General schools, especially those with junior college or above, do not encourage students to get tattoos. If students get tattoos at school, they will get zero points. If they have tattoos, they will be secretly carried out by individuals, which will arouse people's discussion. Some schools clearly stipulate that students are not allowed to have these behaviors during their studies. But now, as a relatively open society, as long as it does not affect others and has no negative impact on the school, the school will not take care of it. As for whether they can enter the school, I don't think the general school will stop them, but you should not be too ostentatious.
