Applying for certification

The certification test is a three-hour, 165 multiple-choice item test based on the CPHON® Test Content Outline (Test Blueprint). The Test Content Outline is based on the results of a role delineation study of basic pediatric hematology oncology nursing practice conducted in 2017.

The CPHON® Test Content Outline includes five major subject areas, each with a percentage assigned to it. Many nurses who have passed the test tell us the Test Content Outline was essential in helping them know what areas to study. Remember, only generic drug names are used on ONCC tests. Once you pass the exam, your certification is valid for four years.

Note: If you’re eligible to test, you’ll receive an Authorization to Test (ATT) within 2 weeks of applying. This ATT will open an almost-immediate 90-day testing window. You must take the test within that 90-day window.

Maintaining your certification

You should be very proud to be certified! In order to keep your certification, you need to earn points for certification renewal by completing Continuing Nursing Education, Continuing Medical Education, Academic Education credits, or have work published in publications or give presentations. Follow this step-by-step guide to maintain your certification.

1. Determine where to record your points.
You'll record and submit your renewal points on LearningBuilder. You gain access to your learning plan on LearningBuilder shortly after you pass a test or take the assessment.  If you are renewing AOCN®, AOCNS® or CPON® certification, you'll be given access to LearningBuilder shortly after you renew your certification each time - you will not take an assessment.  

2. Plan your professional development.
Your assessment results or test results report will tell you the subject areas and number of professional development points – ranging from 25 to 100 – you’ll need to renew your certification. These points and the subject areas where you may earn points are reflected in LearningBuilder.

3. Select the necessary subject areas.
Use your results report or assessment results to see which subject areas you need further professional development. Then, refer back to the current Test Content Outline (Test Blueprint) to help you identify whether a program is in the subject area you need.

4. Enter your points on your learning plan in LearningBuilder.
Have your CE certificates or other documentation handy when you're ready to enter your points in LearningBuilder. It's best to enter points as you earn them to avoid a last-minute rush when it's time to renew 

5. Keep all documentation.
We strongly urge you to record your points as they are earned. Keep copies of all grade reports, copies of publications, program descriptions, educational objectives, and outlines, in case ONCC asks to review them.
