Community Service Hours for High School?

How many community service hours do you need to get into high school? Do you need community service hours or is it just for college? If you do need them for high school does it differ from area? And to get these hours put into use, you have to fill out a community service form, right? Can you make the community service forms, or do the organizations usually have them? And who do you submit the community service forms to? I know this question seems stupid but I’m only in 8th grade. Thanks.
