Healthcare practices change over time and we have to make sure NHA certification exams accurately test the most current and relevant tasks in each profession we serve. So, every few years NHA consults with a lot of healthcare experts, and conducts nationwide job analysis research to update or create a new test plan for a given exam.
Depending on the profession (medical assistant, phlebotomy, etc.), a test plan could change a little or a lot. Some professions are evolving rapidly and others are changing, but not as fast. That can make it hard to know at-a-glance the difference between a new and a previous test plan. That’s where the exam crosswalk comes in.
