test as "advanced".
In order to have a legally and practically defensible exam, it must represent clinical practice. Practice drives certification; certification does not drive practice. The NBNSC uses the practice audit to validate the content of the exam. This is considered the highest level of supporting evidence. From there, the test items are developed with the assistance of a psychometrician.
