what classes do I need to take to become a social worker?

Im doing an assignment for carreres (for school) , and I have to get my resources from websites and anything that is actually educational, not AI, when I search up what classes, it always come out different, can you help me out?
Also I'm researching on social work/social service workers, so if you also know if a social worker needs any additional training licensing or certification needed that will really help me out! Thank you, bye bye!
