I'm doing a paper for my business admin class. I'm trying to compare daycares around my town. Specifically the hiring process. I worked at a daycare a long time ago but apparently the laws in my state have changed and now you need whats called a CDA or certain classes to be a teacher.

My question is:
How do these centers know if you actually have your CDA or classes. I assume you bring in something showing that you do or do they/can they look it up threw the state. Do they have to look it up threw the state? I've gotten mixed answers.
