Over 4.5 million web pages are contained in the block-site categories. All sites that are blocked are reviewed by N2H2 staff before being added to the block lists. Updates to the block lists occur daily, automatically. Technical support and system monitoring is available 24 hours a day. Adults can override the filters using passwords.

Adults who want to access filtered sites need to do so off of the school s network.
