Is this for certification in OHN or a degree in OHN?
If it is for certification, here is what I did.
1. Work onsite as an OHN. Get all the hands on you can. There is a great learning curve when you actually do it!
2. Get AAOHN's "Core Curriculum for Occupational and Environmental Health Nursing", 3rd ed. and read it through!
3. Enroll in a good review course. I used Annette Haag, the former president of AAOHN. Her course is absolutely tops and her resources are priceless for your practice (CDs, manuals, and articles) www.dvdandhaag.com
She has courses from the West Coast to the East.
4. Test your knowledge. Keep answering questions to focus on your strengths and weaknesses. DataChem Certistep offers individual and corporate licenses for certification prep questions. www.certistep.com
5. Find mentoring relationships with other sister/brother OHN's or other Occ Health Professionals. Join AAOHN and your local/district chapters and network, network, network! www.aaohn.org
Occupational Health Nursing is an excellent specialty of nursing. It transcends the conventional hospital setting and takes one right into the Community to be a voice of change and influence! Hope this is helpful.
