Test Day

In-person Testing

You should arrive at the testing center 15-30 minutes early. Upon entering the testing center, you must provide 2 forms of identification, which include a photograph and your name and signature.

Electronic devices, notes, reference materials, and other items are not allowed in the test room, so you will be asked to leave those items in a secure locker until the exam is over.

Before the exam begins, you will be given the opportunity to take a practice test to become familiar with the test design and computer. Once the practice test is complete, you will begin the real exam.

Live Remote Proctoring

You should sign in to the testing portal at least 15 minutes early. During the check-in period, your identification will be checked, and you will be asked to scan your testing area using your webcam. The remote proctor will then go over the testing rules and expectations to ensure you are prepared.

Once the proctor has determined you are ready, the exam will begin.

How the Inpatient Obstetric Nursing Exam is Scored

This exam is scored using a criterion-reference method, meaning that the passing score is based on a criterion predetermined by a set of subject-matter experts.

When you receive your official score report from the NCC, it will reveal your pass/fail status, but it will not tell you what your final score is. Instead, it will provide you with feedback on each section of the exam in the form of single- or two-word descriptors: Very Weak, Weak, Average, Strong, and Very Strong.
