Need help with going about getting tested for the first time!

My partner has told me that he has to get tested for chlamidia. He didn't know this until after we had sex. I've never had to get tested and I have no idea where to go and what to do and if I do go, if my parents will see because of the antibiotics for our insurance. It also doesn't help that I go to a Christian college and even getting caught having sex, you could be removed from the school. I just need help.
