Some of my work experiences came from working with my CNA license, so I can share my personal experience with you. I'm not sure if you're asking about pay rate or pay raise, but the pay rate depends on several things like the work setting/employer and your qualification and experience. It also depends on which city you live in, so if you're thinking of applying to a certain company, for example, Glassdoor is one place you can look up this information to a certain extent. Then of course, you could call or email the recruiter or the HR department of the company although there usually seems to be the perception that this might give the company a negative impression. If you're asking about pay raise, hospitals tend to give you either a set % or amount every year you stay with them. I hope this helps.
