Schools should filter internet access to prevent students from viewing inappropriate content. Filters block adult entertainment and content minors are legally prohibited from viewing. While filters may overblock some educational sites, they are necessary to focus students on learning and avoid distractions from games and social media. Filters also protect students' privacy and safety by restricting personal information and contact from predators. However, filters are not perfect and sometimes block valid content, so teachers should help students access appropriate sites for assignments.
