text: Many students have other extra curricular activities, and jobs in or out of the house they must participate in. Therefore, I'm sure these students don't have the time after school to do community service. If those kids had to do community service, it would most likely add stress to their lives and give them less time to do homework, so their grades could begin to slip. On the weekends is when kids relax and have fun with their friends and family, so it wouldn't be a good idea to make community service time on the weekend.
