There’s a common complaint among high school students across the country, and it has nothing to do with curfews or allowances: Internet filters are preventing them from doing online research at school. School districts must block obscene or harmful images to qualify for federally-subsidized internet access under the Children’s Internet Protection Act, passed by Congress nearly 25 years ago. But the records, from 16 districts across 11 states, show they go much further. Some of the censorship inhibits students’ ability to do basic research on sites like Wikipedia and Quora.
